Still fixing all the little problems after doing my 6.0/4L80 Swap into my 87 Suburban. Along with the motor installed an Enytropy radiator/fan kit.
Fans come on low speed then high speed like they are supposed to.
When I'm driving and have airflow through the radiator, everything is fine, once I come up to a light or stop, temp goes up about 20-30 degrees, even if the fan is on high speed, then goes back down when I start moving. When I installed the motor I replaced the water pump and thermostat with new AC Declo parts.
Any ideas?
