my efan is setted to 160 the t -stat 180 is installed... and i drill that hole with the exact same size (check valve) and the temp almost join the half temp on cold weather...i tested the coolant and i it show the maximum...maybe my coolant is 100% pure...i will flush it out again ...and add a 60/40 new mix.

 

my stocker was 195

 

Great write up with pics for proper direction of the t-stat!

 

Your welcome! Glad this write up was able to help so many people.

 

helped alot for me this should be a sticky

 

Just did this today. Hardest part was they put the clamp on the lower radiator hose right in front of the bolt so I could not get a socket on it...had to use an open end and it took a little bit of time...lol

 

Hello I got a small question. I have the same issue with the gauge. as shown on the image low temp. Whats is the exact issue A. is it thermostat B. Tempeture sensor or C. Tempature sending unit ? Please Help me with this issue ?

 

this is an old thread and probably a stupid question. but do you have to drain all the coolant to install this new thermostat? and is there a 180 thermostat that anyone recommends other than the NAPA one that needs modifying. i would want one i could just throw on and not mess with. thanks

 

Yes you have to drain the radiator but it's pretty simple and straight forward.

 

Nice write up
Did u have a hot temperature issues? Or what was the reason to remove the temperature sensor?
