Hey guys I have a 99 Suburban, and slowly its starting to have more problems. I just wanted to get on a site that is geared twords Suburbans. I had a 1990 in high school that lasted to 240000 miles. Its still running strong. However I have a 1999 Suburban and its currently overheating constantly. Hopefully I can get some good advice, as well as give some good advice too.
Hey guys!!!

Welcome aboard,(Well they are boats)
Try a complete engine flush, someone may have used porta seal or some other type of radiator sealer and clogged something up.

Actually shouldn't be too hard. Only suggestion I have is that you lay a small coating of RTV sealant (high heat) around the coolant ports of the heads, and intake manifold. Doesn't matter if the gasket has a sealer embossed on it. This will help prevent future leaks. Only the coolant ports, leave the intake ports alone.
