So I got it all together and tested it. It was 92 degrees in my garage when I started it up.

I figure if I went this far, I was really going to test it. I've been a S-O-B to this car for 19 years, why should I stop now ....


I let it idle for 25 minutes not moving it an inch in the garage!


The front of the car was 1 1/2 ft from my washer and dryer. So no wind to help it. Even though the garage door was open, after 25 minutes my eyes would tear up if I stayed in there too long. After 25 minutes, the car raised the temp in the whole garage to 98 degrees.

RESULTS


1) After 10 minutes idling, temp measured on heat gun was 160 deg. at the temp sender.




2) After 25 minutes idling, temp measured on heat gun was only 203 deg. at the temp sender. Turned it off and no boilover whatsoever. I didn't think that was bad given the extreme abuse. It was a fricken nauseous sauna in there.


I think it did really well for such an extreme test ??

Here's a picture showing the suction of a paper towel on my grille at idle and the ambient temperature there.
