Pontiac 2006 manual Checking Coolant, Adding Coolant

If you have to add coolant more than four times a year, have your dealer check your cooling system.

Notice: If you use extra inhibitors and/or additives in your vehicle’s cooling system, you could damage your vehicle. Use only the proper mixture of the engine coolant listed in this manual for

the cooling system. See Part D: Recommended Fluids and Lubricants on page 6-19for more information.

Checking Coolant

The vehicle must be on a level surface. When your engine is cold, the coolant level should be at LOW, or a little higher. When your engine is warm, the level should be up to FULL, or a little higher.

See Engine Compartment Overview on page 5-12 for the location of the coolant recovery tank.

Adding Coolant

If you need more coolant, add the proper DEX-COOL®coolant mixture at the coolant recovery tank, but be careful not to spill it.

{CAUTION:

Turning the radiator pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. With the coolant recovery tank, you will almost never have to add coolant at the radiator. Never turn the radiator pressure cap — even a little — when the engine and radiator are hot.

{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. Do not spill coolant on a hot engine.

Occasionally check the coolant level in the radiator. For information on how to add coolant to the radiator,

see Cooling System on page 5-30.
