98 Chevy K1500 HELP
I currently have a 98 Chevy k1500... It's not going above 150°F and I get horrible fuel mileage from that, and no heat. It has a brand new motor, radiator, water pump, heater core, all cooling hoses, temp gauge, temp sensors, radiator cap, and I've tried 6 different thermostats many different mixes of coolant, the fan clutch is good. I've tried blocking off the front grill to keep the air out and that didn't help, so I removed the fan and the temp still stayed in the 150°f range. I manually tested the temp of the motor with 4 different temperature guns, and probes, and I get the same reading with all of them that matches the gauge.

I am as stumped about this as you are. Usually, the engine overheats. That heat has to be going somewhere, but I don't have a clue as to where it's going. You are correct about the 150 F temp being way too low.

curious but have you ran the temp gun on the exhaust manifolds to see what their temps are? your cel isnt on? im with oil can im stumped also, i mean even with diesels if you block the rad 75% i will get a little warmer and 100% should run really warm. the only thing i can think of is if maybe not all cylinders are firing or too much fuel causing the engine to run rich but ive never see it make an engine run that cold
