Greetings everyone,

Does anyone know the exact size of the o-ring that goes in the hose fitting that attaches to the very top of the water pump? My fluid is leaking from there, and I'm pretty sure it's the o-ring that is bad. I really don't want to fork out $160 for the hose at infinitipartsusa.com to stop the leak. This is the part number, I'm sure it comes with the o-rings...
Q45 Inlet Hose Part Number: 21170-AR000 2002-2004, #3

I'd much rather replace the $5 o-ring.

Any tips are greatly appreciated!

All the best,

Pretty sure if you get one of those multi-o-ring kits, you'll find something, but if you can baby your leak for a few days, here's OEM. Shipping is expensive, try a nearby dealer even nissan.

Thanks @ EdBwoy... I did wind up buying an o-ring assorted set. I put one on the end of the hose and tightened it back down. I can see the o-ring I added got flattened out and is even sort of hanging out the side of the part now. It kind of looks like a liquid gasket!

Leak stopped completely. I also pulled the hose from a M45 at the junkyard, for when my shade-tree fix fails, swap in the new (used) hose.
