IDParts has put together a complete service kit for a thermostat replacement on 1999-2003 Mk. IV TDIs. Often times, the thermostat housing breaks upon removal of the thermostat, or a bolt gets lost or stripped. This kit solves that problem and includes everything you need to successfully replace the thermostat:
- Thermostat w/ OEM style locking tabs (makes installation MUCH MUCH easier)
- Thermostat Housing
- Thermostat Housing O-Ring Seal
- 2 Thermostat to Block Bolts
Coolant is available as an add-on below. If you properly lock in the thermostat to the housing you should lose less than a quart of coolant.
