When you think of expensive car repairs, replacing the transmission probably pops into your mind pretty quickly. That’s not surprising since it can cost you a few thousand dollars, according to the Transmission Cost Repair Guide. Without the transmission, though, your car can’t move. It helps your engine run smoothly and transmits power from the engine to the wheels.

In order to keep your transmission working properly and to avoid having to replace it entirely, it’s important to keep up with regular maintenance. Transmission fluid should be checked monthly. The fluid needs to be kept at the right level and replace the fluid as needed. You should also avoid aggressive driving and riding the brakes.

The head gasket keeps coolant from mixing in with the engine oil. If it cracks, this mixture can damage your engine. The repair could set you back a couple of thousand dollars, so you’ll want to take measures to avoid this from happening.

The head gasket can crack if the engine overheats. You may also have a cracked head gasket if your oil is white like milk, if there’s a coolant loss with no visible leak, if there’s smoke coming from the tailpipe, or if there are bubbles in the coolant overflow tank or radiator, according to Advance Auto Parts. To prevent a cracked head gasket repair, check your coolant regularly and change it when needed and replace worn hoses and belts.

This car part should last for as long as your vehicle does, but it can get damaged if you use the wrong oil, the engine burns oil, or you drive over something too quickly like a large speed bump. To avoid having the catalytic converter replaced, make sure to drive carefully over speed bumps, use the correct oil for your vehicle, and change your oil regularly.

The timing belt connects your vehicle’s crankshaft to the base of the engine to ensure the valves open and close properly. As you can imagine, this car part goes through a lot of wear and tear, and having the timing belt break is a big problem. If the belt breaks or snaps, it can lead to engine damage.

The best way to avoid this costly repair is to have your timing belt replaced according to your vehicle manufacturer’s recommended schedule.

5 Fuel Injector Replacement

Fuel injectors spray a fine mist of gas to the combustion chamber, allowing the correct amount of gas to be delivered to the engine. Each cylinder has a corresponding fuel injector, so a four-cylinder engine has four fuel injectors. A replacement can cost you between several hundred to a few thousand dollars.

You might have an issue if your check engine light comes on, your engine misfires, you have a fuel leakage, you smell gas, or you’re getting poor gas mileage. While fuel injectors to wear out eventually and require replacement, it’s possible to extend the life of these car parts with regular maintenance. You should have the fuel injectors cleaned according to the recommended service schedule.

4 Engine Seizure

There are many reasons your engine could seize, and, if this happens, you might have to buy a new engine or an entirely new car. It makes sense, then, that you’d want to avoid this! When the engine seizes, the crankshaft won’t turn and is frozen. This can happen if your engine overheats or you’re running on little to no oil.

If your oil light or engine temperature light comes on, stop driving immediately, turn off your car, and have it towed to a nearby garage. To prevent an engine seizure, be sure to get regular oil changes using the correct oil for your vehicle. Check oil levels each month, and top it off when needed. It’s also a good idea to have your cooling system serviced regularly.

3 Tire Replacement

You know that the tires of your vehicle will need to be replaced eventually, but repairs and replacements can become very expensive over time if you don’t properly maintain your tires. Make sure that your tires are always inflated to the correct level and that the tread hasn’t worn down too low.

It’s also a good idea to get your tires rotated regularly, and a good rule of thumb is to have this done when you get your oil changed to ensure that the tires wear evenly. If your tires wear unevenly or you cause extra damage with hard braking, you’ll need to replace your tires more often, which can really add up in costs.

The camshaft is a component of your engine’s internal combustion system. It opens and closes the engine valves and controls the flow of air into the engine. When an issue develops with the camshaft that goes unchecked, it can affect your vehicle’s performance and do more damage to the engine.

This can lead to a repair that costs a few thousand dollars. The good news is that a camshaft replacement is preventable if you get your oil changed regularly and you have your cams adjusted occasionally. It’s also helpful to use the correct gas for your vehicle. If your car requires premium, make sure to use that instead of regular unleaded.
