Re: electric fan vs shroud

I had a hard time keeping my truck cool before I had a shroud too. I went elect. and that didn't work. I tow approx. 8k of stuff to the lake during the summer mos. when it can get real warm. It took me a long time to take everyone's advice but I got a stock repro shroud, a 6 blade oem fan and clutch. Running a stock 4 core brass radiator with a 190 deg. t-stat. (I like the engine to run a little warmer). I've run this truck up around Sacramento area, sitting in traffic, 105+ deg. days and have NEVER had an issue. No pinging, dieseling ect. Before the shroud however, I couldn't even run to the corner store two blocks away without boiling over. I'm not saying it's for everyone, but the factory setup worked for me. When it starts getting warm, you really hear the fan kicking in. It can be a little annoying but way less annoying than wondering if you're gonna overheat on a hot day.
