I am new to the site, I have a "96 S-10 4.3x 4x4. I had a radiator leak and it overheated, against my better judgement I let it cool a bit and continued to drive home, Approx 7 miles, I have replaced the radiator and thermostat but it is still overheating and I have no heat. I see no leaking while idling but as I test drive it overheats to the "danger zone" fairly quickly and I am losing coolant. I suspect head gasket, but am not to savvy at diagnosis, I would like any suggestions or opinions before I start taking it apart. Thank You

 

Do a couple searches. One for coolant flush, the other for lower intake manifold gaskets. Both should come up with a lot of hits.
