i found one, by nismo

i actually emailed the guy at nissanprts.cc making sure he know its VE


This is the NISMO t-stat for your vehicle. It opens at 62C/169F, where as the OE one opens at
76.5C/195F.


is that to cold????? or its it completly fine??? in the winter time it will just take a lil longer for it to heat up???

21200-RS580 Thermostat - Nismo $53.34

 

$53!!!!!!!!!!!!!

Autozone has a 170* t stat for under $20..

 

I first need to ask, why do you think you need a lower rated Tstat?

Just by going with a lower Tstat, doesn't mean you will operate at a lower temp. You won't.

Also, why do you want to operate at a lower temp?

My advice, unless you are insanely seriously about racing, then don't worry about this. Just get a nice Tstat 170 or 180 and you will be fine.

The reason I got the Nismo unit is a long story I don't want to explain it in full right now. I've posted about this in the past. Short and sweet, I bracket race my car and wanted the lower temp. But to achieve the lower operating temp, I had to do other mods such as, manual control of my cooling fans, coolant additives, and removing the AC condensor for better airflow.

 

its crap too. I got one from NAPA and autozone and though they were rated at 170* actually opened at almost 200*. After this test I got a factory one that opens when it should and was actually a dollar cheaper than the NAPA one.

 

Wow..Good info michael...

 

i want one cuz, it makes sense on not making the motor warm up so fast, i would like it to warm up a lil slower, seems like it will be better for the motor, than getting quicker

it just makes sense, idk how to explain, if its not gonna hurt anything why not, i will feel better knowing when i start the car its not gonna heat up so quick.

hers a??? dont flame me

its a general ? why have a t stat anyway?? all it does is allow the motor to heat up quick??? or without one it will heat up WAY to slow and cause problems???

thats why a lil lower stat will be ok???

 

try it and I'll respond in the post of "what happened to my gas mileage"

 

Did your current one fail? I replaced it in March.

 

the thermostat maintains the proper temperature. it's closed when the temp is too low and opens when the temp gets too high. it's not a given that all of the coolant in the system will heat up to normal temperature. it's not very fun in the winter when you can't get any substantial warmth from your heater. no reason for a nismo t-stat, that's some major uncle bens. hell, you can't even see the logo.

 

Aren't most "modern" engines designed to operate at higher temps then the old V8 small blocks?? Either way I would go with the OEM tstat just so my engine oil heats up faster and gets slicker to help lube them cylinder walls.

 

makes sense

 

You WANT the motor to warm up as fast as possible!

Without a tstat, your motor will warm up very slowly in the summer time and will still operate at the normal operating temperature. And in the winter time, it will NEVER warm up, which can cause problems.

I would get a nice Tstat like Michael said. OEM is plenty good enough. B/c if you go with Stant, the 180 and 170 Tstats both open at 180!! It's total garbage. So whatever you get, I'd get a thermometer in a pot of water as you heat the water up to 180. Watch the Tstat while it's in the water to see what temperature it first cracks open at.

My Nismo Tstat opens at 149 or so. And it's not Uncle Bens if you have a very good reason for buying this insanely expensive Tstat. I bracket race my car and launch at a coolant temp of 155-160. To make my car as consistant as possible, I don't want the Tstat opening somewhere down the track giving my motor an inconsistant and sudden burst of cool coolant. I found that a 155-160 launch temp provides the most consistant and fastest times in my VE Auto.

 

learn something new everyday. Thanks guys. Us 's don't always know how stuff works...

 

So how do you manage in the winter Aaron?

 

He lives in the south..

 

I read on some board somewhere on the vast internet that most cheapo replacements actually have smaller coolant passages than the factory thermostat. Another good reason to stay with the factory piece.

I've never verified that with the ones that I have... but I wouldn't be surprised at all.

 

Snow Hill, North Carolina is in the south!?

 

 

NY is like one state away from DE!

I would assume that if it's called Snow Hill, it should at least get cold weather

 

lol, NC hasent really had a cold winter the past year

in burlington it may snow 1 2 times, and just hand around 35



oh well im not even gonna put in a stat now, so it dont matter

 

In the winters my car is just fine. The motor operates at the same temp as in the summertime due to my Tstat. It can get down in the teens some nights. But usually, the days are around 40 degrees in the winter time.

 

My engine coolant temperature guage doesnt work at all .. all the other guages work fine ... Does this have something to do with the thermostat or some sensor not working ... I dont drive the car that many travel miles ( 10 to 20 miles ) in 90 + degree Texas heat!!! But dont like driving "blind" without knowing if the engine is about to overheat. The coolant level in the radiator is at normal levels.... The former owner said he was quoted a $400 bill to have this type of work done but didnt specify what was to be done .... What steps do i need to replace or diagnose the guage .. im assuming the thermostat is working since the car hasnt overheated ????

 

lack of a thermostat caused coolant to burn off in my car. Had to fill it up ever week or 2 because it burned about 1/4 of the total coolant. Once I put an OEM t-stat that stopped. I would rather stick to OEM, 30 or so degrees more than that nismo one isn't gonna hurt the engine any, heck it was designed for it.

The one interesting thing is that when I didn't have the T-stat in, it would go close enough to cold when I was on the freeway that the car shifted automatically to a lower gear (3rd to 2nd in an auto) to allow it to heat up again.

 

Older engines were designed to run around 170-180, newer engines should be 220 give or take 10 degrees, If you run it too cold you wont get as good a burn, and you'll probably loose mileage

 

Tha'ts one thing, and another is that a 12 year old Nissan t-stat works as fine, as a new one (if not better). I replaced mine last year just for the heck of it and once everything was put back together, I did a temperature test. The old one tested perfect, right to the spec. The rubber ring was all cracked, but it ain't matter. It is still in my toolbox just in case LOL

 

i think a lot of this goes under the category of "if it ain't broke, don't fix it."
