Follow the upper rad hose to the engine and that housing there contains the thermostat. It is kind of hard to get to but it depends on you. Be sure to put the spring on the new thermostat TOWARDS the engine.
3 tools should be needed for this job. Screwdriver (flat head), 8mm deepwell socket w/extensoin and maybe some pliers to rotate the radiator hose clamp away from 1 of the 2 bolts required to remove the t-stat housing.
Step 1. Remove the airbox assy. Just loosen the clamp with a screwdriver at the throttle body, a pull back the airbox assy and unhook all the elec connectors. Under the throttle body you will see the radiator hose leading to the t-stat housing. It's a little tricky to get to, but should not be a problem if the hose clamp is not in the way of one of the bolts. If it is, just rotate the clamp by sqeezing it with pliers. (That's the hard part) but hopefully it won't be in the way.
Step 2. Remove the bolts with an 8mm deepwell socket. You'll need a deepwell cuz the bolt on the left is also used to hold a clip for the spark plug wire holder otherwise known as a "stay". REmove the plastic stay to get to the bolt. Then remove the 2 bolts and pull the housing back with the hose still connected.
Step 3. Remove t-stat and any gasket material so that both surfaces are clean.
Step 4. Replace t-stat and gasket. Use gasket sealer with the gasket that comes with the t-stat. Re-assemble everything and you are done.
