I'm a little uncomfortable with the high temperatures I register when taking the temperature with a IR thermometer on my 351 Cleveland. After 10 minutes drive at 50 - 60 miles/h I stop. Thermostat housing is 210 F, lower hose fitting 160 F, heater hoses around 130 - 140 F. I don't loose any coolant. It seems that the water pump is functioning, otherwise I would have much higher readings and more uneven readings, IMHO. What is your comment to this, perhaps it's normal? Have to ad that the engine is slightly souped up, and have headers. I looked at the FSM but there is nowhere they talk about purging air from the block, as I thought there might be air pockets.
