Well... Temp gun to the rescue?
across the head at temp is relative to the REM & guages 220, and temp gun shows 210 on the head front to back
water inlet hose... 95...
water outlet hose 95...
water pump 110
thermostat housing was at 150
Looks like a failed water pump...?
aside from that... typical electrical gremlins... multimeter doesn't read.. soo time to chase grounds and make sure their good. even across battery posts + to - no volts displayed even though REM & dash shows good running voltage
as a dummy test, I tried the spare fan against the leads and on another vehicles battery posts for a comparison, Results were satisfactory.
