| Ive sued a heat gun on the radiator, varies about 20° top to bottom, with bottom the coolest but this was with it running in the shop for ~ 15 minutes. I also took the rad cap off at that time & there was no bubbles.. Coolant was changed last year, had less than 100 hrs on it.
Hoping it was an air bubble , had that happen sectoral years ago on a 706 tractor, but the way my luck has been going I fear a blown head gasket. | |
