Sealing problems on oil cooler lines

[TURBOV6]

I"m having problems sealing it to the factory oil cooler, both the top and the bottom, it not leaking at the threads. The oil cooler lines are new. Should I put a "O" ring?

back to the top!

Being you said top and bottom, would "assume" you mean at the radiator?

If so, wrap the threads with teflon pipe tape and tighten in stages. Wait a few minutes between the final stages of tightening. Then do the final step when hot.

The end at the adapter uses o-rings and they could be damaged or gone.

Its the stock cooler, and its new lines from GM. Its not leaking at the threads and the side with the rubber O rings is at the pump. I did let it warm up and retighten it but still leaks. There is a flare fitting on the cooler side it might not be seating on good. Its a new radiator but don't know if its a original.

sup jackson thats kinda weird, cause i just pulled my lines when i had my rad recored. i would say use an O ring since its not comming from the threads.

You're saying that the lines at the rad are leaking,past the flare?I hate to say it,but O-rings and tape aren't going to seal a tapered flare with any kind of reliability..It almost sounds like G/M subcontracted their replacement parts to a second rate manufacturer.
I did my upper cooler line a few years ago when it started weeping and it's been as solid as a rock.Used new fittings,hose,the works.If you've got a hydraulic repair[airport maybe,you are in Hawaii?],take your old fittings and have a new hose crimped to them,with the proper fitting orientation of course.It sounds like the replacement's got some bad flaring.I'd take them back for a refund.

well if that is indeed the problem check out hydra air by the airport. they will have everything u need, they had all the fittings i needed when i was doing airbags on my truck they are the best down here.

There you go,but if that doesn't pan out for you,try a farm equipmant repair and sales place.They do a lot of that as well.
