yellowblue Adding Coolant If you need more coolant, add the proper DEX-COOLR coolant mixture at the surge tank, but only when the engine is cool. Power Steering Fluid The power steering fluid reservoir is located next to the engine coolant surge tank on the passenger's side of the engine. CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Don't spill coolant on a hot engine. When replacing the pressure cap, make sure it is hand-tight. When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. 6-26
