I need some help:
94 Chevy 3/4 tom 350 TBI standard.
Driving down the freeway at 70, 2200 rpm, it will heat up to 210. Slow down to 60 it will drop to about 190. Stop at a light it falls to 180. Radiator is only a couple of years old. Strange thing is it doesnt do it all the time. I pulled the grill and shroud today and washed out the condensor. I thought it may be a air flow problem. but its still doing it.
