OK i HAVE LOOKED AT THE SEARCHES AND FOUND NOTHING ON THIS QUESTION I AM ABOUT TO ASK. WHICH WAY DOES THE THERMOSTAT GO BACK IN THE HOUSING. dOES THE LONG END GO IN THE BLOCK OR THE HOUSING END.? YES i KNOW I SHOULD OF TAKEN A SECOND TO LOOK . I THOUGHT I DID BUT I AM NOT SURE NOW.

 

 

James, that looks like it's for a RWD setup. This is for our setup:

 

Ok kool. Now I have a problem. Is using a stock nissan t-stat the only way to go? I bought the oreilly t-stat but my gage went to half way on my gage and then there is no heat. I do have the car at an incline to help ther bleeding of the system so is the nissan t-stat a must in these cars?

 

i dont' think it should matter but i do know there are 2 different t-stat for our VG. I usually buy the t-stat at the dealer, its a few dollars more at the dealer but you know its an OEM part and you can never go wrong with OEM on any car.

 

I believe James' diagram is correct for the VG...atleast on my VG.

 

I've never had a VG and don't know anything about them so that may be the RWD setup for all I know

Whoops, I just Googled VG30E thermostat

 

The diagram makes it look so easy.

We've got a 1994 and it never has warmed up all the way, even with a sheet of cardboard blocking a lot of the radiator.

I'm thinking about replacing our thermostat - though the left front wheel well I would think -

How big of a job is it?

 

Its not that bad of a job even though I am not done yet. Just moving some of the wiring and such isnt to bad. i am picking up the t-stat in the am. The location of the t-stat is more accessible from the top than the wheel well housing.

 

Well the t-stat is done right along with the radiator cap. The car has heat now and I did the inclined bleed for the cooling system and it seems to be good for now will have to check the system in the am hopefully.

 

yea that's what the Z31 is setup like. Tho, i did try test-fitting a 3rd gen intake on it once...

 

I haven't had to do the inclined bleed in a long time... but i also had a few things bypassed (throttle body, UIM) so that might have something to do with it. My bleed valve on the UIM no longer does anything.

 

Damn talk about a finicky car to work on, damn....I thought my Integra was bad but these nissans are certainly a horse of a different color. Now I am going to have to take the radio out so I can work on the heater control unit because the lighting in it keeps dimming on it and then no heat, but as soon as I put my fingers on the harness that plugs into it the illumination comes back on and the heat starts to work again....ya the joy of wiring...not

 

you have auto climate control?

 

Yes I have the auto climate control. Well after taking the console apart this morning I am very unhappy with what I found. The wiring harness plugs and the male connections on the unit are all corroded. I took the unit apart to clean it the best I can and then put some corrosion spray in it for a bit and wiped it clean as much as I could get out. And so far the unit is working well but I think I will still be looking for a new or a better used one to replace it with...
