This article is a continuation of last month's article on whether today's vehicles are really maintenance free. We talked about engine oil but it is just one of the many fluids in your vehicle. Engine oil and transmission fluid lubricate the 2 most important and expensive components of your vehicle, the engine and transmission.

The automotive industry standard is to replace transmission fluid at minimum every 30,000 miles. Transmission specialists are going to tell you to replace fluid every 20,000 miles. Transmission fluid is full of detergent and like engine oil, it is designed to clean, cool and lubricate. Dirty fluid has suspended particulate in it that can be abrasive and accelerate the wear of the transmission.

Coolant is designed to keep the engine cool. It provides higher boiling and lower freezing points as well as lubricating the engine water pump and has corrosion inhibitors to help reduce corrosion in the coolant passages of the engine. Coolant can become acidic if it is allowed to age and can actually do damage. The acidity can eat away at hoses, gaskets and even metal overtime. Keeping coolant changed regularly keeps it clean, at the proper protection level and at the proper pH balance for the best results. The industry standard is to flush the coolant every 2 years or 30,000 miles.

If you want your vehicle to last more than 100,000 miles, then it is not maintenance free! Regular maintenance can add longevity, reliability, and value to your vehicle. We recommend consulting with your trusted repair facility for the best way to maintain your vehicle. Happy Motoring!
