Ok so I purchased an aluminum radiator for a 2000 s10 my trans cooler lines thread right in no problem. My oil cooler lines will not. They are clearly the same style connection on the new radiator as the trans but larger. The listing had trans cooler lines listed but not oil cooler threads listed. So my question is. What is next size up, in the same style and does a quick connect option exist. Any help would be so much appreciated im putting this in my dads truck that I can’t afford and now because I don’t feel comfortable with a plastic radiator after blowing an engine cause one broke I’m looking at having to spend money on something else or trying to delete the flipping oil cooler which I have brand new lines for.

what I need
figure out what size threads they are and an adaptor to factory or be able to plug factory hoses directly into the fitting.

please any help I would be so grateful. I don’t mind helping my dad but this is starting to really hurt me financially.
thank you all.

 

You might look at what Dorman has.

I will check them out. Using my caliper and google, I did figure out that the existing thread size on new radiator is 3/4x16 unf. So I just need to find a quick connect fitting now! Lol

 

Ok after lots of searching and trying to figure options out I realized there is none except to order another radiator and hope I get my money back. There’s no room for adaptors with factory air box.

 

When I put in an all aluminum radiator I had to do some mods to get it to fit.

One of the things I did was take a heat gun to the airbox to deform part of it to clear one of the cooling lines.

I should have a post about it in my build thread.

 

yes I read your build thread several months ago. I’ll have to revisit it.

so 2nd radiator came and threads are all correct. It even came with fittings. However the oil cooler fittings are not drilled for the prong it’s just a dead stop. My idea is grind off the ps style and use thread sealant and flat rubber oring inside and a print on the outside lip. I was thinking maybe I could find something oem from maybe a bigger vehicle.possibly a Kodiak

 

That is great you got a radiator that looks likely to work for you. Be sure to post pictures and describe what you did to make it work.

 

im really nervous about the modification and wish I had a better option.

 

Before you do the mod, you can share some pics here to get some feedback before you commit to it.

If you looked at my thread on my aluminum radiator installation, you saw that I had to get a local shop to cut a hole and then install an oil cooler! That mod has held up perfectly!

 

Ok pics of before.



1st. Cut off end of fitting and grind down as needed. I went farther then I wanted as I wanted to smash the oring tight enough for a seal but not crush it and have tight threads as well.


2nd.
I added dielectric grease using a small pic to get just enough on the base of fitting for oring to spin freely. But not get on the threads and mix with thread sealant as it does cure hard. Same product used for head bolts.



3rd.
install and tighten up. I will be using radiator manufacture fittings for a final cut to try to get tight threads actually, along with a tight seal by grinding down a little less. This is what my first fitting attempt looked like. FYI: the fitting is very very soft doesn’t take much.




4th. I wanted to address the heavy gauge battery to fuse box wire on this forum, after reading thru Christina’s build and one of the others that ordered the same radiator said he had to move his but didn’t go into details. It sounded like he actually did a bit more work by simply saying he moved it, So I wanted to give a simple fix for others in the future.

I used an old 1/2 extension and a 4lb sledge to indent the factory indention deeper on the side that meets the front lower plastic of the 3 piece fan shroud. Took a half dozen plus hits. Worked nicely though. You’ll also notice hvac foam tape used to secure wire on top of the core support without drilling any holes causing a rust issue. Product holds up to oil pretty well in hvac lines and sticking to the refrigerant lines so I felt it was a good option. Not worried if it fails down the road really as radiator will be in place.





Last I’m waiting for a final response from distributor trying to determine if I’m dealing with a defect or design flaw!
