Changing Vehicle Fluids

Q: My owner’s manual recommends changing the fluids of my vehicle (such as the antifreeze and transmission fluid). Why is this necessary, and how often does it really need to be done?

A: We also recommend regular maintenance to your vehicle. Changing and maintaining fluids is one way. Just as people need to have their systems checked and maintained as they grow older, so do cars. During the regular use of your vehicle, the fluids that protect critical components wear out, causing unneeded corrosion and damage.  Harmful deposits sneak in and steal the life from your vehicle.

Allowing the dirty fluid to run through your vehicle can lead to serious problems in the future. Dirty transmission fluids can actually ruin internal transmission components. Old, broken down coolant can form into a phosphate scale that can coat the entire cooling system. This can lead to radiator or water pump failure.

There have been many advances in the fluid change service. It is always best to have a professional perform these services. Most of the time, this can be done without disassembly of the vehicle.

During your routine oil change visits to your repair facility, all fluids and filters should be checked regularly. Some fluids can be affected by your driving patterns and habits. Most manufacturers recommend fluid changes every 36 months. However, if your fluids show signs of excessive break down, you may need to change them sooner.
