Re: Me and my "new" 86 Coupe GT

Luis--thanks for responding.  Yours is the third reposnse, and their
sameness leads me to believe a thermostat and Techron are immediately in

However, a strange development--last night and this mornging, the temp
gauge spiked to normal several times, but only when I was pulling some
g's in right turns.  Left, nothing, and straight--cold as ice.  Oil temp

I don't want to find out from a blown gasket ot warped head that I'm air
bound and ready to pop.  Any insight?
