(My first post on forum) I have a 2014 Base Coupe. I searched the forum and found lots of posts on different thermostats. I was interested in getting the Mishimoto 160...it looks like the only one that is even close to the OE design. I contacted them and they told me that their thermostat was for the 2016 and up only. They would not say why it would not work in the 2014. Is it just the temp rating is to low? The other brands of thermostats cover all 2014 and up. From what I have read the physical dimensions of the thermostat is the same on 2014 up Vettes. I'm guessing there are plenty of people with 14 and 15 Vettes running the Mishimoto 160 without any problems. Thanks for the help.

I had one it worked. Until the rubber gasket in it failed.

Thanks for the reply Bruce. Your profile doesn't say what year your car is. I was wanting to know if it worked specifically on a 2014 and why Mishimoto says their thermostat only works in 2016 up cars. Their website says it's for 2014 up Corvette, but in the specs section it says 2016 up? VERY CONFUSING! Also...Did the gasket just come loose? Did you get a new one? (they offer a lifetime warranty).

I have a 2014. Sorry about that.

They designed it on a gen6 2016 Camaro SS is likely the reason. Like most their products, they've begun to have failures and show flaws with a little use and age.

Thanks for you input. I don't think my car has any bad issues. I just don't like the 212 factory thermostat. The car running 220 all the time just feels to high to me. I guess I'm stuck in the old days! My car in summer, sitting in traffic with air on gets well over 220 before the fan comes on high. It feels like its about to overheat and it makes me nervous. If its bothering me that bad, I guess I should step up to the LMR thermostat housing and a Dewitts radiator! If I just do the thermostat, can I have the fan programmed to come on high just a little sooner? Like maybe 210-220 instead of the 235 range? Can anybody recommend a tuner in Middle Tennessee (Nashville)area?

160 thermostat here on my 17 GS. No issues yet, installed 6 months/4k miles ago

There are several thermostat threads here. One thing I will add is that I took the Mishimoto and pressed out the 160 bulb and replaced it. It just lightly pressed in. I replaced it with a 170 bulb from another stat and I am very happy with it. I had tried and 160 and for me, it was too low and in the winter the cabin did not get warm from the heater.

Of course, without a tune your fans will not turn on early enough and in traffic and at stop lights the engine quickly goes right back up to 190 where the fans are set to kick on.

Mishimoto is garbage. Junk products with mostly made up testing stats. I would stay away.

I've had a Mishimoto in my 2015 Z06 for over two years, no problems. Works just fine.

I had one in my '14 Z51. It's still in there with zero issues. Installed it almost two years ago. I also have one in my current Z06, no issues yet.

Keep in mind tho, going with a 160 will not get rid of those 210-220 degree temps on hot days. it will run cooler on the highway but in traffic and spirited driving, the temps will shoot back up. Even with a tune, it will still run a lil warm.

So what's needed, a new bigger HX and surge tank or?

NRB14

Thanks for all the feedback. I see that some people have had good experiences with the Mishimoto T-stat. Some have not. I did notice they have a lifetime warranty. I guess if it fails you can at least get a replacement. I have looked into getting a tune. The fan settings on the C7 seem to be a little more complex than most cars. Can anyone tell me what the settings they used are? For example, did you set the fan to come on in the low setting at 190 then maybe medium at around 200 then high speed at 210? I haven't found any posts that get that specific.

There are many reasons why these cars run hotter but the main reason is, because there isn't enough air moving through the radiator. Most of it which is blocked off by the brake ducts. The fan is only partially shrouded to leave room for the hood vent (which is a joke and doesn't work like GM claims - imo, take it off and the fan will blow the hot air out the vents)

The radiator is good so I would look at doing a dual fan setup like the D3 performance one that has a custom shroud and another HX. Just my opinion here, no cooling issues for me so far tho.

Let us know when you are ready, we have some in stock and ready to ship.

Thanks GeorgeR for your input. I have a 2014 Base Coupe, so no brake ducts, HX or surge tank. I didn't think my radiator was a problem. My car cools off no problem once the fan turns on. (BTW, I added the Z06 cooling fan that pulls a lot more air than the standard 500 watt.) What I don't care for in the factory programming is that the fan does not come on high until the car reaches 235 degrees (I think that's right). That is pretty warm -compared to what I am used to seeing a cars temperature run at. It is my understanding that these temps are considered normal for a C7. But, I also know that high heat can greatly reduce the life of engines and transmissions. I just would like to see my car run a little cooler....that's why I was asking about a tune to get the fan to come on a little sooner. Thanks again for the feedback. I'll look into the things you mentioned when I get a Z06!!!!

GeorgeR_Zed06

A tune will help so you an turn on the fans a little sooner but then it will void your warranty.

The 2015 has a 194 stat from the factory.. 90 celcius

BJ67

Not true, I have a 180 stat ( switched the bulb from a lingenfelter stat to the OE stat) and had the fans turning on sooner with a tune and my car never see's more than 195 degrees in dead stopped traffic in 1/2 hour segments in 90+ heat. Also, that's with a water wetter additive and just 5 to 10 % antifreeze.

NRB14

Thanks BJ67. I was going by the Mishimoto website that says OEM activation temp was 212. No doubt, they could be wrong. The info you gave was what I was looking for. Do you remember the actual settings your tuner used, things like the percentages of fan speed at certain temps? I would like to be able to discuss those with the tuner that I get. Also, I assume in 90+ heat you were running the A/C. My car currently runs (in the summer heat) 220 basically all the time. In traffic (with A/C especially) it will go above that before the fan goes to high. Although, it cools back down to 220 quickly (the Z06 fan works great!).
