If you zoom in on my picture you can see the Gates part number on my hose, it’s a 1.75”. I think it’s from a G van IIRC
I’ll be dipped, there it is. After all the digging, the time spent on Rock Auto, parsing through websites, there it is. I’m going to save that on my truck file and I’ll replace that cobbled together hose I have on mine. Appreciate it!
I bought and returned at least a dozen hoses at O’reiley before my dad found that one in the Gates catalog, I think he looked through the catalog for days before finding that and a few other options
There’s a Shell station across the street from “Oh-Oh-Oh, O’reily’s!” that we have bought several cases of beer at while on parts runs
As much as a I love the quality of Cold Case (it is absolutely beautiful) the salesmen that answer the phone know nothing of our struggles. They probably made these radiators for both vans and our trucks, but when I asked them what truck used a 1.75 lower, “um some big blocks did”.
There is no such thing as a 4-core once you go to aluminum. The equivalent thickness 4-core brass radiator is a dual core aluminum. The tubes are squished flat and have internal turbulators in the tube to improve efficiency because the aluminum is inherently less efficient at dissipating heat than brass is.
Clutch fans are quieter, don’t rob as much HP, but when you get one, watch your temperature gauge! I got a bad one from NAPA, and it was non functioning and almost immediately overheated my truck the first time I drove it in traffic. Save your receipt.
I just looked at your fan Pic. Get that off of there,and replace it with a factory fan,and fan clutch. Or get your electric fans but those flex fans with no clutch,have a reputation for coming apart and hurting people and damaging hoods. IDK how much real risk there is,I won't run a setup like that. I do know that they aren't as efficient as your factory fan and clutch were.
I was looking for incidences of flex fans coming apart there were a bunch,way more than I would have believed or expected. But I stumbled across this little nugget of joy that I told someone on here I try to find. The actual horse power difference between an electric fan and a clutch fan aren't worth the money or effort in my opinion. But the top 2 for horsepower are 487 stock and 494 electric,and IMHO an average clutch fan and shroud will cool the truck just fine,not worth the effort and money for 7 hp which still isnt accurate because an engine dyno isn't going to have the loss from the alternator working,let alone working harder for the electric fans.
