B1: coolant test

WARNING: The cooling system is under pressure! Do not release the reservoir cap until the system has cooled down. Failure to follow these instructions may result in personal injury.

Check the level and condition of the coolant. Has sufficient coolant been added to the system?

Yes - GO to B2. No - If necessary, add the prescribed coolant to the cooling system to bring it up to the correct level. For more information, please refer to: Specifications (303-03A Engine Cooling - 3.2L NA - I6, Specifications) / Drain / fill coolant and remove air from the cooling system (303-03A Engine Cooling - 3.2L NA - I6, General Procedures). Check for lack of coolant Go to PINPOINT TEST A.
