Aluminum Radiator

[VX KAT]

Sue thanks for sending this to me, as I am too lazy to search here lol, anyone know temp values before and after this? Anyone else have this radiator? I would love to know a temp number that Sue ran in AZ heat with that new radiator.

See posts #28 and #37 above, I gave some scangauge temps.

OMG amazeballs! Yes I got the torqflo, very loud, but I don't care! We pulled radiator off yesterday and had new ones to swap, but mine was perfect, no buildup on bottom, BOTH VXs ran hot after they got to over 80k miles, which makes sense that it's been fan clutch, both my VXs would get up to 220 and run rough in traffic, now I can't get it over 172, huge difference! We tried electric fan conversion on mine years ago and it came right back off, ran even hotter! I don't care if it sounds like a semi lol, I just can't believe it was such an easy fix that seemed too easy all these years! Thanks guys!

Yeah, and for what it's worth the torque flow has quieted down a little for me after a few months, but the ScanGauge is still reading 173 consistently running AC in the heat. Occasionally it will get to 182 but since installing it has not seen 190.

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?

P.S. The invoice also says something a bit disconcerting: "Dealers are free to sell these products at whatever price or margin of profit they choose." Nice :-\

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.

New radiator, fan, and fan clutch did the trick for me.

Where did you get the new Isuzu style fan and fan clutch at a good price?

Me? Scarff Isuzu....only place I know where to get OEM parts, although I wouldn't call $241 for a fan a "good price".

I didn't have any problems with my RD radiator in Moab this year. Made a custom aluminum shroud to hold my 2 10" electric fans (not sure what brand, got them used from a friend) and everything has been great. Holds temp at just below half gauge driving around without the fans, and stayed the same on all the trails with the fans on. I didn't run the A/C at all in Moab thanks to my blower motor being dead, but I am confident it will be fine this summer.

Well, so far, so good. I've been running the a/c full blast every day, no matter what, and it hasn't even moved past 1/2 way. I even spent time on Tuesday purposely sitting in traffic, as that would always cause it to overheat in the past. Waiting for a 100+ degree day in full sunlight before I'll call this one closed, though.

With ya here, drove yesterday and prior to change of fan clutch, about 2 wks ago, would get up to 220+ with AC before I would shut off AC in traffic, yesterday max it got up to was like 188 in traffic and it was what 86 yesterday? AND I drove it hard on the toll at about 85 mph for about 15 min prior to sitting in traffic. I am such a happy camper!

I'm confused with the different references here... having overheating issues myself when AC is on. Noticed condenser fan wasn't working off and on but not sure where to get the best deal or quiet fan.

Is clutch fan the fan for the radiator or is it the one in front for the AC condenser?


Does anyone know the actual diameter size of the condenser fan ?

Is there a good universal or common aftermarket replacement for it?

Going to try replacing engine temp sensor for first fix as I hear it is a easy and cheaper fix... any suggestions on this and/or prices and deals?

thanks everyone!!
