I also have a problem. I have a 350 crate engine, new water pump, new radiator, direct drive fan, etc. It is heating up when idling in 100 degree weather with A/C running. Runs cool at 70 mph regardless of weather.

At this point, my only guess is that I have an A/C radiator support and a non A/C shroud. The shroud has about 1/2" gap all the way around the sides and bottom of the radiator. The top is close to sealed. According to the LMC website there are different shrouds and different mounting methods depending on A/C or not.

Does anyone have pics of both fan shrouds installed and uninstalled? Thanks in advance.
