Phew it is stinking hot outside.
Yea, I will admit my El Camino had to sit and idle for a few minutes and the temp probe is up on the front bumper close to the fan for the radiator. Sitting at idle the air will crank the temp up pretty fast. Once I get moving it drops to a more realistic number.
The AC was blowing 40 degree air and the engine temp was at 215. Not bad for a 31 year old G body GM car. Long ago when it was a 41,000 mile car, still 100% stock we drove over to a relatives house. It was a hot day and the hot engine light would flicker on and off. It had no gauges back then except a fuel gauge. And it still had the stock 2 core radiator, and a wimpy water pump. With the three core radiator and the extreme duty water pump it does just much better.
