Hi Guys,

Just wondering if anyone can shed some light on my problem.
Just recently (few months ago), I had my radiator and thermostat changed because my engine was overheating (reaching 100 - 105).
But now this problem has seemed to come back. It is currently hitting summer here in Australia, and I notice that the Oil Temp (the one on the bottom left) goes up to 100-110 after say 15mins drive, then up goes my engine temp (100 - 105) as well. When I start to drive, it goes down a little.
Is this normal?? And if not, what else can be the problem?? Can it be the coolant pipes clogging and not letting the coolant through efficiently?? Or anything else??
It's been an ongoing saga and I'm about to throw in the towel but I love my car.

Oh.... it can't be the air-con unit can it??
I know I have a leak somewhere, but I don't think that would cause the car to heat up so much??

Thanks in advance

 

Are the needles going past straight up? (I don't remember where the temps are at straight up.

With your admission that the temps fall when you are at speed, it seems like there could be a lack of air through the radiator. look for a blockage, like a piece of paper in front of any heat exchangers in the grille area. Check to make sure the radiator fans (both the mechanical one run off the belt and the electric with the AC on) run. If the clutch has quit, the AC fan is not working or any of that, you have your first issue. Second, I would look at doing a leak down and checking the head gasket from your previous overheating episode.
