The Five Key Fluids
Engine Oil
Check monthly. Look for the proper level and a clean amber color. Inland Empire heat can degrade oil faster, so keep an eye on it between changes.
Coolant
Essential for Inland Empire summers. Check the level when the engine is cool. It should be a bright green or orange color.
Brake Fluid
Safety critical. If your pedal feels spongy, the fluid may be low or contaminated. Have it checked professionally rather than guessing.
Transmission Fluid
Key for smooth shifting in the stop-and-go traffic on Foothill Blvd. Red fluid is healthy; a brown color or burnt smell means it's time for transmission service.
Power Steering Fluid
Low fluid causes stiff steering and whining noises. It's easy to overlook, so make a point of checking it during routine maintenance.
