Aluminum Radiator

[VX KAT]

So even running Ron Davis' dual electric fan setup in a custom aluminum shroud, the truck is still overheating. Since it only happens when the a/c is on, I was contemplating replacing the a/c compressor. Doing so would cause me to replace the drier and expansion valve + vacuum out the refrigerant and put the a/c system on a vacuum.....i.e., a lot more work. I decide to give the new OEM fan (part # 8-97349-762-0) a try, along with a new OEM fan clutch. On the Isuzu parts website, they still have the old fan listed, not the new one, so it would appear that you can still order an older design. The new one is much more expensive ($241) than the old. I'll take some pics this weekend prior to installation. Figured that if this *still* doesn't work, I can sell the new bits on the forum and move back to the dual electric fans and replace the AC components.

The new fan has 9 blades, and are much more angular that I remember the stock one being. Anyone have any pics of the old fan to compare?

Thanks for that. The fan clutch only cost $82, which seems to have come down significantly, given your referenced post. That fan itself, however, was rather pricey.

Wow, that's great it came down...looks like I got the honor of paying TOP price

Yeah, I'm going to pick up 2 spares on Tuesday, provided this all works.
