180 thermostat

Where to buy 180 degree thermostat for 2011 5.3.

180 thermostat

Postby tech182 [OP] » Jul 27 2011, 9:05pm

Since I have a Hypertech programmer on order I thought I'd lower the thermostat. The Hypertech will reprogram fans, according to their site. Unfortunately, they don't offer a thermostat for newer vehicles.
Does anyone know where I can find a 180 degree thermostat for a 2011 5.3?
The web sites I looked at don't list one.
Thanks

Unless you are going to do some significant mods I see no reason to lower you fan on/off and put in a 180 t-stat.

I have been on the Corvette Forum for 6 years and have a 96 and 00 vette. Many mods on the 00 and had the computer/tune work done by Chuck at Corvettes of Westchester and due to the mods and the computer tune a 180 t-stat and reprogram of the fas was needed.

This was and still is a very hot topic on the corvette forum but GM designed these engines to run in the 220 range (and from everything I have read lower temps can in some cases hurt your engine and reduce the efficiency and life of the engine) so short of doing major mods their is no reason to change the fan speed and t-stat.

That is JMO and based on everyting I have read and from being a gearhead for 30+ years. I am old school and this was a hard egg for me to swallow at first as I was (and it was hard to break) a firm believer in running in the 170 - 180 range. Matter of fact when I had my 69 Nova I was always worried when the temp went above 185 - 190.

Again JMO.

Got this reply from Hypertech on 180 degree thermostats: "In 2004 GM started using 186f degree thermostats and it did very little good to install a 180f and installing anything cooler caused problems. For this reason we no longer sell lower temp stats for the newer GM trucks."
I'm guessing it's a slow opening thermostat since my truck runs at 210 degrees all the time. I'd love to know what the full open temp is and if there are any that are full open sooner.
Fast Cop, I'm with you on old school. The first engine I ever worked on was a flat-head straight-8 Pontiac.

we just covered engine temps in class last week. a 195degree thermostate opens "partly" at 195 as is fully open at 215.

The way it was explained to me is the higher temps are needed for emissions etc to work properly.I'm 60 and I hate looking at the temp gauge,LOL.

180 thermostat

Postby Jrluz14 » Jul 30 2011, 12:45pm

I'm running the 160* t stat and my engine is consistently 185*. My LS1 fans don't kick on until about 200* and it takes about 2 minutes to get back down to 185* and then they shut off. This is all based off my digital Aeroforce gauge too, so its accurate within 1*.

I have learned since purchasing my 2010 that the new trucks have a dual poppet thermostat which has 2 plungers instead of 1. There is only 1 temperature (196) made for the Chevy/GMC. I am not a fan of high temps either, I have 160 degree in all of my other vehicles. GM says anything lower in the new vehicles would create performance and emission problems. One good thing about the dual poppet thermostat is that you get faster warm up time in the winter because that thermostat allows for recirculation in the engine water pockets until it gets up to running temp. WARNING, if you replace the dual poppet thermostat with a regular one you WILL run hot. Research the dual poppet on the net and see how it works, it is a good concept I just thing GM should have designed to run at lower temps.
