How to Check Engine Fluids 02-06 Nissan Altima
Difficulty: Beginner · About 25 min · Nissan Altima
Inspect the brake, automatic transmission, engine oil, power steering, and coolant levels on a 2002–2006 Nissan Altima, using the correct operating conditions for each check.
Tools you will need
- Flashlight
- Brake fluid
- Transmission fluid
- Engine oil
- Power steering fluid
- Coolant
Steps
- Check brake fluid
Inspect the brake reservoir and confirm its level sits between the marked limits. The fluid should be clear or light in color; dark or murky fluid needs service rather than a simple top-up.
- Check transmission fluid
Bring the transmission to the required operating condition specified in the owner's manual. With the vehicle secured, follow the manual's procedure for cycling gears and reading the dipstick, then add only the specified fluid if needed.
- Read engine oil level
On level ground with the engine off, wipe the oil dipstick clean, seat it fully, then withdraw it to read the level. Add the correct oil in small amounts if the mark is below range.
- Inspect power steering fluid
Check the reservoir level against its marks and note the fluid's condition. A burnt odor or dirty appearance should be investigated and serviced with the correct fluid.
- Inspect coolant when cold
Allow the engine to cool before checking the coolant reservoir, and keep clear of any hot pressurized system. Confirm the level is within the cold range and secure the cap afterward.
Check your vehicle’s repair manual for exact specifications and fit.
