How to replace a thermostat on 2005 through 2009 Toyota Tacoma?

Before replacing a thermostat, it's crucial to check the coolant level, drive belt tension, and temperature gauge operation. If the engine takes too long to warm up, or if it overheats while the lower radiator hose stays cool, it indicates the thermostat is stuck open or closed. If the lower radiator hose is hot, the thermostat is functioning correctly. Overheating might also point to other issues like cylinder head leaks. Replace the faulty thermostat, disconnect the negative battery terminal, drain the cooling system, and remove the engine cover if it's a V6. Detach the thermostat housing from the engine, prepare for coolant spillage, and remove the thermostat, noting its orientation. Clean the sealing surfaces thoroughly. For a new thermostat installation, attach a new gasket (four-cylinder engines) or O-ring (V6 engines). Ensure the thermostat is correctly positioned with the jiggle pin at the top for four-cylinder models. Reinstall the thermostat housing with a new gasket for four-cylinder engines, and tighten it to the required torque. Reassemble the rest of the components in reverse order, refill the cooling system, start the engine, and check for any leaks or operational issues.
