1.9 DCI Y reg - thermostat / water pump - wh8
I have a Renault 1.9 dci Scenic Expression Y reg ? water pump has just gone ? was only replaced 9 months ago ? done 6 000 miles in that time.. They are replacing pump / timing belt under parts warranty but are telling me that the thermostat breaking would cause water pump to go. Is this correct?

Unless a piece of the thermostat broke off and damaged the pump impeller, I find this quite difficult to imagine. In normal use, thermostats are fully open, fully closed or anything in between. No state should affect the reliability of the pump.

To my simple mind anyway. :-)

Only if it failed closed,pressurized the system and blew the seals out of the pump.
