77 overheating vette
by: Auto Appraiser * Ned

this is from past experiences...may apply or may not? Assuming the temp sensor is located in the stock position..(threaded in on the top of thermostat housing)? sometimes this will give a false reading to the dash gauge if an air pocket is sensed inside the housing? Steam/air is hotter than water? hence the overheating/higher reading to the gauge? check this while engine is running with another type of temp gauge. you can use a drop in type (old style meat thermometer type) drop one in the hot radiator liquid while running? compare the 2 for correct numbers and reading. thats where to start....
also clutch fan operation WHEN HOT? if clutch fan is not working properly..this will cause hot engine temps...hope this helps...Ned

Restricter
by: Corvette-web-central

Is there a restrictor in place of the thermostat? You need to slow down the rate of coolant through the radiator. The heat does not have enough time to transfer to the radiator if it circulates to fast. These cars are notorious for overheating anyway. You may want to invest in a lower temp thermostat and upgrading worst case to an electric fan that can move more air at slower engine speeds! Good luck let us know if this answers your question or not. We are here if you need us!
