Do this when the engine is COLD! You will need the thermostat, gaskets and gasket sealant. The basic method is... Locate the Thermostat housing. On your vehicle it should be on the gearbox end of the engine. To check, find the largest hose at the top of the radiator and follow it back towards the engine. Drain the coolant from the system into a suitable container. If there isn't a drain plug fitted in the bottom of the radiator you will need to remove a hose from the bottom of the radiator. Remove the bolts holding the housing in place. They should not be in that tight. Remove the old thermostat. Clean the area where the old gasket sat. It needs to be bare metal. Stuff a small rag in the hole to stop any rubbish falling into the coolant system. Fit the new thermostat with the spring end going into the engine. Apply a small amount of sealant to the face on the engine side to hold the gasket in place. Apply another Small amount of sealant around the whole face of the Housing. Refit the housing. Tighten the bolts by hand then tighten to the correct torque setting. (17 to 20Nm, 12.5 to 17ft/lbs). Refill the coolant system. Start the engine and run at idle until it reaches working temperature. This will open the thermostat allowing the radiator to fill. Stop the engine and Recheck the coolant level. Run the vehicle for two or three days checking the coolant levels regularly.
