Component Tests Pressure Test WARNING: When releasing the cooling system pressure, cover the coolant expansion tank cap with a thick cloth to prevent the possibility of coolant scalding. Failure to follow 1. 1. Slowly remove the coolant expansion tank cap to release the cooling system pressure. 2. 2. Install the coolant expansion tank cap. 3. 3. Install the special tools 303-396 and 303-396-09 to the coolant expansion tank. 4. 4. Pressurize the cooling system to the coolant expansion tank cap release pressure. REFER to: Specifications (303-03E Engine Cooling - 2.0L Duratorq-TDCi (85kW/115PS) - DW/2.0L Duratorq-TDCi (100kW/136PS) - DW/2.0L Duratorq-TDCi 5. 5. Observe the cooling system pressure tester gauge reading for approximately two minutes. The pressure should not drop during this time. If the cooling system holds 6. 6. Check the cooling system by repeating steps 3 and 4 at least twice. 7. 7. If a coolant leak cannot be found, check the engine for cylinder leakage. Drain the cooling system. Repair any coolant leaks found and fill and bleed the cooling system Cooling System Draining, Filling and Bleeding (303-03E Engine Cooling - 2.0L Duratorq-TDCi (85kW/115PS) - DW/2.0L Duratorq-TDCi (100kW/136PS) - Duratorq-TDCi (103kW/140PS) - DW, Removal and Engine. * INSPECT the engine, cylinder head, cylinder block and cylinder head gasket.
