Performing a complete fluid check on your car is one of the simplest yet most important maintenance tasks you can do

First, find a flat, even area to park and shut down the engine

Allow the engine to cool for 5–10 minutes to ensure accurate fluid readings

Find each fluid container and dipstick under the hood—consult your manual if unsure

Begin with the engine oil level

Remove the dipstick, wipe off any residue with a lint-free cloth, fully reinsert it, and withdraw it once more

Look at the level between the minimum and maximum marks

The oil should also look clear and amber, not dark or gritty

Never use generic oil—always match the exact grade and type recommended by the manufacturer

Move on to evaluating your engine coolant

Always check the expansion tank, not the radiator—only open the radiator if the engine is completely cool

The fluid should be between the cold and hot fill lines

Always wait until the engine is fully cooled before touching the radiator cap

If it’s below the line, refill with a 50

Now check the brake fluid

It’s commonly located on the driver’s side near the back of the engine bay

The fluid should be clear and at the full mark

If it’s low, it could indicate a leak or worn brake pads, so have it inspected

Warm up the transmission by idling the engine while in park

Wipe the stick clean, reinsert it completely, then pull it out again to assess both position and appearance

It must not appear dark brown or emit a burnt smell—this signals degradation

If the fluid is black or اتوسرویس داوود smells like burning plastic, a fluid and filter change is overdue

Don’t forget the power steering reservoir if your car is equipped with it

It’s usually marked "Power Steering" and may include min

Top off if needed with the correct fluid

Don’t overlook the windshield washer fluid

Simply glance at the tank and refill when the level is near empty

Choose a solution rated for your region’s lowest expected temperature

Make sure every reservoir lid and dipstick is fully seated to prevent leaks

Keep a record of your checks and any fluid you add

Regular monthly fluid checks prevent costly repairs and significantly boost your car’s longevity
