remove bottom rad hose.
right hand side of the engine, below the coil packs, remove hose, remove two bolts, remove thermostat, clean face (the head, not yours), apply bead of sillicone to new stat, fit, bolt on, reconnect hose, reconnect bottom hose, fill system, bled system using bled valve in drivers side inner wing for main rad, and valve sticking out the firewall near the TB for the heater matrix.
tada.
