On some of the V8 small blocks, the aluminum intake manifold and cast iron block used to have the expansion and contraction happen at such different rates that the intake gaskets went bad and the antifreeze would start leaking out. Not sure if the V6 had the same issues. They make replacement gaskets that mitigate that problem. Another idea would be to find out if the head gaskets were ever changed. Might be possible that the wrong gaskets were put in and blocking some coolant passageways.

We replaced the radiator and put in a 3-fin in place of the original 2-fin, and that really cooled it off. Otherwise, replace the radiator instead of just a flush. Also, check the compression. You may be getting blow-by on one or more cylinders. That can really heat up the oil (and then the engine). bp <part15sbs{at}gmail{dot}com> On 9/17/2017 5:06 PM, Jaime Solorza wrote: My wife bought a 2001 4x4 Chevy S10 Vortec 4.3 from sons wife. We knew it heated up a little...I replaced water pump, fan clutch, thermostat, had system flushed including heater core along with radiator. It doesn't heat up us as much...you can run it on freeway with temp at 210 degrees...once you exit and stop, it gets hot for a bit then cools off again. No detectable leaks, no water in oil...wonder if sensor if faulty...any ideas or tips...we want 4x4 for winter hiking season. Thanks
