Really all you have to do is remove the housing. It's held on by 3 10mm bolts. However, it looks to be a pain with all the other parts in the way. (I have my turbo off so it would be REALLY easy for me to do, but it works fine so fine it stays. I would think you can manage it. I think if you just take your time you can just undo the bolts and remove. Remember though, the new t-stat goes in like the old one, with I believe the spring facing out. What makes you believe you need a t-stat?

Thanks
David
