leaking oil cooler question

Hello G&Gs,

Seems the head end (toward front of engine) on my oil cooler is leaking. rebuilt it propably a couple years ago with all new O-rings. Just waiting for it to warm up a little and will do it again. Antifreeze is clean, it is just leaking, specially now that it's winter temps here. When I last had it appart IIRC at the time was thinking of putting two o-rings on (the fatter ones) on the head assembly as this is where it is and was leaking. Right where the actual cooler slides into the front assembly. In other words the front o-rings would be a single thin one (seperates oil/antifreeze) and TWO fat one (if they fit) for a total of three on the front end of the cooler assembly.....What do you think? Any other suggestions would be great......

I would leans towards a slightly larger profile O-ring before trying two in a groove designed for one.

Re: leaking oil cooler question

Good suggestions guys thanx,

The original cooler leaked at the same place and so I replaced the entire unit which I rebuilt of a SD engine. Put in new o-rings and gaskets. I guess the good news thus far it's not leaking internally best as I can tell. Looks to be leaking between the head and cooler itself at the front. I have all new stock o-rings and gaskets to rebuild just wondering Tom, any suggestions as to material type for larger (thicker o-ring)? I have a general o-ring kit in my garage and had thoughts of using it as they are HUGE less expensive than the IH and Ford ones, Gold comes to mind......

This is really not a big deal just a pain (whaaa) in that it's a bit messy.....

Re: leaking oil cooler question

Remember they (O rings) might be metric sized.
