Thread: Engine Coolant Temp Fluctuating

you are using the bleeder screw on top of the t-stat housing right?

i leave the rad cap off, let the car idle till the fans come on, that way you know the t-stat opened up, top off rad if needed, loosen the bleeder screw, keep open till a stream of coolant comes out, shut screw, top off rad, cap it.

That's pretty much what I did the first time i did it. Maybe I'm opening up the screw too early. I'll try it out tomorrow with keeping the screw tightened till the fans kick on. See how that works.
