Temperature wise I haven't seen more than 190 degrees. It takes 170 for my edge juice with attitude to come alive and I haven't seen much more over that. Last summer I could barely get it to 180 and I can hit that in no time now.

Don't remember the part number right off hand. You'd just have to call a parts store and find out. Mine is a 01 lb7. Took about 30 minutes to do the job. Just make sure you put coolant back in.

No problem. Glad to help out. I just drained it out low enough so it was underneath the t stats so it wouldn't make to much of a mess. Loosen the bleeder screw on the top of the housing before you do anything to let the air out.

Drained it from radiator drain plug. Put some new in when I got finished cause the only drain pan I had was for oil. And honestly I find most of my stuff out on YouTube. I'm sure there is a bunch of guys here that would crucify me for saying that but YouTube has been a life saver for me with my vehicles.

I love YouTube for that reason....swapped stats out and I could smoke a pig in there now....damn it's hot...15-20 min and it was done. Thanks for the help, I'm pretty mechanically inclined but diesels as much as I love mine scare the hell out of me!! Thanks again!!!
