ARGH.......
Did a radiator pressure test, have an 18 lb cap on presently.
Put 18-19 lbs in it, lost a touch at first and than stable at about 17 lbs for 3-5 minutes.
Replaced the temp sensor following that, thinking sure enough all along its just that simple.
Temp gauge still climbed while under load.
Temp gun readings, which all should be about normal. Slim chance I got a bad sensor or between it and the gauge???
Readings
Top Hose - 180-185 (same as the top of the radiator)
Bottom Hose - 120-125 (same as bottom of the radiator)
Temp at base of sensor - 170-180 -On the brass part of the sensor 200
Thermostat housing - 215-220
Water pump - 200-225 depending on what part of the housing
Throttle body (both sides) 210-215
Valve Covers - 180-185
Everything points to a normal running engine, but I honestly don't trust it.
I'll probably throw another sensor at it, but ???
