Cooling System Schematic

[MOSHO92]

Does anyone have a hose schematic for the 3.0 cooling system. Preferably with part numbers? I need to find a ghost leak from somewhere deep in the driver's side engine compartment.

Thanks

The only hoses that I can think of on the driver's side are the upper coolant hose and the couple of hoses that go to and from the throttle body and IAB valve. There is also a coolant return hose to the water pump that goes in between the V of the engine block. The cooling system really isn't all that complicated outside the engine (at least from what I know of it).

The only problem I had was not getting the upper coolant hose tight enough around the thermostat housing. There is also potential to have leaks around the ECT Sensor where is screws into the housing before the return hose. It is hard to see this area with the air intake hoses attached. You might take the intake hoses off to get a better view of this area.

Best of luck in finding your problem. When you find the problem a local auto parts store should be able to get you the correct part or at least sell you some generic coolant hoses (as would be the case for the smaller TB hoses and such).

To find the leak, drop by AutoZone and get a cooling system pressure tester for a $90 or so deposit.
