Symptoms of a Bad Thermostat In Your Vehicle

Your vehicle’s thermostat plays a major role in keeping your engine running at a regulated temperature. If the thermostat is broken, it can cause serious engine damage. In this article, we go over the primary function of the thermostat, how to diagnose a bad/faulty thermostat, and how to go about replacing your vehicle’s thermostat.

What Does a Thermostat Do?

Responsible for regulating your engine’s temperature, the thermostat is a small valve that controls coolant flow. If the engine is cold, the valve stays closed to let it warm up. However, as the engine warms up, the thermostat will slowly open, allowing coolant to flow through the radiator. This process enables the engine to remain at a safe operating temperature at all times.
​
Within your vehicle, you’ll typically find two types of thermostats: spring-loaded mechanical thermostats or electric thermostats. Regardless of the thermostat type, a failure is a major safety concern and shouldn’t be ignored. If the problem is left unchecked, your engine will overheat and potentially lead to costly repairs.

What Are The Signs of a Bad/Failing Thermostat?​

  • Overheating and Overcooling
  • Coolant Leaking
  • Strange noises coming from the radiator
  • Temperature Changes
  • Heater Problems

Overheating and Overcooling

Overheating is the most common symptom of a failing thermostat. Commonly due to corrosion or aging, your car’s thermostat can get stuck in a closed position. If this happens, the thermostat won’t allow the coolant to reach the radiator, overheating the engine and potentially causing severe damage.
​
On the other end of the spectrum is overcooling. This happens when the engine can’t reach the right temperature to properly function. In this scenario, the thermostat is stuck open and overflows the radiator with coolant, drastically reducing the engine life cycle.
​
The best way to prevent either of these scenarios is to always watch your dashboard temperature gauge.

Coolant Leaking

If you have noticed liquid dripping under your car, it is a sure sign of a coolant leak. This doesn’t mean the thermostat itself is leaking, as it contains no coolant. Instead, a gasket may be the source, preventing coolant from seeping out of the thermostat housing. Check the housing for any signs of leaks, drops, drip marks, and deposits.

Strange sounds coming from the radiator

When your thermostat is faulty/failing, it’s important to be on the lookout for strange noises coming from your radiator. You may hear rumbling, boiling, or knocking. All these signs point to an issue with your car’s cooling system.

Temperature Changes

Another symptom to look out for is an erratic, fluctuating temperature gauge. The thermostat affects the temperature of air that flows in your vehicle through the vents. If it suddenly changes from hot to cold or vice versa, this is a clear indicator of a failing thermostat.

Heater Problems

If the thermostat is stuck in an open position, no matter how high you turn up the heater, you won’t get hot air flowing through the vents. This is a clear indicator of a failing thermostat. This issue is commonly discovered during the winter season. ​

Changing/Testing Thermostat Guide

For those who want to do it themselves, you likely already know where your thermostat is located; changing it isn’t too complicated. In most cases, it’s near the top of the engine where the top radiator hose meets the engine block. When replacing the thermostat yourself, you’ll need a new thermostat, fresh coolant, a drain pan, basic hand tools, and a new gasket.
​
Step 1: Find a two-gallon container or a large bucket to catch any coolant that will spill during the process. You’ll need to reuse this fluid to refill the radiator later.
Step 2: Make sure the engine is completely cool before starting. Once cooled, locate the thermostat by following the radiator hose and remove the clamp holding it in place.
Step 3: Position a drain pan under the radiator. Drain enough coolant so that the level drops below the thermostat housing.
Step 4: Disconnect the upper radiator hose from the thermostat housing. Remove the bolts securing the housing and carefully lift it off the engine.
Step 5: Take out the old thermostat. Thoroughly clean the surfaces of both the thermostat housing and the engine block to ensure a good seal.
Step 6: Place the new thermostat into position with the spring side facing down, then secure it with the bolts.
Step 7: Put a new gasket on the cleaned mating surface, then reinstall the thermostat housing.
Step 8: Reattach the upper radiator hose and refill the radiator with the coolant you drained earlier, or use fresh coolant if needed.
Step 9: Start the engine and let it reach operating temperature. Check for any leaks around the thermostat housing and hose connections.
​
If you’re not confident or experienced working on your car’s cooling system, don’t risk it. A sloppy thermostat replacement can lead to issues with your cooling system, overheating, or leaks. ​

Signs of a Bad Power Steering Pump

Since its inclusion became standard in new vehicles, power steering has been taken for granted by most drivers. It’s easy to overlook it when working properly, but when your steering feels off, you’ll be hard-pressed to ignore the issue for long.

What Is Power Steering

Prior to the addition of power steering to most vehicles, turning the vehicle meant turning the entire weight of the vehicle. 

Traditional power steering solves this problem through the use of hydraulics, which use an incompressible fluid to amplify and transfer forces from one place to another. This allows for the movement of the steering wheel to feel light and manageable while still turning the vehicle.

How Does Hydraulic Power Steering Work?

The power steering system starts with the pump, which continuously circulates pressurized power steering fluid throughout the system. Using a component called a rotary valve, fluid is directed either back to the pump or into either side of the fluid reservoir. 

While the steering wheel is in a neutral position, all of the fluid is looped back to the pump. However, when turning, the hydraulic piston will be shifted to the side and the fluid will be directed to the opposite side’s fluid reservoir. This pressure difference will allow you to turn the vehicle with little force on the steering wheel. 

Symptoms of Bad Power Steering Pump

Whining or Groaning Sounds

One of the telltale signs of a bad power steering pump is the distinct whining noise it may make when turning the wheel. This sound is primarily caused by an effect called “cavitation”, which is when air bubbles present in the hydraulic fluid hit the impeller causing a worrisome groan. The presence of air bubbles or lack of fluid can be caused by a leak in the pump itself.

This noise doesn’t always mean your pump has an issue, as cavitation can occur from reasons such as old fluid or the introduction of air bubbles elsewhere in the system. 

“Stiff” Steering Feel

Another possible symptom of a bad power steering pump is the lack of hydraulic assistance when turning. As hydraulic fluid isn’t being pumped through the system (or at least at the same rate), your steering wheel may feel extra difficult to rotate. 

Visible Leaks

One of the most obvious signs your pump is on its way out is if it’s leaking. Of course, these fluid leaks can happen from various places throughout the steering system, but when present in the power steering pump it’s time to have yours replaced. 

A leaking pump will continually cause your vehicle to run with low fluid, which can not only damage the pump further but also the other sensitive steering components around it. 

Silver Flecks in Fluid

Although a rare problem, bits of your power steering pump can begin to dissolve into the fluid and leave noticeable flecks of metal throughout. As you might guess, there isn’t much that can be done to repair this, and the pump will likely require replacement. 

How Do I Protect My Power Steering Pump?

If you’re wondering how to avoid these issues and help your power steering pump run as long as possible, there are some simple steps you can take:

Ensure Proper Fluid Quality

The easiest step is making sure that the fluid running through your pump is in the proper condition. As fluid cavitates and fills with air bubbles it will cause rapid wear to the components within the pump. 

Keep an Eye Out For Leaks

Running the correct level of fluid is crucial to the health of your power steering pump, so any leaks in the system could cause damage to your pump if the fluid reaches a low enough level. If you notice a red fluid leaking from under your vehicle, you should have your vehicle inspected promptly by a trusted automotive professional.

Use the Proper Fluid

While all power steering fluid has the same purpose, that doesn’t mean they’re all interchangeable. Many of these fluids have different chemical makeups, which their power steering systems are designed to run and handle. However, when using the wrong fluid, it can create chemical reactions with leftover fluid and sensitive gaskets. 

Some vehicles recommend using a certain type of automatic transmission fluid in the power steering system due to their similar makeup and properties. However, you should be extra sure your vehicle is meant to run ATF rather than purpose-made power steering fluid. 

Your owner’s manual will be the most accurate place to find what kind of power steering fluid is necessary in your vehicle.

How to Add Air to Tires

Maintaining proper air pressure in your tires is vital to keeping your vehicle performing as it should, as inadequate PSI in just one tire can cause significant losses in efficiency and handling performance, increased braking distance, and increased wear that could leave you needing a replacement earlier than expected. 

If you notice an active tire pressure monitoring system (TPMS) warning on your dashboard, it likely means at least one of your tires is low on air. But that may leave you wondering, how do I actually add more air to my tires?

In this article, we’ll cover why proper tire pressure is so important and how you can add air to your vehicle’s tires when needed.

Why is Tire Pressure Important to My Vehicle?

While a slightly deflated tire may seem like something you can push down the line and continue driving on, there are a few critical reasons why this is not the best idea.

For one, deflated tires can reduce your vehicle’s MPG by a significant amount. According to the United States Department of Energy, a vehicle running 75% of the recommended tire pressure in all four tires may see efficiency drops as large as 2%-3% across all driving speeds. At 50% capacity, this effect worsens even further, with losses of up to 10% recorded at normal surface-street speeds (40 MPH). 

Beyond just efficiency, low tire pressure also affects the performance and handling of the vehicle. The low PSI allows for the tire to “flex” more than it should around corners, reducing the vehicle’s ability to stay planted during turns.

The most important reason to avoid driving on low-pressure tires is simple: safety. Low PSI causes the vehicle’s stopping distance to increase and control to decrease, potentially landing you in some dangerous circumstances. Driving on a deflated tire for an excessive amount of time can prove even worse, as the increased rate of wear could cause the tire to fail prematurely. 

How Do I Add Air to My Tires?

Now that you know the importance of keeping your tires filled up, how do you actually go about doing that? Luckily, this process is generally very simple and can be completed in a matter of minutes.

Step 1 – Find a Compressor to Use

Your first order of business is locating an air pump you can use to top off your tires. The vast majority of gas stations will have tire filling stations you can pay a few bucks to use, but at-home air compressors will also work just fine for this as well. Pull your vehicle into a spot where the hose can reach all four tires (or at least the ones you intend to fill).

Step 2 – Find Your Recommended PSI

Not all tires are created equal, and some may require a higher or lower PSI than others. The best way to find the proper pressure is to look at the sticker placed on the driver’s side door jam, which is the portion of the door that is covered when closed. Alternatively, you can likely find it by taking a look at the owner’s manual or the PSI number listed on the sidewalls of some tires. 

Step 3 – Remove the Tire Valve Caps

The valve stems, or the threaded metal stems on the wheels used to let pass through, will be covered by a valve cap which should be removed. Place the caps in your pocket or within the vehicle so you can be sure not to lose them.

Step 4 – Place Compressor Fitting Over Valve Stem

After activating the compressor and finding your optimal PSI, you’ll want to place the compressor’s fitting on the valve stem of the tire you want to fill. This will begin to fill the tire with air. 

Step 5 – Fill To Proper PSI

Now that you have air going into the tire, it’s time to fill it to the proper level. Keep an eye on the pressure gauge located on the compressor as the pressure builds, and remove the compressor’s fitting when adequate PSI has been reached. If you’ve accidentally overfilled your tire, you can press the metal pin located in the center of the valve stem to let air escape. 

Step 6 – Replace Valve Caps

Now your tire is all filled up! All you need to do now is put those valve stem caps back on. These caps are important for preventing valve stem damage from road debris and help to keep the air inside the tire.

Symptoms of a Leaking Valve Cover Gasket

 

The many gaskets we have in our cars are a small but essential piece in keeping the vehicle running safely and smoothly. There are gaskets in nearly every system within the engine, all working to keep essential fluids like oil where they should be.

Keeping oil in the engine is just as important as having oil in the first place, and that wouldn’t be possible without silicone and rubber gaskets. Metal on metal connections do not form a proper seal, and would allow oil to seep out of where it needs to be.

 

What Does the Valve Cover Gasket Do?

 

The valve cover protects some of the most vital and carefully calibrated parts of your vehicle, and keeps the high pressure oil there to lubricate it all. The valve cover gasket is exactly what it sounds like, a gasket for the valve cover. It essentially maintains the seal between the valve cover and the cylinder head, and prevents oil from escaping.

The gasket is usually made of silicone, rubber, or cork and provides a cushion for the seal. With use though, the gasket is gradually worn down by the oil and heat and can eventually no longer properly serve its purpose. 

 

What Happens When the Gasket Goes Bad?

 

As oil starts to leave the system, there are a host of issues that can come up. As your engine loses oil, the wear on internal components increases.. Low oil levels can lead to catastrophic problems for your engine, and despite a gasket replacement costing a little upfront, it’ll save massive headaches for you and your wallet down the line.

 

How Do I Know If My Valve Cover Gasket Is Bad?

 

A bad valve cover gasket has multiple different symptoms, some that are similar to other issues with your engine and some that are unique to the specific gasket. Some of the symptoms that can be signs of a bad gasket include:

 

Visible Oil Leaks 

 

When oil is able to escape, it’ll often leak onto different parts of the engine that may be visible when you pop your hood. Other times, it can drip all the way to the ground and you’ll be left with a blackish brown stain on your driveway under the engine bay. Keep an eye out for these leaks, as having an engine soaked in oil is a good indicator that something isn’t right. 

 

Low Engine Oil

 

With an oil leak comes the accompanying low oil light. If you have an oil light illuminated on your dash or suspect low oil, shut off your car and check your dipstick, as running with low oil can be harmful for your engine even in short periods of time. If you know you have low oil, top off your engine immediately and bring your car to an expert

 

Smell of Burning Oil

 

Often when oil is leaking from the valve cover, it can drip onto extremely hot parts in your engine such as the exhaust pipes or engine block. If you smell burning oil it means your engine is losing oil, and may have or will soon reach dangerously low levels. If you smell this distinct smell, make sure to take it into a service shop to locate and fix the source of the leak. 

 

Misfires

 

With a bad gasket, the oil is able to leak into the spark plug wells and eventually soak the spark plugs. This can result in your engine misfiring, which is the failure of a cylinder to ignite during the engine’s cycle. Misfires will result in reduced performance, and the spark plugs will need to be replaced. In serious cases, misfires can even lead to engine fires. It’s important to look for misfire codes on your dash, and take your car in for service as soon as you see one. In severe instances, you might see your check engine light blinking repeatedly. You should pull over immediately and have your car towed to a professional, as driving with a severe misfire can cause extremely expensive damage to your catalytic converters.

How Long Do Shocks & Struts Last?

Shocks and struts are some of those components you really only notice when they’re not doing their job properly. They keep your vehicle riding smoothly over various bumps and dips along the road, so when they’re in need of replacement, you’ll notice a decrease in ride quality.

But how long do you have until yours are in need of replacement? When should you start looking into replacing the shocks and struts on your vehicle?

Shocks vs. Struts: What Are They?

It’s common for the terms shocks and struts to be used interchangeably, and while they are both very similar in appearance, there are some major differences between these components.

Shocks

The primary purpose of shocks is to absorb the energy from dips and bumps your car’s suspension encounters. Your shocks keep your wheels in contact with the road and your vehicle under control.

Shocks dampen the effects of uneven surfaces with the use of a piston and hydraulic fluid. When going over a bump or dip in the road, the piston pushes against the hydraulic fluid, and small holes allow for fluid to slowly make its way to the other side of the piston, which creates resistance and slows down the suspension travel in both directions. 

Struts

Struts provide the same resistance to dips and bumps as well as act as a structural component of the vehicle. Struts are shocks and coil springs combined into a single component. 

Struts use the same hydraulic piston design for dampening but also make use of a strut housing and coil spring to structurally support the suspension. 

So not only do struts keep your ride comfortable, but they also provide valuable support to the spring and hold the tires in the proper position. Because of this, struts are able to take the place of upper control arms and ball joints on suspension systems that use them. 

Signs that I Need to Replace My Shocks or Struts

Suspension components fail gradually over time, which means you should keep an eye out for telltale symptoms such as:

  • Instability at highway speeds
  • Tires “bouncing” after hitting bumps
  • Leaking hydraulic fluid around shocks/struts
  • Vehicle dives forward under heavy braking
  • Vehicle sways to the side when turning
  • Squeaking or rubbing noise over bumps and dips

How Long Do Shocks & Struts Last?

The lifespan of your shocks and struts depends on a variety of factors. The make and model of the vehicle will affect it significantly, as different manufacturers use different qualities of components and suspension types. 

One of the largest of these factors is how the vehicle has been driven, as aggressive driving or harsh road conditions reduce the lifespan of suspension components. Those who often drive on uneven roads or take their vehicles off-road will see their shocks/struts deteriorate quicker than those who mostly commute on highways and city streets.

Most shocks or struts will need replacement at some point between 50,000-100,000 miles. While this isn’t a steadfast rule, you should keep a closer eye on your suspension during this time. 

How Do I Maximize the Life of My Shocks or Struts

The best way to get the most out of your shocks and struts is to protect them while driving. Driving less aggressively can help extend their life as they’ll take less of an impact around corners and over bumps. Rough roads will also accelerate the deterioration of the components, so they should be avoided if possible. 

Proper alignment is also crucial for protecting your suspension, as even a small change in the alignment can cause your shocks or struts to wear quickly.
