Radiator inlet elbow...possibly
 

does the o ring wear at this elbow, as i have a small weep from the elbow area or does the elbow need to be replaced as well. Looking at Rimmers parts the elbow is stated as being stainless steel ,mine is plastic .Any help or other places to source .It's on a diesel engine.

regards Dave.

Is this the one on the top left of the radiator looking from the front? Mine leaked a little but I just sealed it with silicone after cleaning the mating surfaces.

That's the one.

Yes its plastic, and the o ring can perish, be careful when trying to remove it, use plenty of penetrating oil as the nuts are brass captive ones held into plastic.

Rimmers introduced a stainless steel elbow for good reason.
