So the whole 87 Chevy Dually project just took a turn. I'm upgrading to a serpentine belt and part of the kit has a mount for a R4. Well I have never been a fan of those, and there is a kit for mounting a 508 into the R4 brackets. Will the 508 be adequate for cooling the crew cab in AZ heat? Will the 508 work with the cycling OT setup?

Thanks

Might look at using the 510. Many have the same mounting tabs as the 508 but larger capacity. 508 should still do the trick.

Thanks Tim. Do you have such a 510? I'm done with parts store failures. It will need to have a serpentine style pulley. If this works, I'll be doing this same swap on my diesel Wagoneer when it gets back on the road.

I have the after market version. Just make sure you have a little more room off the back of the compressor. 510 is a little longer.

None with the serp pulley?
