Many people who are good with tools enjoy saving money by taking care of basic auto repair and maintenance tasks themselves. If you can change your own oil or top off the antifreeze, by all means do so. However, some tasks are beyond the scope of DIY enthusiasts. Below are some of the key maintenance and auto repair jobs you should always leave to professionals.

3 Car Maintenance Jobs That Should Be Left to Mechanics

1. Charging A/C with Freon™

Freon is available at most hardware and auto parts stores, and if you know how, you can refill your air conditioning system and get it blowing cold air again. However, the problem is the leak itself. The refrigerant lines are meant to be a closed loop, not to be refilled occasionally. New Freon will just leak out again, and you'll be back to no cold air.

2. Replacing the Timing Belt

The timing belt synchronizes the rotation of two different shafts in the engine, the crankshaft and camshaft, to ensure the intake and exhaust valves open at the right time. It needs replacement every 50,000 to 60,000 miles. Not only does it take special tools to remove the old part, but the replacement parts are also expensive. You risk engine damage if you install the new belt improperly, so leave this job to a professional.

3. Interpreting Diagnostics

Although engine diagnostics tools are available at parts stores, the "check engine" codes they disclose may not tell you much. For instance, the diagnostics code may tell you where the problem is, but not what it is, or it may suggest several potential problems. Mechanics often conduct more investigation using other equipment to learn what's wrong with the vehicle.
