When Should you Not DIY Auto Repair?

When Should you Not DIY Auto Repair?

There are hundreds of DIY car repair videos that can inspire you to do some simple fixes on your own. Car maintenance and repairs are costly, and performing some repairs yourself can save a few hundred dollars. But you need to be careful with certain car repairs. Today’s cars are complicated and things are more complex than simple nuts and bolts. If you are not careful, you might damage the part you’re trying to fix, causing more damage and costing you more money. Here are some car repairs that you should never attempt on your own.

Electrical Repairs

If there are any problems related to the lights or electrical systems, take the car to an auto electrician. Computers control the lights and electrical components of modern cars. There are hundreds of sensors, connectors, and electrical wires to keep track of. Without proper knowledge, you are more likely to damage sensors that can be expensive to replace. Stay away from electrical repairs in your car.

Engine Diagnostics

Most cars have computer controlled engines. The built-in engine diagnostics constantly checks the health of your car’s engine and gives a warning if anything needs attention. The “Check Engine” light warns the driver of a problem with the engine. If you see the “Check Engine” light glowing, take the car to a mechanic. You need advanced diagnostic tools, and this problem cannot be fixed at home. Many people buy error code readers and think they can diagnose and fix the problem on their own. You need an ASE certified technician to diagnose the engine problem and perform repairs. Engine diagnostics need special equipment to find the root of the problem and fix it.

Radiator Replacement

Radiator replacement is not a DIY job. Removing the screws and bolts holding the radiator in place is not enough. Several hoses are connected to the radiator. If you are not careful enough, you could break or damage these hoses. If the connections between engine and radiator are not secure, the coolant may leak and cause the engine to overheat. If the radiator replacement is not done correctly, your engine could explode. Do not attempt radiator replacement on your own.

Fuel System Repairs

In newer cars, the fuel pump is installed inside the fuel tank. This can be difficult to remove. The fuel pump is a piece of delicate and precise equipment that needs to be handled carefully. If you make a mistake while repairing the fuel pump, it will lead to catastrophic failure of the engine. Fuel system repairs are not DIY tasks. There are so many components to take care of, like the fuel pump, fuel injectors, and fuel lines. The fuel pressure readings also need to conform to manufacturer specifications. The fuel system repair is a task better handled by an experienced mechanic.

You can learn about mechanics from car reading manuals and videos, but there is no replacement for years of hands-on knowledge and training. An auto mechanic has the ability to diagnose the problem and resolve the issue without creating a mess.
