Just bought a 96 suburban with a 5.7 auto and 87k. Clean on the inside and carfax looked ok, no milage rollbacks or accidents. Paint is not to great but I wanted a mechanically sound one not pretty. Spent some money right after buying it to just be safe. Coolant flush, tranny flush, rear end fluid changed and a good looking over. They found a leaking heater control valve and that was no big deal. Drove about a 100 miles and noticed a coolant leak. Took it back to the shop and the dreaded lower intake gasket is leaking. Well now I am getting worried. This was a 700 dollar fix or there abouts so I say go ahead. A few days later I notice more coolant under it. Maybe a hose is loose or what else is there. Well how about a head gasket leak now. About a grand and that is a deal I guess after throwing a fit at 1300 plus parts. I bet someone had overheating issues at some point and put a leak fixer in and sold it to me and I had it flushed and now it is puking coolant on a regular basis.
