View Full Version : fan shroud optional?

07-25-2007, 12:33 PM
83 chevy pickup with 350 motor on propane, stock water pump, 160* t-stat, large 4-core rad, will see mild towing, daily driven truck. The fan shroud i have is mangled, thinking about just using the top half around the mechanical fan or even taking it out al together. Will the truck overheart? I've got ample gauges.

desire to overheat is optional, so I suppose a fan shroud is optional too...:dontknow:

fan shroud is a must for low speed high load driving

Go with the shroud, you'll thank yourself later. And make sure the clutch fan (if it's got one) is working when hot, should be pulling lots of air (noisy).

A fan shroud made a huge diffrence in my truck. I was overheating every 40 mins, with the new shroud havent had an issue yet. Truck cools down at idle now too. Heres the post from when I built mine, you can probibly make one yourself. http://www.funinbc.com/forum/showthread.php?t=81216

i have 2 plastic ones, but its a pain in the ass to get them to fit with the 3'' body lift.The one i got looked like it would fit, but now its got a 2.5'' gap between the rad nd the edge of the shroud. Guess im heading to a wreckers to find one.

Its a mechinacal fan. My old one worked, guess shes going back in.

I'm not good with sheet metal.

Definately run the shroud. You'll be kicking yourself otherwise...

back to the zap straps and old shroud it is. How did you guys running body lifts mount yours?

on my old 4runner the body lift kit came with brackets to relacate it. Deppending on how your bolts on, just some siple flat bar with holes drilled 3" apart (or however big your body lift is..) for each mounting spot. Bolt the flatbar in, then use some smale bolt to attatch the shroud to the flatbar.

Thats how it came with my body lift kit from Performance Accessories.

i used some of that flexable metal strip thats got holes in it every 1'', that is what i used for the bottom, now its the top thats not lining up. Stupid body lifts.
