I've been deailing with this odd problem for a couple of months now and I need some kind of advice on what to do. I'de been diagnosed with a blown head gasket as the cause of my problem, so I made the following repairs. Head gasket replaced with OEM gasket kit,.head was machined and cleaned like new buy a local shop. New Radiator, Hoses, Belts, Fan Clutch, WaterPump, Thermostat, Temp. Sending Unit, EFI Temp Sensor all this stuff was pretty much a "while I'm at it Might as well" type repairs my truck has +240K and i figured while I had it apart, why not. But still my Tempurature Guage climbs and climgs telling me I'm overheating but my radiator Isn't hot, hoses aren't hot no perkulating in the resivoir or any typical overheating symptoms. Any suggestions?
