Pardon my curiousity.... but where do you drill the hole...???
I have the same thermostat issue.... what they came up with is too small for my truck......but I have the old big one to compare.... so it's back to the store....
So the hole... is it drilled in the skirt of the new large thermostat..... because the newer ones are tighter sealing when cold...???
Thanks for your help and advice.
