I am not sure if it ever had this problem. I bought the car in late fall and the temp was already in the 50s and it needed some brake work. It never ran warm in those temps. I first noticed it when we got an 88 degree day. I want to be able to drive it in the summer temps and not worry. No I haven't changed anything on it besides fixing the brakes.

I used to run a 180 t stat and then I took it out to see if it would make a difference and it runs a little cooler without the t stat but not much at all. Right now it has no t stat.

I know it runs a little lean and I want to richen it up but I am not sure if I will need new jets to do that or if the idle mixtures screws can richen it enough.

Yes I have a picture somewhere of the fan and the shroud. I will post it.

Is a 6 inch water pump pulley ok or is it too big? It sat for about 2 - 3 months before I fixed the brakes.

THanks.
