Five Fluids You Can Check Yourself

Modern cars need less hands-on maintenance than older ones, but checking fluid levels regularly remains one of the simplest ways to prevent problems.

Always check your owner's manual for the correct procedure and fluid specifications for your car.

Engine oil

With the car on level ground and the engine off, pull the dipstick, wipe it, reinsert it fully, and pull it out again. The level should be between the minimum and maximum marks. Some cars have electronic oil level displays instead.

Coolant

Check the expansion tank when the engine is cold. The level should be between the marks. Never open the cap when hot.

Brake fluid

The reservoir is usually translucent with minimum and maximum marks. A falling level may indicate worn pads or a leak and should be checked by a professional.

Windscreen washer fluid

Top up with a suitable washer fluid, using a winter mix in freezing conditions.

Power steering fluid

Many modern cars have electric power steering with no fluid. If yours has a reservoir, check it according to the manual.

What to watch for

▸Levels that drop between checks
▸Puddles under the car
▸Milky oil or oily coolant, which can signal serious engine problems
