2014 2015 C7 Corvette Stingray 160 Degree Thermostat

The C7 Corvette Stingray Lingenfelter low temperature thermostats for the new GM direct injection Gen V V8 and V6 engines are designed to reduce engine operating temperature, increasing engine performance. They are a direct fit replacement for the OEM 212 degree F / 100 degree C thermostat.

The Lingenfelter low temperature thermostats are available in 160 temperature range. The 160 degree F is recommended for high performance applications that also want to maintain better heater performance in the winter time.

Note that the Gen V engines have the thermostat assembly located on the hot engine outside of the cooling system loop. Because of this change a 170 degree thermostat in the Gen V engine, is more similar to a 160 degree thermostat in a Gen III or IV engine where the thermostat was located on the cold side of the engine inlet cooling system loop.



- Engine and chassis dynamometer verified performance
- Direct replacement for the OEM thermostat
- Fits in the OEM thermostat housing
- Easy to install
- Reduced engine operating temperature while in thermostat and not fan or airflow limited control
- Increased power

Installs directly into your OEM thermostat housing part number 12657137 which is not included.

Your website doesn't mention whether it fits/works in an LT4 Z06 engine. Inquiring minds want to know?

I've always wondered, if a 160 degree thermostat means better performance or longer engine life, why don't cars come factory-equipped with one. I put one on a C-4 years ago, and didn't notice much difference. Yes, the coolant temp read lower; but that's about it.

If there's any good reason to run the engine at a lower temperature, I think GM would have put in a lower temperature thermostat. Here's my opinion.



Until you provide independently verified benefits from using a low temp t'stat, I think you should be barred from selling them on this forum.

He's been here a LOT longer than you newb.....Opinions weren't asked for either lol...These are good people got it?.


You don't have to buy it....nor like it.

Maybe someone can answer the simple question: Why don't cars come factory-equipped with 160 degree thermostats? Maybe it's related to emissions? Surely somebody knows.

motomanvette

That and the car has to run emissions friendly in cold states. A cooler stat keeps the engine from warming to optimum operating temperatures on a real cold day. The stock stat is a 50-state, emissions friendly compromise.

Of course its related to emissions, hot temps, hot air = leaner fuel requirements. Cold = richer fuel requirements, oil contamination etc.
Also water temps below 180 relate to poor expansion and contraction property's which the block and heads and probably everything inside need for longevity, oil control and wear.

Then my impression is, a low-temp thermostat is probably a bad idea unless you live near the Equator.

Do u have in stock.?

Do y'all really think the feds would force GM to do stuff to their engines that make them run worse?

Looks a lot like the thermostat For . . . errr, Brand X runs in their 4.6 minus the bleed hole.

A question (actually 2):

Does a 160 degree thermostat ensure that the engine runs at 160 degrees all the time?

Wouldn't a C7 with a 160 degree thermostat have a chance of failing an emission test?

Thanks,

I believe the thermostat opens at the 160 mark, thus starting circulalation earlier. Temps may certainly exceed 160, if they fall below 160, it will close but such things as outside temp and the efficiency of the cooling system and loads on the motor would be responsible for the temperature range. Switching to the Z06 Grill may actually be more advantageous as it can flow more air.
I don't expect miracles based upon a thermostat change. What i do find interesting and have yet to research is the coolant that can replace the water/glycol mix. If it's a thinner viscosity, then there would be less parasitic loss from the water pump. But like nitrogen in the tires, may have only modest gains...
