I just had a 6' plow mounted on my '99 6x6 and experienced radiator overflow (over heating) after the first hour of use. I am completely new to this site. Anyone have any suggestions?

The plow is going to block "some" air flow, but most people don't have that issue, so I'd make sure that the radiator is perfectly clean. I've seen MANY overheating issues caused by a partially clogged radiator and that would definitely be the first thing I'd check.

Your location isn't listed, but I assume the weather was cold if you're running the plow?
