Yep, definitely go to Nissan dealerships for parts. I'm pretty sure I did the same when I got those parts. I know I got the ATF fluid from one, and it wasn't horribly priced.

Have to do this to my fx also. Been slacking on the coolant flush.

Ok. So we just had a fun DIY coolant flush mini meet with Nnaji (Goldman ). Sucks that my ordered no spill funnel was delayed. Nevertheless, we went through with the project.

It's so low that I can't access removing the underbelly pan.
I figured it does not really affect the flow since the drain is on the bottom of the radiator and no component in the system is elevated higher than the drain outlet. Is this bad practice?

Just an FYI Even using the bleeder and the trick funnel set up it took a week or two of topping off coolant to get all the air out of the system completely.
Haha, had fun with Ruben doing the coolant change!
Only troubles we ran into were the air bubbles in my system.. But Ruben massaged the hose for quite some time and he bubbles were gone!

You should be able to get more old coolant out if its not jacked up. With the front end jacked up, the coolant that normally would drain out from the block won't be able to since it tipped higher than the radiator. It's nothing major really. Just try to get as much as the coolant out if possible.

I did it when my coolant in the reservoir got dirty and had dirt or something in it. It was turning red like iron from the metal pipes, which had rust when I removed the hoses. It was probably around 100k miles. I'm guessing it's either a 30k or 60k interval, depending what schedule you like to follow. You can buy antifreeze that is rated for mileage as well, like 100k or more.

I did the flush as well since I figured I had crap in they system and replaced the two hoses and radiator cap. The flush is just draining the coolant, then filling with distilled water and running the engine so it circulates. I think you can feel one hose and once it gets hot you know the thermostat opened and circulated. Then drain it out and fill with fresh coolant. There should be DIY's you can follow. I think I used the factory service manual for that and then getting air out afterwards.
I test the coolant with a Prestone Antifreeze/Coolant Tester to determine when I need to change my coolant in additional to visual inspection of rust and sediment.
How I do a coolant flush at home. It takes a few hours with this procedure. I know when I'm done, I got all fresh coolant in the engine block and radiator. There are a couple of plugs on the engine block you can remove to drain the coolant quickly, but they are hard to get at without a lift at home.
Stuff you need:
1) 5 gallons of distilled water
2) 2 gallon of 100% concentrated coolant.
3) A Prestone Antifreeze/Coolant Tester (http://prestone.com/enca/node/387)
Drain and fill with distilled water:
1) Drain the old coolant from radiator drain valve.
2) Refill radiator with distilled water
3) Run the engine until the lower & upper radiator hose is hard filled with coolant.
4) Let the engine cool down enough and its safe to open the radiator cap without coolant shooting out at you.
5) Repeat the steps until the stuff comes out of the radiator is clear (about 4 times) or clean enough to your standard.
Now that I know that the engine block is filled with distilled water, time to refill with 100% concentrated coolant:
1) Drain the distilled water from radiator drain valve.
2) Refill radiator with 100% concentrated coolant.
3) Run the engine until the upper & lower radiator hose is hard filled with coolant.
4) Let the engine cool down enough and its safe to open the radiator cap without coolant shooting out at you.
5) Repeat the steps until the coolant concentration is at the proper level using a Prestone Antifreeze/Coolant Tester.

I didn't have spike temps. I think it helps that the car was cold and left untouched overnight. Nnaji had a lot of air bubbles trapped in the hoses. He had been driving the car all day.
I had to top off the reservoir tank at least 3 times since the level dropped below or within minimum level.
