Hi guys, Now that it is getting warmer out there, ANY way we can keep underhood temps down is good. Cooler everything, makes a happier supercharged engine.

So i have some 160 thermostats ready and in stock for those of you guys that want them. $35 shipped to your door is all im going to charge for them.

Thanks Jes

Is this something that is easily installed and keeps the fan going after I park the car?
Texas weather is the pits for heat! My porsche will turn on and off the fan until the engine compartment is cool enough.

i think almost everyone would agree with what w4m said; so why don't cars come with 160 degree thermostats from the factory?

No this is a physical valve that goes into your waterpump housing to allow for more water flow at cooler temps. It is a easy install, but only while the motor is cold. Hot coolant on the hands hurts. :) The cooler Running Fans are part of my tune. I can modify the program to target a 184 degree running temp instead of 194 i do with the stock thermostat.

Please correct me if I'm wrong, but a 160 stat just means it opens sooner that say a 180. When the coolant temp hits 160 the stat will fully open allowing the coolant to start flowing instead of waiting for it to hit 180 degrees. Now once it is open, it will then stay open untill the
coolant drops below 160 degrees. So, on a summer day or anytime when the engine hits operating temp, the stat is open, and will
remain open. Therefor does changing a stat without programming the fans to come on early, really accomplish anything?

I can see it helping with your tune turning the fan on sooner.

Stock is 194. While you are driving, the fans shut off after a set mph anyways, so then the air going thru the radiator will continue to be cooled and the engine will except that cooler water until the 160-170 mark is met and it starts to close itself. Any thermostat still allows some water to pass thru it, There are holes on the valve that allow that extra flow.

The advantage here is, Cooler temps at low speeds and idle, and alot more while moving. With or without a tune.

A tune Does however provide more cooling when acompanied by this mod as i can turn the fans on at 165 and keep cool air going thru the intercooler water core and radiator.

In answer to surgin's post, the drivetrain is designed to run at 185 - 205 degrees. The engine controls, sensors, and cooling accessories are calibrated for that setting. The old wives' tale is that running an engine cold is somehow going to "boost performance", which is very far from the truth. Yes, the engine runs colder: the fuel/air ratios are slightly richened to compensate for an engine which never warms up to design temps. The oil and engine metal remain below 200+ degrees, so the crankcase combustion byproduct volatile acids and condensation moisture never vaporize in order to be burned by the PCV system. Cylinder wall temps stay low, so there's more raw fuel to wash off lubrication. Automobile manufacturers have absolutely no idea how to design and run an engine, so we must make it better. We have learned exactly nothing in 126 years of engine building.

You can buy thermostats for $7.95 at NAPA. Any temperature you like. Any car you like. ("Yeah, but, Sub, How come boat engines run at 140 and 160 degrees ???" - "Because some boat engines are raw water cooled, and to run them at 205 causes incredible scale in the exhaust cooling systems. The fuel systems are designed accordingly and the crankcase ventilation systems are impressive."

Sub, My car runs at 220 all the time in stock form. Also, while doing a full throttle run from idle to 180mph, Guess how high my coolant temps where at that point of letting off the gas?

The car is happiest at 175 degrees from what i have seen as is why i leave the fans to keep it near there.

As for a 7.95 thermostat at napa, What is the part number for the 2009?

Maybe i am not reading this right, but seems he is saying its not good to run the lower temps.... what am i missing? seems when i run my vehicle it runs best the first 10-15 miles after start up.

Ideal running max running temp is about 185 from my experiance in high liter motors.

I always find it so funny how the debate over cooler thermostats keeps raging on. YOu either want one or not and they are now available. Awesome Jesse, I definitely want one.
I can tell you, it was found on the C6 Z06 that after a certain coolant temp, the ecm starts pulling timing and fuel and what ever else it does to keep the engine safe. By replacing stat with 160 unit, on the highway I would see cruise temps of 172 or 174. At idle I had the tune turn the fans on sooner so it would run cooler there as well. So, does a cooler stat directly make the car faster? NO. But does it indirectly? YES. Because the ecm won't start making the engine run safer because the engine is not getting too hot.

Thanks for listening,
Mark

Mark,

I understand the concept, however if that is the case, why don't they put
in a 160 Stat from the factory? Once it is open fully and the fans engaged,
it should no longer come into play unless the engine needs to warm up again.

I must be missing something, I admit my knowledge in this area is limited,
but I have always heard that cooler is better. In fact in my younger days
I recall taking out the stat in my 327 - 65 Nova in the summer. We ran
no stat in the summer and replaced in the fall when we wanted heat!

^ You can thank the epa/emissions standard for not putting in a cooler tstat in from the factory. It all has to do with emissions and not performance.

Yes i can throw one in for you Surgin. Im still waiting on the part number for the napa tstat, so then everyone can get them for 7.95.. It cheapest i have seen was 30 plus shipping. So i bought 10 of them to save on shipping. Then sellin them to you guys for the same price.

With the motor running colder, wouldn't that make it possible for it to form hot-spots, and will fuel mileage change, or does the computer calibrate the engine to burn the fuel at the new lower temperature?

Prof

Just my .02 cents worth...

I run a supercharged engine in my SRT 10. One of the characteristics of the pcm is that as the intake temps rise the pcm starts to pull timing to inhibit detonation (the beginning of the end in a supercharged engine).

While I am new to the CTS V world, I would bet that with cast pistons and rods, there is a similar program in the LSA engine. Heat is fine to a engineered point...then performance is adversely impacted intentionally. Timing is pulled, in effect raising the percentage of fuel in the air fuel mixture (enriching) which creates a corresponding decline in the temperature of the air/fuel mixture.

I think in normal operating conditions there is very little down side to temps up to 250 or 260 in modern engines...if you are hot lapping at the drag strip, those kind of temperatures will cause your pcm to extract timing and lower the performance of the vehicle. Continued operation in boost at high temperatures will cause detonation in the cylinders and can severely damage pistons, cylinder walls, rods and will eventually create a window in your block.

My opinion is that the real cooling factor is the temperature at which the fans are activated. That can be programmed and if you also have a lower activating thermostat that will also help.

If you are driving as a daily driver and not spending your weekends at the track, the lower thermo won't hurt, but the advantages are minimal.

If you are at the track...think in terms of a larger intercooler, or water/meth injection...

But I am often wrong, and I have never stayed at a Holiday Inn Express...

I may be talking out of turn here, but don't higher water temps effect emissions? I read a drag racer's theory that the car made maximum horsepower just before it melted. In the old days we didn't care about emissions and changed all kinds of stuff, including lower temp t-stats. Realistically, the engine will heat up to whatever the cooling system and ambient temperature and the amount of pedal to the metal is happening at the snap shot point of the temperature reading. The faster the engine heats up it seems to me the sooner it gets out of it's rich mixture and into normal running, but maybe with modern fuel injectors and computers that isn't an issue. I could be full of it as well! But-I am lovin' my 09-V so far and am trying to figure out whether a performance tune will effect warranty.

I had one on my C6 Z06. With the hot summers and the extra heat that a modified motor makes, it was a nice addition. Always good to know my car was being cooled sooner. I will definitely be ordering one of these, as well as some other goodies once I can get a chance to talk to you Jesse about my options.
