Engine Cooling: Diagnosis Jaguar S-type I рестайлинг

Supercharger Cooling - Diagnostic Procedures

1. Verify the customer concern by operating the system.
2. Visually inspect for obvious signs of mechanical and electrical damage. Visual Inspection Chart Mechanical Electrical Leak(s) Hose(s) Charge air cooler radiator Supercharger cooling water pump Coolant expansion tank Coolant pressure cap Radiator Engine cooling water pump Cooling fan Fuse(S) Wiring harness Electrical connector(S) Engine coolant temperature sensor Cooling fan motor Supercharger cooling water pump
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the cause is not visually evident, verify the symptom and refer to the Jaguar Approved Diagnostic System.
