Hey Guys since I have not seen a thread like this and thought maybe some nOObs will like to have something like this. This fix is not hard be prepared to get dirty.
Tools Needed:
1. Small Ratchet set with a swivel head. (Preferably) 10mm
2. Pan or something to catch the coolant.
3. Pliers
4. Flat Head Screwdriver
5. Flashlight


Step 1: Let your car cool down. DO NOT open the cap while the engine is hot.
Step 2: Take off the radiator cap. Once the car is cool unplug the coolant reservoir.
Step 3: Start to take of the 2 hoses attached to the T-Stat. You will need the pliers to take off the clamps and a flat head to slide off the hoses.

***** There are 2 ways to do this you can either flush your coolant
or do like I did and just open up the hoses and catch all the
coolant in a pan underneath the car.*****
Step 4: Remove all the bolts holding the T-Stat in.I believe there are 3. This is were the ratchet comes in. It really would be good if you have a smaller set with a swivel head.



**** The Third Bolt is under this elbow****
Step 5: Take out the T-Stat and replace with new one and the new gasket dont forget to put a lil sealent on the gasket. A new OEM T-Stat on ebay runs for about $25 Bucks shipped.http://www.ebay.com/itm/NISSAN-MAXIM...item35b40ab64d Installation is the reversal of removal.
Step 6: Refill your radiator. If your coolant has bits and lil pieces of trash pour new coolant in. You dont want that crap in your engine.
Step 7: Turn the car on and blast the heat. Check for leaks.

dont forget you have to bleed the system, even if you just replace the thermostat and lose ~1L of coolant

other thing is clean around the thermostat housing where the gasket mates to the surface with a razor blade

There is also a water control valve which operates like the t-stat. I dont know about the longevity of them, but I replaced it with my t-stat when I did my radiator.

Where are the bleeder screws on the cooling system?

Just take the cap off and let it run for about a hour. Make sure reservoir and radiator is full. Try doing it where ur car would be on a incline like a hill.

Is this for the 3.0 or 3.5? I have a 4th gen and am looking for a thermostat write up like this for the 3.0, thanks

I am sure the design is similar, if not exactly the same.

Does this thermostat assembly come with a gasket? I bought one today at Autozone, and they said it didn't have a gasket with it.

autozone....yeah, this won't go horribly wrong

This is a great post and it saved my **** back in May... I would go a step further and say that a swivel head for the ratchet isn't just recommended but that it is absolutely necessary. The bolt underneath the elbow is nearly impossible to get to otherwise.

Nope, OP did it wrong. You loosen the tensioner pulley, slip off the belt, and tighten the adjustment nut all the way down, then you have full access to the bolt. Easy peasy.

le sigh, nubs gonna nub

Reallyslowrio

meh, I did it without a swivel or messing with the belt.

I had to use a combination of shallow/deep sockets and a tiny extension I had laying around to get all of the bolts.

Where does this hose go to ? and part number for it please ASAP

tri-valley mechanic

It's the coolant return hose coming off the oil cooler:




It connects to the other end of the metal line that comes off this port on the oil cooler:



Sorry it took so long for anyone to respond to this.

Thankful to you
