Thinking about redoing my cooling system; the current one is o.k. for driving around on freeway or in town, but didn't quite cut it last year in Moab at BB'02. The motor is an '85 350 with vortec heads and headers; it runs a bit hotter, probably due to the increased compression. Cooling system is a Stewart water pump, 195 degree thermostat, 3-row radiator that has seen better days ('reconditioned" when I got the truck in '97), and two 14" PermaCool electric fans (that supposedly draw 2900 cfm each) with minimal shrouding. Tranny (700R4; 4.10's w/ 33's) is plumbed separately to a big B&M cooler; no engine oil cooler on the truck. Truck has A/C; condenser seems in reasonable shape and not plugged up regarding airflow. I've been looking at new radiators, essentially 28"x19" honeycomb area, either 3-row or 4-row. But from measuring a bit. it seems that I might be able to put a wider radiator in, if I move the evaporative canister a bit. When looking for other options, such as aluminum, I found that radiators for '94 and such come in a HD 2-row aluminum version. The tanks left and right, however, are plastic. Does anyone have experience with those? How do they hold up? Opinions welcome on which radiator to go with, and don't worry about overcooling the truck in the winter - no more road salt for this truck. Thanks for the input, michael Oh, yeah, I could go back to a belt-driven fan, but I really like the reduced noise - I'm just getting old, I suppose.
