Fluid Inspection and Procedures

Recently, one of our customers called with concern because she had just parked her car and fluid was running out beneath her car.  She indicated she had been out of town and, upon returning, had topped off her fluids.  Now, after driving a bit, fluid was leaking.  What should she do?

The first thing Jeff instructed her to do was check to see if she had tightened the coolant cap thoroughly. If not tightly secured, when the engine runs the coolant warms up and expands, it can cause overflow.  To her relief, she had not.  A simple extra twist of the cap and all was well.

To avoid this type of situation, the following are helpful guidelines:

Recommended Fluid Inspections and Procedures

Engine oil should be checked every other fueling interval. Be sure to check with the engine off but warm to ensure an accurate level.

If you have to add oil, be sure to put the cap in a place you won’t miss to reinstall.  Many caps are left on gas pumps only to be realized later when you notice excessive engine noise or a burning odor.

Transmission fluid should be checked once a month. The engine should be warm and the vehicle running in park.

Clean the dipstick numerous times and reinsert to ensure an accurate reading.  The labeling on the dipstick is marked as “warm or cold” and only add fluid if the level is below the cold line.

Power steering fluid should be checked if you experience excessive noise or whining when turning the steering wheel, as your fluid is probably low. The engine should be off.

Visually inspect the reservoir to identify if the full or low markings are labeled on the reservoir or if your vehicle is equipped with a level indicator dipstick. If you have a dipstick, this too will have a cold or warm marking. Only add fluid if it is below the cold line.

Engine coolant, or anti-freeze, is normally checked at oil change intervals.  However, if leakage is observed, all fluids should be checked immediately.  Be very careful never to check your engine coolant if the engine is warm.

If you experience high engine operating temperature or poor heat output, your coolant could be low. All vehicle cooling systems are designed differently.  Some are equipped with an over-flow reservoir, which is a good way to add coolant and monitor if the coolant level changes. However, removing the radiator cap is the most effective.  As mentioned above, be sure to fully install the pressure cap when finished adding or checking your level to avoid boiling over.

Not everyone wants to monitor their vehicle’s fluids; however, if any warning indicator lights come on, you should act promptly.  Ignoring warning lights can lead down a bumpy road.  When you have your vehicle in for its regular maintenance, these various fluids are also checked.
