Not Ranked
Now have 800 miles on Superformance/KC 408 engine. I’m still experiencing sporadic short-term overheating. The gauge temporarily spikes under optimal conditions (like steady 45 mph cruise), and then comes right back down to normal within a couple minutes.
Will go get a new thermostat and surge/expansion tank cap.
What temp thermostat…180?
What pressure expansion tank cap…13 psi?
