I had a radiator replaced 3 years ago. A few days ago I noticed water leaking from the top transmission pipe on the drivers side going into the radiator. I tightened up the the pipe. No luck. It appears to be coming from between the casing and the thin inlet nut on the radiator.
Any advice appreciated.

Cheers Joker

You say water leak, do you not run coolant?

You will probably need a new radiator because I don't think there is any way of tightening the big nut, it is there to stop the fitting turning when tightening or loosening the transmission pipes.
Someone else might have a solution but you might need to wait a while, a bit slow here on weekends.

OK, removed battery and undid 3 bolts holding power steering reservoir to gain access to fitting. using a mirror I confirmed where the leak was coming from. Used a flathead screwdriver and hammer to tighten inner brass thin nut. I managed to turn it about 5mm.Replaced everything and took car out and got it to operating temperature. Seems to be OK.

Thanks for your replies

That's probably what I would have tried but using a spanner instead. I didn't suggest that to you in case it wasn't a good thing to do and more damage occurred. Glad you seem to have fixed it though.

I was unable to fit a spanner as it was channel recessed and I would have had to remove the oil line to the tranny to stick a socket on it.
NeddyBear, the radiator itself is good, just a minor problem with a loose locking nut.
