Pinpoint Tests A: Loss of Coolant: Notes

Normal Operation -  The supercharger (SC) cooling system is a closed system that provides for coolant expansion and contraction and also changes in pressure as coolant warms and cools with the engine operation. Various gaskets, seals, hoses and clamps are used to contain coolant within the cooling system and keep other fluids and contaminants from entering the cooling system.

Coolant loss can be attributed to either external or internal leaks anywhere within the cooling system.

For vehicle/engine specific information, refer to Supercharger Cooling .

This pinpoint test is intended to diagnose the following:

• Pressure relief cap
• Degas bottle
• Charge air cooler (CAC)
• Radiator
• Coolant pump
• Coolant hoses
