Hi,

just a quickie, my old girl is marking her territory again after a helpful garage did something to the brand new oil cooler I’d fitted (hose union but now won’t tighten -suspect thread is b*ggerrd).

I have another brand new cooler to fit but getting the time to do it is challenging. So I wondered whether PTFE tape might help seal the dodgy thread as a quick fix ? Or is there the potential for it to damage the hose union ?

Thanks again

Bob

I would attend to it ( replace the cooler and or the hose) as soon as possable........if the hose parts company with the cooler whilst driving, you may not notice untill major damage has been done

Ptfe is not a good idea on the new one, but a bit of anti-seize grease should be ok
ptfe is meant to seal two threads, with the oil cooler connections the seal is the two surfaces that the nut pulls together, sealing the thread would not stop the oil coming out were the pipe goes through the nut, i see it all too many times on diy plumbing unfortunately

Done....

and I think we may have found the issue <see piccie>

Both sides feel much better, no movement from hose, no cross-threading.

But was a bugger to get up due to knackered threads but got there. Took quite an effort to clean out all the swarf from the nut but it’s looking good.

Just need to keep an eye on drippage and oil consumption now !
