Service Items


For QH Thermostats, the K suffix denotes a kit including gasket.

* - the QTH102 is listed for Aston Martin DB5/DB6, which also lists the QTH100 for 82 degree. This suggests that the 100 and 102 are the same dimensions. This is how the other thermostats have been picked - by seeing another vehicle which lists the QTH102 and at least one other.
