SERVICE PROCEDURE:
1. Raise vehicle up on hoist.
2. Depress locking tabs on plastic snap-in connector on oil cooler outlet hose and pipe assembly.
3. Brace pipe assembly with one hand to prevent bending or damage and pull hose assembly off of snap-in connector with other hand. Some leakage will occur, but it will be minor. The snap-in connector will come out with the pipe assembly.
4. Check snap-in connector and "O" ring inside of hose assembly for damage. If no damage is evident, lube male tube end surface, up to the head, with engine oil and snap the connector onto the pipe tube and making sure it is properly seated before reconnecting the pipe to the hose assembly.
