Radiator o ring size ?? Anyone?
 

Does anyone know the size of the radiator drain plug o ring ?

bump?

Specs (or a part number so you can search for specs) should be in FSM (link in sig).

Thanks. I got the FSM (from you of course) a while ago. I guess I'm just slow, but where in the FSM do I find the part numbers for the different misc. parts?

Been a while since I looked but, IIRC, you can find p/n's in the exploded diagrams, along with torque values for fasteners. If you can't find it in the FSM, Courtesy Parts has exploded diagrams with p/n's.

Tip O' The Day: Put all the FSM files in one folder. Many PDF readers will allow you to search all the PDFs in a folder.

Yeah, before I bumped this thread I found the exact o-rings on the exploded diagrams, but there are no part numbers. I went to courtessyparts.com, but their exploded view of the radiator is not correct for my model year. This is frustrating.

Nevermind, I think I found them. Here they are if anyone needs them in the future

O-ring for upper air relief plug

21441-5V000:
O-ring for lower drain plug

OP has been patiently waiting two years for these #s :rofl2:

Lol. Think of the future. In 10 years when we the 2029 z34 someone may need to flush their coolant
