Okay, the jeep was at the shop all day today. The water pump, tstat, and rad cap were replaced 6 months ago. The radiator was replaced in 09.
According to the radiator shop (family friends that go back to the 1930's, so i trust them) they cant figure out why its overheating. So were going to replace the tstat that the cheap shop in san diego put on and see it if helps.
Would i be able to tell if the lower hose is deteriorated from the look of it? IIRC it was replaced in 09 as well and looks normal.
The fan spins with very slight resistance when cold. for maybe a quarter turn it has a bit more resistance than the rest of each complete spin. when i rev it, it starts to blow real strong and seems normal.
And to think I was about to take this on a week long trip all over California in 5 days.
