6. Inspect color and smell. On a 2020 Subaru Forester, oil should be amber to dark brown, not thick black or smelling burnt.

What to do if it is low: Add the correct oil type listed in your 2020 Subaru Forester’s manual, a little at a time, then recheck. If you are adding oil often, you may have a leak or burning issue that needs a mechanic.

2. Locate the coolant reservoir. It is a translucent plastic tank near the radiator with “MIN” and “MAX” marks.
3. Check the level visually. The coolant in your 2020 Malibu should sit between the marks.

If coolant is low: Top up with the correct coolant type recommended for your 2020 Subaru Forester. Never open the radiator cap when hot. If you frequently add coolant, you may have a leak or head gasket issue and should see a shop.

3. Pull, wipe, reinsert, and check. Fluid should be within the marked range and a reddish color, not dark brown or burnt-smelling.

If your 2020 Subaru Forester dipstick, leave transmission checks and fluid changes to a professional. If you feel slipping, harsh shifts, or low power, combine this with the advice in the Beginner’s Guide to the Most Common OBD2 Trouble Codes to see if a code is stored.

4. Brake Fluid and Power Steering (If Equipped)

On a 2020 Subaru Forester, brake fluid and (if your trim has hydraulic power steering) power steering fluid are also critical.
