Got a fresh rebuild, engine fires up runs great but will not come up to temp. I have a new oem thermostat, some cheapo aftermarket radiator, new oem oil cooler. Can start and run truck and with auto enginuity hooked up coolant temp start low and runs to around 90 degree and gets stuck. Oil temp climbs up great and everything else is within spec.
I looked at fan speed vs engine rpm and fan is around 250rpm with engine at 600-700 rpm ive ran it and drained the water a few times and it i can stick my hand in the water running out its about bath water temp.
What can I look at to get this thing up to temp? Air in the system maybe?
