Mike, no part # appears. The image isn't showing up...

 

Really? The image works for me though. Here's the image + part # again.

Part # 21481-89900

 

Cool, thanks. Don't see it again so it might be my IE at work that's blocking something out.

 

Most likely. Anyway, just walk into a Nissan or Infiniti dealer and give them the part #. The o-ring is tiny and you'll need one for the air relief plug and one for the coolant drain plug.

Just for kicks, here's the url to the picture. Maybe the url may work...who knows.

Yep, the URL doesn't work so it's my company's paranoid system...

Thanks for the info. I ordered mine but haven't had a chance to go pick them up, I will try today. When I go in I'll check if I got the same part #.

 

No problem. Good luck.

 

Ended up doing the coolant change today though it went a little different...
1. After refilling I let the car idle to warm it up, rev the engine a few times and eventually shut it off. The needle on the gauge never went up past the mid point.
2. After the car cooled off a bit I opened the rad cap to add more coolant but nothing had dropped.
3. Decided to let it warm a little longer and again did a few revs. It idled for 5-10 min and again the needle never went past the mid point. I turned the heat on and there was cold air blowing.
4. Went for a short drive. As I started the drive the cars fan went on and then the needle started to climb. Climbed to the 3/4 mark after which point it started to drop back down to normal range. The heater was now blowing hot air.
5. Had the car parked for 10-20 min while I went to a store, drove back home and the heater was working fine, temp stated in normal range, and no more engine fan going off.
6. Let the car cool off and added more coolant.

Anyways, was driving the car something I should have avoided to get the thermostat to open? Just curious because idling alone didn't seem to be doing it.
