Ok guys ive been having a huge issue with my truck and have checked every forum out there. I have a 94 chevy k1500 z71 with a 6 in suspension lift and 3in body on 35's. its got the 5.7L 350. so one day my heat just seemed to stop. i had heat on the way to the store and when i came back out and started my truck up, the heat was gone. i have replaced my thermostat and am confident its a 195 degree but it shows on my dash that my truck runs around 150degrees, i flushed the heater core with water and air, then i knew i had a garbage radiator (cracked, lots of bars leak in it) so i went ahead and replaced the radiator hoping then id get my heat back. Still no luck. i have also noticed the radiator hose from the radiator to the motor is hot but the hose from the block and back to the radiator is not nearly as hot. ive burped the system and still nothing. any ideas??? really cant handle these illinois winters without heat!!
