[AFMUG] OT: S10 Chevy heating issue

[Jaime Solorza]

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
