Attention: TDR Forum Junkies Well I guess you would say I got introduced a little to my engine today. I replaced the tstat. I was flat amazed at how easy it was, man that was slicker than snot - whip, bam, boom I was done. Now what I did was get both seals and tstat from local Cummins dealer, I did not get the updated part number. As I noticed on a thread posted here (can't seem to find it now but anyhoo) that the updated tstat runs a little cooler and takes longer to heat up. Well I'm a little cold blooded and want heat and want it now. So I decieded that I would see what the swinging water temps were like as long as I have heat heat heat.
What prompted this was she was leaking up by the tstat housing, just purchased truck last weekend and previous owner said tsat seeped a little. His little and my holy snickles it leaks are the same level, but then again I get all bend out of shape at a drop of any fluid.
I tore the housing apart and seen how it goes together, sort of sandwiching the lifting eye inbetween the tstat housing and head. I just sort of shook my head thinking to myself I could loose the lifting eye and probably be better off, I mean one less surface has to be a good thing. I did not remove it but cleaned it up a bit with a razor then smeared some smurf poop on there just keep any "I think I can" leaks at bay. There were not signs of smurf poop from a previous installation so I don't know if I did bad thing or not. I also noticed that when I took out the bottom bolt (gotta love how easy that thing is to reach - NOT!) that there was wetness associated with the threads, so I smeared those up as well. Don't know if the threads actually reach into a cooling cavitity but figured it would not hurt.
I have not ran her out yet but I got my fingers crossed and I'm looking for chicken to appease the diesel gods. My fear is that the leak is actually a head gasket and not the tstat housing but I did see some rust on the mating surfaces of the lifting eye (both sides) so I suspect this was the root problem.
I think I spend around 30 mins with the hood up total - this even included me farting around looking for my fender covers in the garage - I hate it when I get a bug up my butt and shuffle stuff around in the garage - I can never find anything the next time I'm working on something.
Oh well all in all it was a good introduction to my new to me truck.
