running hot right after starting engine
Ok, so the stat is working , you have a shroud and a clutch fan that works too. a few things i would check is the distance between the rad. and fan, if the motor is running lean, timing, and also feel for hot and cold spots on the radiator in case it is blocked up. even new radiators have been known to be defective. also give us a rundown of the motor setup and if you have a few pics so we can see what you have that might help too.
