Jim, what I dont understand is that, lets say it is the head gasket. But when the dual aux fans come on, the coolant in the radiator should be cooled right away? No? And if thats correct, when the coolant makes it's way back into the engine block it should bring the temps down. How is it possible for the temp to just keep rising....even with the fans on? It just doesnt make sense. Leads me to believe that it could have something to do with the radiator not performing the way its suppose to. All I can recall is that, when I bought the car it would overheat, not boil over tho.... Then I changed the coolant and replaced my aux electric fans, I had the car working fine. It would heat up to 105 degrees then the fans would kick in then the temps would come down. I could spend hours in rush hour traffic.

Then one day I decided to remove the condenser and aux fan assembly, so that I could sand down and paint the aux fan assembly/frame. Because it was beginning to rust in some spots. Anyways when I re-assembled the system, it didnt worked like it used to. Dont know what has happened.


BTW, I see some oil residue in the area indicated in the picture attached (circled area). This is on the left side of the engine, below the valve cover, around the area where there is a large hexagonal shaped indentation in a raised round metal surface (thats the best way I can describe it). I always see oil residue here.... I can touch it and smell that its oil. I am sure oil is leaking out of here.


There is no sign of oil in my coolant, and no sign of coolant/water in my oil.
