cooling problem?

[rocker_topper]

Ok i dont honestly know if this is a problem or normal with these cars. just did a complete rebuild and while doing it i replaced ALL cooling components, sensors included. the car never overheats or runs the least bit warm while its running, but if i shut it down and come back about 5 minutes later or so (noticed after parking to pump gas) the temp gauge will be all the way to hot when i crank the car. coolant is full and temp returns to normal after cranking it. im a bit worried about this as i dont want to hurt anything. what do u guys think? Is it normal for the ambiant heat to heat the motor up that drastically when you shut it down? Should i be worried? Also one more quick note my cooling fan turns when the car is running but not when its shut down. i dont know if its supposed to run for a bit after shutdown or not though. anyone know?

Do a compression test, easy enough to rule that out, being the head gasket is ok.

What would compression have to do with the engine heating up after its been turned off?

Check it to rule out by. Then go from there with wiring and gauges.

Sounds like the sensor may be acting funny?
You could pick up a cheap infrared thermometer.

Check and see what the actual temp is.
