Here is what I did and how I did it...You can obviously do it however you want as this is only how I did it and should be only used as a guide!
JET 180 TStat #10183
Zip Lock Freezer Bag
Big Black Garbage Bag
Ratchet and Socket
Ok, Lets get started...
First locate where the tstat will go...In the 5.7 its directly under the TB on the left!
I pulled off my air intake so I would have easy access to the 2 bolts!
I placed a big black garbage bag behind it, just in case it started gushing out everywhere!
The I took a Zip Lock Freezer Bag and held it under as I removed the bolts!
Quite a bit came out when I unbolted it and pulled away the hose and then when I popped the stock tstat out some more came out as well! I just let it all go into the bag although some did miss and get on the driveway!
I then put in the 180 tsat!
Attached the hose back!
Made sure it was all tight!
And finally put my intake back on!
That was it...Piece of cake!
Total time was 15min or so!
Like always this is just how I did it...I take no responsibility for you!
