I am having troubles with fluids in places they shouldn't be and the engine is over heating.

The relay is in the relay box on the right front inner fender panel. i attached the coolant sensor locations in diagrams for both the 2.3L and 2.5L and files are labeld with 2_3 and 2_5.
The PCV valve is on the valve cover and the hose runs near the right rear of the engine bay, so you could use that to trace it if you have trouble.
