The shop owner sent me a message stating that if he didn't charged, it wasn't replaced. So, I believe they keep it for themselves or sold it to somebody else...way to go!!!! Anyway, I'm gonna buy a Nismo T-stat and a new fan w/ fan shrouds to see how it goes. I did put the T-stat in boiling water and it took approx. 5min. w/ 30 sec. to start open. Is this Ok!
