Dorman 902-670 water pump housing for the 2005-2010 Volkswagen Jetta 4-cylinder 2.0L and other vehicles carries coolant to and from the water pump.

- Dorman OE FIX housing upgraded to cast aluminum to prevent cracking
- Upgraded gasket material swells less on contact with oil for a longer service life
- Two outlets and a bypass hose port
- Helps maintain correct engine temperature and guard against overheating damage
