Update: I talked to Performance Radiator again and we’ve elected to take my old rad and remove and clean the passenger side take were the oil lines connect and put it onto the new HE rad. Then I know my oil lines will fit and I’ll get the benefit of a mostly new rad.

Thank you on the clutch mod. Turns out the rad shop said GM changed their thread pitches that year.....gave some adapters but he gave 18 pitch male side and 18 on the female.....getting closer. I’ll take the new rad and oil lines into their shop tomorrow and get it resolved once and for all. The...

Ken, I decided to use a micrometer and a drillpress and drill the new holes offset. Used a 1/2 socket which the OD was just a papers width under the hole for the centering stud on the pump pulley. Made a template and went at it. Came out perfect and couldn’t have fit better. Pic below. Now for...

Ken, thank you for the added info that really helped my piece of mind. i found one on fleeBay on close out for $44.99. I’m going to take a chance on that one. i really appreciate the assistance.:naner:

Ken, The information in the specs pdf for the Hayden 2828 don’t list the bolt circle diameter. Happen to know....just don’t want to purchase another item I can’t use. Thanks a bunch

Ken, Thanks for the part number! Below is what it said it fit in the listing so I thought I was good to go, but I guess not. After seeing the list I figured the odds were in my favor. :cry:

Update: so I’ve Learned a lot about radiators. Turns out they have quit doing 4 row (core) radiators since they came out with a high efficiency 3 row design that uses smaller fines and tubing. I’m told these are the new wave rads. Anything that was 3 rows gets 2 now, yada yada yada..... So I was...

Will do, thanks

Update: Paradox kit installed. 7 bladed fan from a Suburban 6.2L on the way. Ordered 4 row rad from Performance Radiator. I’ll install them both when they arrive. Also, cucvrus the radiator looked a bit worse for wear once I removed the top cover and shroud for a better look at it. Thanks all...

Yeah, I was going to reach out to you and see if we could meet up, but my second born man-child was graduating high school and it was a hectic time. I’d love to get a gathering of Colorado CUCV’s for a off road weekend.

It sure does. I won’t post a link to it but it’s the only 6.2L fan clutch on fleaBay currently. Hmmm I wonder if cucvrus has any laying around. I’d rather give my money to someone “known” here.

Doh! Thanks Tinstar

Update: So I’m back in Grand Junction. It took the same 5hrs to get back as it did to get to Denver, but I didn’t stop nor did the idiot light for temp come on. Instead of 32mph in 3rd I did 25-27 in second gear on the steep grades and I didn’t keep it floored everywhere else. She ran great! No...

Ok. I’ll check it out, but at 29k with good maintenance records I’m not real sure the cooling system is bad. Thats why I bought her, it was dang near like buying a new truck. I do see a benefit of having Performance radiator build a bigger aluminum unit maybe. thanks

Ok. Thank you all for your input. I’ think i’ll Start with a 180 t-stat and the 7 blade fan. Does anyone have a part number for that bad boy? and i’ll Slow down a bit and enjoy the scenery....lol but at 32mph up the hills here in Colorado all I was watching was my idiot light.....:neutral:

So I did some Googling on the Interwebs and I’m not seeing any “rear cylinder bypass kit“ Or am I being a bit slow? Thanks all

Same here. 29k clean as whistle. So....after all this how do guys even move these CUCV’s with lifts and 37” hummer wheels? I would think you have to have 12v Cummins swap and a 4L80E

Thanks I’ll look into this was well.

Gripy - Yes out of the overflow tank. Ugh. 25...well it’s not much slow than 32mph. 2insane - upgraded water pump is a thought. Top down view of the rad is clean as well as the coolant. Use the electric fans as pushers?

Hey All, I took the old 1010 to Denver Sunday and she did great, with one exception. She didn’t use a drop of oil, nor ATF, but she did puke coolant a few times. I have 33’s on her and even though her top speed is now 70mph, I kept her at 55 the whole drip. But climbing Vail Pass and The...
