Chopstix,

Yeah, the Suburban also needs some tire spats. I am thinking of a conveyor belt design that has been discussed on here a few times, that way it can stand up to road/offroad abuse. I want to figure out a way to fit the OEM semi-smooth hubcaps to stock 8 lug alloys so save some weight over stock 8 lug steels.

I understand about overheating GMs because of air flow, I had a 1991 k2500… one engine and multiple transmission repairs later I figure out the AC condenser is clogged up and won’t let air through the radiator. (FYI go check and/or gently clean your condenser and radiator.)

If you are looking to DIY a electric fan conversion, search on here for the one I did on my Tacoma. It wasn’t cheap, but it is reliable. Also look at ducting the air into the radiator so it can’t just flow around. I did a partial grill block on a car I used to have, but also ducted the remaining opening direct to the radiator and my temperatures decreased, mainly because the massive airflow from the huge grill opening was going around the radiator not through.
