True but the bottom most bolt is a Bi*&h to get to for most people thats why I suggested that route. Also alot of people have had issues with the tstat housing sealing back up even after cleaning and remounting it back right. There have been several posts here in the past about the dreaded leaky tstat housing, that why I usually leave it alone unless it has to come off. Pulling a sc only takes me about 10 minutes now and with it off you can inspect everything else, ie coupling hoses,fuel rail, injector wires,clean the tb without removing it from the sc inlet,check the tv cable adjustment, blah blah blah, but to each there own, do it the way that suits you the best.
