Okay, looking to extract a tad more performance out of our 4500 series Express. Anyone convert to electric cooling fan in place of the engine driven one? Or know what's needed to do this? I converted an earlier Tahoe but, that was easy as GM made the later models with electric fans...

Gary you might try using the "search" button. You can view all previous posts about it. Such as these:

Hardly seems worth it. You won't feel any difference.

 

Well that was easy! I must not have used the right words as I thought I searched the site prior to posting. Thanks for the links. As stated, it probably isn't worth the effort to change over to electric. Now I'm off on another chase to figure out what trans cooler I should upgrade to!
Thanks again,
Gary

 

Hahaha. In the process now

Park ave fans

 

Ray, that is pretty much what I had in mind...are the parts from another GM product?

Looks like a 97 and up buick park Avenue. The pull an pay in Lubbock runs a wheelbarrow aale. All you can stuff in for $100. I looked at fans all day. Theae are better than Cadillac and Corvette units. Getting the 2 ralays an thermostat is up to you. Boshe sells new ones reasonably. Im putt a 327 in my van so i did not grab the whole harness just need the plug ends a strong switch. I get battery disconnects at harbor freight for $6

 

looks awesome....please post up the whole job...a lot of us want to do the same swap...

 

Just had then on a 20 amp switch for each fan temporarily. Will be putting van back together in a couple weeks after engine is in. Took me all frigging day to re-engineer a rotor button that came with ignition. Getting old i guess plus you cant have confidence just to bolt on parts and i tend to use industrial hardware or at least marine parts whenever I can..every splice in harness is soldered

 

I felt bad that I didn't have any numbers on this project. Sometimes I just eyeball things if I doesnt affect suspension geometry or dependability. So here I go without knowing what I'm doing

Some of the things from jy. Dont go just for a fan. You will have a rainy day in garage if the virus dont get ya. Try to find a yard wit a pice list and sign up for notifications for the deals. Best are in Colorado springs and Albuquerque. I gotta find some more around Chattanooga

List all electric parts you want also. I brought back 2 amps and a sony stereo for garage mood music. Make sure you get pigtails for fans!!! New 50 anp Bosch relays is new parts. But wire on up should be grabbed while there. I haven't bought new fuses in 5 years

The fans coincidentally wer the same width as the fan shroud in gvan-32 inches i cut the top half of shroud to just lip over radiator half inch and removed bottom half. Frame mounts were 26 in wide so i just used cable toes til now grab and split hose for edges on radiator side (front)

Relays tuck in anywhere. Test your wiring 1st

I got a 2 position marine switch. Red side will run both fans- amber only one. . May change my mind after i get oill and trans coolers in front. Will check back iff yall dont get something. Todays project is steerin stabilizer and test stand for engine. Oh... part # if you need it P
