StantOE Type Thermostat, stainless steel

Very good value for price. I had a shop put a new water pump and thermostat in my 2006 Dodge Ram 1500. They used the OEM 205 degree thermostat which caused the truck to run warmer than usual. Temp gauge would stay at half or climb about 1/8” above half. When towing uphill a steep grade with a loaded trailer temp would rise to about 3/4 or higher on the gauge. Now with this thermostat temp stays below half about 1/8” and driving the same grade reaches to about half but doesn’t go over. Pretty easy to install if you watch the 1Aauto.com website video on how to replace the thermostat on these 2006 5.7 Hemi engines. Used a 13mm socket and an adjustable pair of pliers for the hose clamp. Would recommend.

The cooling fan in my Jeep SRT8 blown!! It was a garbage knock off that some previous owner installed in her). I ordered a oem mopar cooling fan (expensive as f…….) but is what it is. The Jeep was always running with the needle between 210 - 215°F (factory 203°F thermostat). I ordered this stant (motorad) 190°F thermostat (I didn’t go with the 180°F one because it needs a custom tune to start the fan up at early temperature, it will turn your check engine light on otherwise). I also ordered a new gates water pump and radiator hoses. Difference is night and day!!! temps stay between 196 - 203°F while you driving and statically at 198°F on idle (under inclement Florida summer about 91°F). MAKE SURE TO BLEED THE COOLING SYSTEM PROPERLY!

This Thermostat works great. Before the install my car temp would stay around 212-213 degrees while driving. Now my temp rarely goes over 196 degrees. Installation is simple. It's only 2 bolts on the flange then you just pop the old one out and pop the new one in. Easy peasy. Note: make sure you put the plunger in the correct position or the thermostat may not work properly and may cause your engine to overheat.Side tips: you can use a 1/2" socket or I think a 13 mm maybe. Also I recommend romoving your plastic engine cover and also removing the electrical connector from the air intake tube for easier access to the bolts. Furthermore I myself added a fel-pro thermostat gasket because my old thermostat was leaking coolant. The Thermostat does have a rubber seal around it but I wanted the peace of mind to know it wouldn't ever leak again.Good luck to all and safe travels.

First of, one star taken off for poor packaging.The thermostat came with the gasket already attached, which is good. Some of the reviews indicated no gasket.One reason i bought this to replace my old one is because, my coolant is leaking from this area.The installation went fairly well and easy, and so far no leaking. Only time will tell.

I replaced my water pump and thermostat at the same time, using this thermostat to help with heat soak power loss in the warmer months. So far so good, the temp stays a few ticks lower on the dash and no hiccups or temp swings. I have minimal mods with a canned 93 octane tune, and I haven't had any codes/dummy lights.Do yourself a favor and Youtube how to install a water pump or thermostat for a Hemi if you've never done it. It isn't overly complex, but it helps to see how everything comes apart before doing it yourself.

as you know 212° stock is terrible for the motor ! this thermostat keeps my ram at solid 190-192 in 100° weather. awesome mod

Purchased for my 2005 Hemi Ram that resides in the hot Phoenix desert. Same size as factory replacement. My stock temp 203 Stant I put in 40k miles ago looked brand new still and looked identical to this 190 stant. I decided to try this as I tow almost everyday in 100 degree weather with my ole girl and wanted a little buffer room for those hot days. So far it has worked great keeping me 10 degrees cooler than before on these hot days. I would easily purchase again.

I ended up going for this to replace my OEM Ram 1500 thermostat because it was rated for 190 degrees and I wanted to run cooler temps in anticipation for my new headers. Worked great for about two months and stayed around 188-195 F. After two months it would not open until 230-240 F and would sit at 204-215 F. My coolant was completely changed when I installed the thermostat. I ended up having to take it out and had to drain a bunch of NEW coolant. Went with a different 190 F thermostat.Pissed does not describe it. OEM Mopar coolant is $25 a gallon. Made this basic maintenance job more expensive than just going to the dealer.Also, its not even a Stant, its a Motorad. Its false advertising. Motorad is a crap brand.
