Need help! car over heating!

I have a 73 240, and what are the symptoms of a z car overheating? My temp gauge goes up to H really quick sometimes and other times it doesnt. Im thinking maybe the thermostat is not opening? When I turn the heater on to help cool down the car, it doesnt do anything. Have any of you guys had this problem? Where is the thermostat located btw?

It sound like the thermostat. It is located on the front of the head where the main coolant line comes in. one way you can test is to take out the thermostat then replace the housing and see if that helps. If not get your radiator flushed.

get a hold of an temp gun and point it on top of radiator by the hose and measure the temp there when your car is reading high. normal should readings should be around 180 deg. if it reads around 180, your temp gauge is not good.

I know this sounds simple, but is the radiator low on coolant? Low fluid can cause spikes in the temperature.

Its more likely you need to replace the $5.00 thermostat.
