What are stock thermostat temps for renix and newer???

 

Renix I don't know, but the newer ones 195 F (F for you guys in the US), if I'm not mistaken.

 

Renix is 195 aswell, I personally ran a 180 with a pin hole drilled on top with great results ( on my 89 and 95 )

 

stay with a 195 for the Renix and get a mopar one if you can... for the best results

 

This ^^^^^

195 degree stat and from 38 years of wrenching, I have found no more reliable thermostat than an actual Mopar stat.

And they're a buck or two more than many of the crap stats you'll get at many parts stores.

 

Mopar 83501426 only. I went throug 3 Stant Superstats on my 3 Jeeps. never again.

 

bought my OEM thermostat, hoses and water pump from WeRMopar.com.

 

Yeah! Like everyone else said 195deg oem t-stat. I run a 195 all year round and never had a problem. There are some parts that you want to stay oem and the t-stat is one of them.

 

I run a 160 degree on mine runs alot cooler idling in trails or at low speeds. And i dont suffer any mpg loss. Still get 19 mpg highway.

 

I have a 160 currently and hate it. It's never warm enough. Except when I get in trails and buried in mud or snow. But I have my electric fan on a switch so I can turn it on when I workin her hard in trails. I like it. Goin back to 195. I'm always cold. Haha

 

Well i guess where you live is a big part too. Im in SC hasnt touched under 50 here yet lol

 

Use 195 degree. The 4.0L engine was designed to run right at 205-210 and that's where it runs most efficiently which the 195 degree thermostat will insure happens.
