Drain the engine coolant into a clean container, so that the level is below the thermostat housing.
If necessary, disconnect the upper radiator hose at the water outlet.
Loosen the securing nuts, then remove the water outlet, gasket, and thermostat from the thermostat housing.
When installing the thermostat, always use a new gasket with sealer and make sure the thermostat spring is facing the inside of the engine. The water outlet housing on VG30i and VG30E engines has the letters UPR and an arrow embossed on the flange edge; they should always be pointing up. The KA24E, VG30i and VG30E engines have a jiggle valve on the thermostat which should always be facing up. Water outlet mounting screws should be tightened to 12-15 ft. Lbs. (16-21 Nm) on all engines but the KA24E, which should be tightened to 5-6 ft. Lbs. (7-8 Nm). Refill and check the coolant level.
What problem are you having with the fuel and temperature gauge? Are they inaccurate, not registering at all, sticking etc.?
