Thinking about saving some money and doing your car repairs? That’s a great idea if you know what you’re doing. Unfortunately, many do-it-yourselfers don’t, and that’s why it can be dangerous to perform car repairs on your own. When done improperly, car repairs can lead to serious safety risks like impaired visibility, functionality issues, or engine failure. Even minor repairs can have significant consequences if you aren’t prepared for them. Here are some car repairs you should never do yourself.
Engine diagnostics
A good mechanic will always start with an engine diagnostics test to ensure everything is in proper working order before moving forward with repairs. Engine problems are challenging to detect and often require a mechanic to pinpoint the issue, so if you smell something burning, hear strange noise, or notice any other strange happenings, it’s best to leave engine repairs to the pros. If a car’s engine isn’t operating as it should, it can cause several other problems, like poor transmission functionality or even airbags that don’t work. While you may be able to detect and fix a few issues on your own, an engine diagnostics test is impossible.
Timing belt
The timing belt is a critical part of your engine that keeps running smoothly and safely. If you have a vehicle with a timing belt, you should change the belt at the specified intervals to avoid catastrophic engine failure. When the belt breaks, you can’t simply replace it with a new one. You need to reset the engine’s timing and ensure everything is lining up correctly with the belt replacement. Doing this incorrectly can cause serious damage to other parts of the engine, including the valves and pistons. Changing the timing belt is a job best left to experts.
Head gasket
The head gasket seals the engine block and the cylinder head together, creating a barrier between the gas in the cylinders and the coolant in the radiator. A Subaru head gasket repair often comes with a hefty price tag. With a used engine, the head gasket is a ticking time bomb. It can fail at any time, causing serious engine damage that would cost you even more. If you overheat the engine, the head gasket can fail within minutes. Cracking the engine block open to replace the gasket is dangerous for an amateur and can cause severe damage to the rest of the engine. While it’s a very common repair, you need to know what to look for when diagnosing a head gasket failure.
Fuel pump
The fuel pump is what delivers fuel to your engine. If it isn’t working correctly, it can cause the engine to stall, run poorly, or not start at all. A fuel pump isn’t easy to replace on your own, and the process can be messy and challenging. The best way to diagnose and replace a faulty fuel pump is to enlist the help of a mechanic. If you have no idea if your fuel pump is defective, it’s best to have a professional assess the situation to prevent potential engine damage related to a faulty pump.
New windshield installation
Safety and functionality. The windshield is a critical part of your car’s safety system, as it shields you from debris, insects, and harmful UV rays. If a rock or giant bug flies up and breaks your windshield, it isn’t something you should attempt to fix yourself. Why? First, you need to find a suitable windshield model for your car; then, you need to measure your vehicle and the windshield to make sure it fits correctly. Even if you get the measurements correct, you’re unlikely to install the windshield properly. Most car owners don’t have the right equipment to install the windshield correctly, so if you try to do the job improperly, it could cause the new windshield to fog up.
