My 2002 Suburban is due for a coolant change I believe. It was last done at the dealer at 60k miles about 3 1/2 years ago.
Whether this means anything or not it seems that the coolant is low (about halfway down the expansion tank when hot). The oil doesn't seem contaminated at all.
What is a good coolant to replace this with? I realize Dexcool isn't generally liked by a lot of people but I don't think there are issues with the 5.3L, are there?
What is a good method of flushing it out? My Haynes manual says to drain it from the valve at the bottom of the radiator and to flush it out with a garden hose.
