I'm ordering one from Summit. Looks like I am going with a Hayden 459. 7.5X8.75X.75 core, 12.5 inch overal width. It is a tube-and-fin type, and not plate, but it has 1/2 inch lines clear through. I can't find a plate cooler with half inch or bigger lines, without having to screw a fitting into the inlet/outlets. I am going to see what NAPA has in the way of coolant valves and plumb the current 3/8-tube cooler I am now running in parallel with the big one.

I have about an inch between the grill and current cooler, so I figure the 3/4 thick cooler should be a good fit with the condenser behind it.

 

Advanced Auto has some good coolers I just looked at with 3/4" lines. Check it out.

 

Advanced will only show me the stupid 3/8 line coolers, like NAPA told me I need. I don't know where the nearest one is.

Autozone has some bigger ones that they say have 5/8 male pipe thread fittings, but the picture shows female compression type fittings.

I think Summit's got this one. At least they seem to know about the cooler line size.

 

Maybe Summit won't get the sale. It's got some extra parts, for use as an engine oil cooler. How hard can it be to make and sell an oil cooler without a bunch of extra crap, without swaging the lines down to 3/8 inch first? Geez.

 

I just thought of something. A 1/2 inch wrench will barely fit over the steel trans lines on my truck. So that'd be 1/2 OD, probably 3/8 ID. The rubber lines from/to the trans are squished down pretty good onto the nipples that connect them to the cooler lines. I bet if I look closer, I'll find the hoses on both sides of the nipples squished down pretty good. I bet that drunkard that dad had put the cooler in for me last spring dug around and found a piece of 1/4 inch pipe and cut a couple pieces off for nipples, and if I go get a couple 3/8 hose barb to 3/8 hose barb nipples, I'll lose my restriction in the system, and the leak where the steel line was cut and replaced with a piece of rubber, down where it crosses from the passenger to driver side, won't leak so much.

Feel free to call me a retard, if you think it's warranted.

 

can you just by a cooler that has the half in lines in it and run all new lines to a new cooler if i can im just putting a new cooler and lines since mine is rotted out can i buy an cooler? or does it have to be for the cummins or some thing of that size
?
