Thanks for the replys. First I use the Laser on the radiator, manifold in several spots, the thermostat housing. Even after extended driving over 35 miles the temp still goes from 110 to 180. When it reaches 180 it drops fairly fast to 110. I am going to the dealer today to get a GM thermostat and see if that will help. It seems that the thermostat opens fully when at normal operating temp of 180 but does not close until it reaches 110. Since this has happened with two new thermostats I have been thinking it may be the brand of thermostat.
