AISIN Engine Coolant Thermostat P/N:THH-004
AISIN THH-002 thermostat for the 2003-2007 Honda Accord 2.4L and other vehicles controls when coolant flows to the radiator. This engine coolant thermostat comes as a thermostat and housing assembly.
An engine that overheats, warms up slowly or shows a jumpy temperature gauge can point to a thermostat that is stuck or sluggish. A leaking hose, a tired water pump or a bad coolant temperature sensor can be behind those symptoms too, so track down the cause before you order.
It fits the 2003-2007 Honda Accord 2.4L and the 2010-2011 Honda Element 2.4L, with a single thermostat per vehicle.
