Quick facts
- Part: AISIN THH-004 thermostat
- Also called: engine coolant thermostat
- Fits: 2008-2012 Honda Accord 4-cylinder 2.4L and other vehicles
- Condition: New
A thermostat that sticks can show up as overheating, a slow warm-up or a temperature gauge that wanders. Before you replace it, rule out a low coolant level (check it only with the engine cool) and a leaking hose, and ask a shop to test the cooling fan, because each of those can move the gauge too.
