well i finally got around to installing the 160 thermostat. needless to say i went and beat on the car and all i could muster up was a 176.. then i let it sit and idle in the driveway and it reached a scorching 179. ill let you know what it reaches tomorrow on my morning commute. i would definitely recommend this for anyone.

i will also add that i finished at midnight and its still above 90 outside right now..

welcome to the lower temp V club!! glad to have you as a member. You may see 185 sitting in traffic, but that will probably be it.

easy, all it takes is a 10mm socket and about 15 minutes. i put a giant fan on top of the motor for about 4 hours to make sure it was really cool. i bought a gallon of dexcool and used about about a half gallon of distilled water.

Ok where is the best place to order a 160 thermostat from? And is it the same as the corvette ones?

Linky for the 160 t-stat? Any vendors here have one?

Did you just reuse the gasket or does it come with one?

Do you have to have a tune? My stealth v tune is messed up so I'm running the stock PCM.

A tune is needed to take advantage of a cooler temp thermostat. If you send me a ecm we only charge $75 for the tunes on this car type. $160 if you want me to just ship out a whole different ecm and you get to keep your original one.

If we have a tune from you already, would we be able to take advantage of the 160tstat without a retune or would you have to modifiy the tune's fan settings even more?

This should work, right?

I got mine from a local LSx dyno shop. i paid $29 for it. I assume it's the same as the vette one because the guy I purchased it from said he has one in his vette

Does using the 160 T-stat keep the car from going into open loop or closed loop, I can't remember which one?

Can the open/closed loop thing be tuned?

With a tune the car will be in closed loop. The stock vehicle wont fully be learning until it hits 176 degrees F. So i make it learn at about 150. An un tuned car with a 160 will have issues and wont be correct.
People with our tunes NEVER pay for updates for thier mods. You just cover the exact shipping costs. So if you have them, just send it back with a list of what you changed or more requests, and i set it up and ship them back out the same day for you. :D

Thanks for the info. I use to have a 96 F-body with a 160 and it had problems. I will be getting in touch with you soon to get a tune for my V. I haven't got a CAI yet so I wanted to do that before I get a tune and now a 160 T-stat also.

I should be able to have the Tstats in stock for 35 shipped to your door for those that would want one for thier V.

what about if we already have a tune from you? would you still need the pcm back to make some changes?

07-01-09, 07:18 AM
i would assume yes since the car is learning at 176 instead of 150. and i'm sure there is another change to the tune or two.

I've heard a lot of mixed stories about switching to a cooler running engine especially on more modern LSx's. Anyone have anything concrete to show the benefits of this?

what is your oil temp after doing this?

StewV

first off, you don't need a tune for 160 stat.
after installing my slp 160* stat my temps
never went above 190 in stop and go traffic,
and maintain average temps of 174-182.
( 90* deg. day with high humidity )


oil temps dropped 20* as well.

all of you who don't have a 160* stat should be
the next mod on your list to do.

Got one from Jesse and just installed it... was hoping for way better results than i got. Is it possible he sent me the wrong one? Like a 180 or something?

Was driving around town in the Los Angeles area and it was 98F with low humidity... the car water temp was mostly around 185-190 but fluctuation a lot. Highest it got to was 205F after giving it some gas going up my mountain home. This is a little better than the 220 or so it probably would have been hitting, but still isnt 170's like the thread creator. :(

You absolutely do need a tune to set your fans to turn on and off at the correct lower temps with the lower temp T-stat otherwise you completely defeat the purpose of installing it!

So tested again today but with 75F temps ouside.

On the freeway it was a constant 177F with oil temp of 190F.

As soon as I got off the freeway temps rose to 200+F.

I do have a WFM tune so my fans should be coming on a little earlier (thermostat installed after tune).

I don't think these huge fluctuations can be good.

cooler engines are much happier than hot ones.
hey, but don't take my word for it. what do i know
anyway? i just like installing useless mods and
wasting money in the proccess.

I bought a Diablosport and have had great success in tuning thus far. I'm about to pull the trigger on the 160 stat. Just wondering if you could assist me in tuning - what temps are your custom tunes using for fan 1 on off and fan 2 on off?
