How many bolts do i need to take out to get to the thermostat? I think i just need to take out one, but there is the ECT switch, that looks like a bolt, do i need to mess w/ that at all? Do i have to watch out for one of the radiator hose? Will there be any fluids coming out?

 

there are three screws you have to take out. make sure you drain the coolant. and you do not have to unscrew the ect switch, just disconnect it
