Your vehicle depends on several types of fluids to keep things operating. They have a “useful” lifespan and need replacement once they’ve exceeded this threshold. Many people know that they need to get their oil changed, but they may overlook service for other fluids. If they don’t get checked and changed as needed, the vehicle could have parts and system failures.


Oil is necessary for a car engine to operate. It lubricates the components and reduces how much friction is caused when the parts move.  Oil is the fluid that gets changed most often in any vehicle.  Oil breaks down over time, and the oil filter, which traps contaminants from inside your engine, can only hold so much.  The typical oil change is recommended every 3,000 to 5,000 miles, although it may be higher for synthetic oil.  The exact replacement rate is based on the specific requirements for that vehicle.


The engine in your vehicle generates a lot of heat when it operates.  It relies on coolant in the radiator to keep it cool.  Special chemicals in the coolant not only keep the engine cool, they lubricate the cooling system on the inside.  With time and wear, those chemicals can no longer protect your cooling system.  The coolant has to be refreshed by replacing it.  Your coolant should be flushed every 30,000 Miles, or if you are using Extended Life Coolant, you can go 60,000 Miles.

Brake Fluid

Brake fluid lubricates the brake system on the inside so that it works smoothly.  This fluid is also hydroscopic, which means it absorbs moisture.  This protects the inside of your brake system.  On all modern vehicles, as the brakes wear down, it will cause the fluid level to drop.  You should have your brake fluid inspected periodically, and we recommend replacing the fluid every 30,000 Miles, or at the time of your next brake replacement.

Transmission Fluid

Transmission fluids lubricate the transmission so that shifting is smooth.  In an automatic transmission, the fluid also helps keep the transmission cool by flowing through cooler lines.  Low fluid can cause shifting problems.  Some vehicles do not have a dipstick to check the fluid, so have your vehicle inspected periodically by a knowledgeable mechanic.  We recommend replacing transmission fluid every 60,000 Miles.

Power Steering Fluid

The power steering system also uses fluid. This fluid also not only lubricates, but protects the inside of your power steering system. This fluid level can be checked by looking at the power steering fluid reservoir.  It should be full.
