Vital Fluids Wear Out
Coolant - Wears out over time from rust and scale deposits that build up over time. This build up changes the coolant's chemical properties. These changes can cause the coolant to go from protecting the cooling systems' components to damaging your radiator and reducing the life of the water pump.
Transmission Fluid – Transmission fluid is an oil, and is subject to viscosity breakdown and the loss of its protective, lubricating, and cooling properties. Operating the transmission on that is worn out results in premature wear and ultimately failure.
Power Steering – Contamination by metal flakes and damage from overheating reduces the protective properties of the fluid. The sooner the cause of the contaminates is identified the lower the cost of repair
Brake Fluid – Brake fluid is hydroscopic in nature, meaning that it absorbs moisture which reduces the effectiveness of the fluid leading to premature brake failure.
When was the last time you had your fluids checked for anything more than they were at the right level?
