If you are to get the most out of your car, it is critical to engage in routine maintenance of the vehicle. While keeping a keen eye out for potential car problems as well as engaging in responsible driving practices, a few things should be handled by a professional mechanic. Some motorists may feel confident enough to take matters regarding their car into their own hands but if you do not have the right training and expertise, you could end up causing damage to some critical auto parts. Below are three types of vehicle maintenance that should be left to your mechanic. 

Repair of the transmission and engine

Two of the most intricate systems in your vehicle are the transmission and the engine. Both these systems comprise a vast assortment of components that have been precisely configured for optimum operation of your car. You may be under the impression that a minor issue with these systems can be fixed at home, but what you are not bearing in mind is that even a minor mistake can translate into the catastrophic failure of the entire system. Moreover, if you make a mistake, you could end up damaging additional components and cause your vehicle to require extensive repairs. If you are having a problem with your engine or transmission, no matter how small the issue may appear to be, it is imperative to call a mechanic immediately.

Diagnostics for the check engine light 

Your car's check engine light can come on for numerous reasons. This light can be triggered by minor issues such as a gas cap that has come loose or by major problems such as the failure of the vehicle's catalytic converter. The typical oversight that some motorists make is ignoring the check engine light under the pretence that it will eventually go off on its own. In reality, the longer you keep ignoring the check engine light, the higher the risk of experiencing a complete breakdown in the middle of the road. There is a list of diagnostics that need to be carried out to determine the underlying problem. This diagnosis should only be performed by a mechanic if you are to eliminate the risk of damage to your vehicle as well as the chance of a misdiagnosis.

Freon refilling for your auto AC

Refilling the Freon in your vehicle's air conditioning may sound simple enough but this is hardly the case. To begin with, the polyalkylene glycol that functions to lubricate the air conditioning's compressor should only be administered into the AC via specialised equipment. Secondly, if insufficient polyalkylene glycol is added to the system, it is only a matter of time before the compressor seizes and potentially combusts. Therefore, only your mechanic should perform refills.
