Thermostat for in hose, 85 degree
QTH142
Description
Thermostat for in hose.
Higher than standard opening temperature at 85 degrees for better heater operation.
Before fitting the new thermostat, it is recommended that you drill a small hole (2 or 3mm diameter) as shown in the photo. This allows any air to bleed out, preventing a vapour lock which would prevent the thermostat opening due to lack of coolant under it.
