the radiator filler neck is leaking coolant and needs to get replaced, just looking for suggestions or is it difficult to do?

I know that in my neck of the woods I had to buy the whole upper hose when I broke the "T" from the stealer rather than just replacing the thing, it cost me $55. Simple fix just make sure to add coolant and bleed the cooling system after the replacement.

What engine are we talking about and how many miles are on it?

I'm in a bind. We had a pressure test done on our 2000 D 5.2 and we found the filler neck has a leak. The only supplier online I have found that has this part is A1 Auto and it's not in stock. Does anyone else have any ideas. I'm going to try and look for a salvage yard and my last option would be to go to the dealer.

I found this aftermarket part from Moroso. I'm calling Jegs on Friday to make sure that the diameter I need is 1.5".

Just measure the inside diameter of the hose. 1 1/2" sounds about right though. All dealers have different parts costs. I think I just got screwed on my hose.

Cool man - thanks! I plan to take the hose off to measure before I order the part, just in case. ;-)
