You can Select Your Vehicle to check if 1S7Z-8575-AG fits your vehicle.

To remove the thermostat, remove the drive belt, power steering bracket, tube, air conditioning compressor, cooling fan, shroud, and ignition coil cover. After that, replace the thermostat rubber seal. During installation, replace the sealing ring, fit the thermostat, and tighten the bolts. Finally, let the engine reach normal temperature and inspect for leaks.

Before you assume the problem in your cooling system is the thermostat, check other things including checking the coolant level, drive belt tension, and temperature gauge operation. You must not run your vehicle without a thermostat so that your computer can work well and it will not have any negative effects on emissions or fuel economy. Disconnect the negative battery cable to replace the thermostat. Remove air cleaner air ducts and drain cooling systems. Look for an upper or lower radiator hose to locate thermostat housing. If there are any electrical connectors present disconnect them. In some engines, both housing and thermostat are serviced as one piece. Free hose from fitting, also cut off old or deteriorated ones when necessary and replace them with new hoses if possible.

Start by checking the coolant level, drivebelt tension, and temperature gauge operation.
