Has anyone ever sourced the o-rings for oil cooler lines (at the radiator) from a local auto parts store?

 

I have tried, cant get them local, had to order them.
I ordered extra since they are so small ordering 8 vs 4 makes no change in shipping.

 

Thanks Spike.

Are they the same for oil and transmission?

 

Yes they are the same.
AtlanticBritish sells them, like $2 each.
I tried to get them local, no go.
The import shop would probably have them, they are nothing special, just need to find the correct size.

 

Go to a hydraulic shop. $2 for an o-ring is highway robbery.

 

I used AC o-rings from Napa for like 35 cents. No leaks.

 

I can't remember off the top of my head what diameter they are (6mm maybe), but a caliper will tell you real quick. Then, hit up one of the chain automotive stores for their assortment or individual ones if they sell them that way.
