Thermostat caution

This bulletin applies to 2006 and later VW Passat and Touareg vehicles equipped with the 3.6L engine. When diagnosis leads to thermostat replacement, during removal, check to see if the top hat shaped section of the thermostat housing has not become dislodged and attached to the thermostat rod.

Replacement of the housing may be necessary if the piece cannot be pressed back in tightly. The photo here shows the correct installation.
