Car running hotter than it should..

Mike just try changing the water pump pulleys. Its four stupit bolts, Try that first and if it does not work then do the rad. I had the same problem when I had my under drive water pump pulley. It was fine for just sitting there but once I got going the temp would just start to climb. Rember the under drive pulleys turns everything slower. so even at higher rpms it is still turning the water pump slower then what it would be with a stock water pump pulley. Just try & prove me wrong

Do you have the plastic air deflector on the car. If not put one on it will make a hudge diffrence when the car is moveing.

Is your radiator a 3 core copper/brass radiator? I have a 3 core Ford Motorsport copper/brass radiator and never had a problem with it until I installed an electric fan and now I will not stay cool in the warm weather. I have friends with the same fan I have and they are running a 2-core aluminum radiator. There cars actually run too cool. I just ordered a griffin aluminum radiator from summit yesterday and may change fans to see if this will help. Mine was creeping up around 210 yesterday in traffic with a 180 degree thermostat.

If you still have a/c, which I doubt, you can seal up the gap between the condenser and radiator. That will force the fan to pull more air across both of them, providing greater cooling efficiency. I am not a believer in the water wetter. I ran some in my car, and in my dads t-bird when they were getting a little hot. My stang was only heating up in traffic with the A/C running. The bird was heating up on extended hwy trips. Believe it or not, a new fan clutch fixed the bird, and a 3-core rad helped the stang. I put a taurus elec. fan in the stang and that did it. Thats just my experience, your car is very different. Our cars are mostly stock. Another new 3-core may do nothing for you, unless your present one is clogged. I dont think they will cover a clogged radiator under warranty. I will tell you, in case you didnt know this. Flush your cooling system before you put in another rad. I will also second, the go for an alum. rad. advice. And look for the highest fin per inch count. Your car is making alot of power, and with that comes alot of heat. Thats my .02. good luck to you.

Thats where I got my 3-core too.

I went ahead and ordered a Ramchargers fan also. Hopefully no more cooling problems.

having the same prob with my 95 3.8 bit ch, just finished a headgasket job, it seamed to run a bit on the warm side like RM when it hits M the fan kicks on, on a run she runs R,the gauge moves to dam much for my liking.

Glad someone else in this damn world has the same problem I do. I've done all the stuff, and my car does the same thing. The only way I can get the car to run where I'm comfortable with it is when I pull the stat completely out, and replaceit with a restirctor plate. When it's cold the car seems to run a wee bit hotter than it should, but in the summer, I'm blasting the heat! OH YEAH!!! I've pulled evr thing out in front of the radiator, tried new radiators, and short of swapping over to an aluminium unit, I'm stumped. Car's fast and all, but I noticed the problem began when I swapped on my AFR's on the LAST car. New block, all rebuilt, and same problem, in a totally new car.
