99 Blazer, 4.3, 4wd
I just finished replacing the head gaskets/passenger head last week and found a leak in the radiator today so had to replace that as well. I am wondering if it is normal with a new rad and having a "clean" system that the lower hose stays cool? All the other hoses are hot, am getting heat, running normal temps and no other cooling issues noticed. Also at startup I am getting a squeal seemingly from the water pump (replaced this January) that goes away most of the time after it warms up. Any suggestions?
