Condition/Concern


Some customers may comment on a coolant leak.

The leak may be caused by the thermostat housing to cylinder head seal not being squarely aligned to the cylinder head.

Note that Engine RPO LUW is the 1.8 and not the 1.4

Having the same issue. Thermostat housing. If you start to smell coolant you need to get in for service. Good news is under warranty so no money out of pocket.
