Why Would a Blown Head Gasket Cause Overheating?

The coolant in your vehicle’s engine serves an important purpose: it removes heat from your engine. This heat is created during the combustion process, as your engine fires and ignites the fuel and air mixture that makes the pistons move up and down. Some early engines didn’t have coolant and instead relied on air to cool the engine. Modern engines are much more high-performance than traditional air-cooled engines and require efficient cooling systems to keep them running at the right temperatures.

Your head gasket is an important component in your cooling system. It not only creates a seal between your engine block and head, it also channels coolant for optimal engine cooling. A blown head gasket can…

Is it Safe to Drive with a Blown Head Gasket?

The quick answer? No! A blown head gasket is a major problem for any engine, and one that costs quite a bit to fix mechanically. The head gasket is responsible for creating a seal between your engine block (the lower portion that houses the cylinders) and the head (the upper portion that contains the valves). Your head gasket also acts to channel engine coolant to keep your engine cool during operation. A blown or cracked head gasket can cause one of two problems:

It can allow coolant to escape from your engine. The result is a loss in coolant, which can lead to overheating of your engine if you drive it for any length of time.…

Why is my Car Leaking Oil When the Engine is Cold?

It’s easy to assume that engine oil leaks will be more prevalent when the engine is running. When an engine is running, oil pressure increases, which makes it more likely that engine oil will leak. Quite often, however, we can see engine oil leaks that occur when a vehicle is parked and the engine is cold. Here’s why.

When your engine is hot, the block, head and other metallic components expand. This expansion can force components closer, squeeze gaskets and seals tighter and create a seal that effectively prevents oil from leaking. When you turn off your engine and it starts to cool down, the metals contract, which can open gaps between seals and mating components. The…

Why is my Car Leaking Oil When Parked on a Hill?

Depending on the cause and location of an engine oil leak, you may not detect it all the time. Sometimes an oil leak will only present itself when you’re parked on an incline. Even if this kind of leak doesn’t appear all the time, you need to take action once you notice it. Any engine oil leak means you’re losing oil and you risk running your engine without enough oil for lubrication and cooling. Oil leaks are bad, and we’ve seen what happens when they’re ignored for too long. Hint: nothing good.

If you only notice an engine oil leak when you’re parked in an incline, it might be because:

Your engine oil leak is on one…

Where is my Power Steering Fluid Leaking From?

Power steering fluid leaks are relatively common on older cars. Power steering leaks often start small and only occur when you’re driving your car, so they’re often difficult to detect. You don’t always get a noticeable puddle on your garage floor like you do with other automotive fluid leaks, which is why it’s important to check your power steering fluid level on a regular basis and watch for a drop in the fluid level.

But aside from puddles and other visual evidence that something is wrong with your power steering system, there are some telltale signs that you have a power steering fluid leak:

A noticeable drop in the level of fluid in the reservoir
A difference in feel when steering your car, especially at…
