Instead of paying big $$$ at the dealer for the green o-rings, is there any reason why I can't remove my hoses and just go to the auto part store and get some? The R134a A/C o-rings look like the same color and material.

Go to a knowledgeable auto parts store to get them. (O'Reilly or NAPA are usually good for that kind of stuff. AutoZone is not.)

There's nothing fancy or special about them. You'll need four of them to replace both sides of the oil cooler line if I remember correctly.

Just make sure to bring one of them with you to compare it side-by-side. All four of them are the same size.

AstroVic is correct, except that there are 8 o-rings; two ate each end of each of the two lines.

That's right, there are eight of them. I was forgetting about the return lines.

What a disaster that turned out to be!!!!!!! I took it apart, removed the o-rings and then was on a 3 hour expedition to not find anyone who had them (Sunday). Went to put them back on and ripped 2 of them, so off to Home Depot I go. Luckily they had some almost identical but they were black. Will the black ones hold up ok?

Uh.... I hope you didn't get the nitrile/buna-N o-rings used for faucets at Home Depot...

Might I recommend silicone or PTFE? If anyone else can source out a vendor please post it.

otherwise www.mcmaster.com is my contribution. If you can provide me with the OEM o-ring sizes I can find the corresponding o-ring on mcmaster (or you can do it, search for O-ring).

PTFE and Silicone have the widest temperature ranges.

Of course, you could also get OEM replacements if Ford sells them???

If your new o-rings smell like nitrile rubber, do NOT use them. They are the cheapest and weakest o-rings you can get.

What does nitrile smell like? How else can I tell? They were with all the other facet orings. I still have the original ones, but I have no idea where I can get them, I heard the dealer wants an arm & a leg for them.

Nitrile smells like rubber but not cheap chinese rubber. It has a distinct odor to it. If you've worked with carburetors, the gaskets used for the carb/intake manifold seal are nitrile (becuase of contact with fuel) and it smells like, well, nitrile.

I'm not sure what Ford uses, but I suspect it must handle at least -30F to +200F and be in contact with hydrocarbon/oil. Buna-N/Nitrile meets this but I wouldn't rely on it. If Ford does use Buna-N/nitrile, then it explains why it leaks after a certain time.

PTFE/Teflon and Silicone can handle -100F to +400F and have greater resistance to a variety of compounds.

Well, I ran across this article as was curious if these o-rings will fit the newer hoses 98~02? I guess mine are nitrile. I better just get the ones from ford if they will fit.

O rings? Is that why the oil cooler lines under my car leak? How big a deal is it to get the two hoses off?

hot damn, it's a good thing I don't have the CVPI oil cooler. That's just a leak waiting to happen

The E-250 has a oil cooler but the oil passages are cast into an assembly. The hoses only carry coolant.

There are plenty of reports of leaks with the CVPI oil coolers.

Well, I will have to do a search and get mine fixed. Sort of glad it was not just me.

Thanks
