If it's the 60degree head....piece of cake. You got one at the top of each head. Easy to get to and service.<br /><br />If it's the 90 degree cross flow, it's a little harder to get to. The t-stat box sets below the exhaust cover. Three bolts holding it to gether.<br /><br />Which one is yours?

on top of each head are the thermostat covers (they have hex heads 13/16 i think) remove these thermostats springs ans seals are there you may need to pry seals out to replace
