CHASSIS CHECKING POWER STEERING FLUID If the vehicle has been driven around 80 km/h (50 mph) for 20 minutes (a little more in frigid temperatures), the fluid is hot (60_C - 80_C or 140_F - 175_F). You may also check the level when the fluid is cold (about room temperature, 10_C - 30_C or 50_F - 85_F) if the engine has not been run for about five hours. 1. Clean all dirt off the reservoir. 2. Remove the reservoir cap by turning it counterclockwise and wipe the dipstick clean. 3. Reinstall the reservoir cap. 4. Remove the reservoir cap again and look at the fluid level. If the fluid is cold, the level should be in the "COLD" range on the dipstick. Similarly, if it is hot, the fluid level should be in the "HOT" range. If the level is at the low side of either range, add automatic transmission fluid DEXRONRII or III to bring the level within the range. Check the fluid level on the dipstick. If necessary, add automatic transmission fluid DEXRONRII or III. 236
