'Today was the first time I've driven my truck in stop n go traffic since I've replaced head gasket. Usually the gauge stays just below 1/2 , sometimes centered on the guage. Today it went to about 3/4, of course I got worried. Put the heater on, and it went down pretty quickly. Its been about 800 miles since headgasket. Re-torqued once , after initial heat cycle. The coolant has been full everytime I check it.
I haven't checked coolant today, so I will in the morning. What I'm wondering is: has anyone put the cooling fan shroud on from a truck w/ A.C. ? And did it help the temp? I am going to install a 180 thermostat. And retorque the head again. Any other ideas? Maybe I should flush the cooling system?
