  • [Corsa D 2006-2014] 1.3 CDTi EcoFlex Thermostat help

    Hi, I believe my thermostat is stuck open as my car is like Antarctica whenever i'm driving and doesn't heat up for 20-30 minutes driving.

    As a complete car newbie (18 years old) what parts do I need for replacing this?

    Thanks in advance.

    Go into a good motor spares place with your reg number and tell them you need a replacement thermostat. It comes with the housing and you replace the whole unit. If I remember right they have a rubber sealing 'gasket' so check that's there.

    You'll also need fresh antifreeze. You want the red (OAT) stuff. I usually buy 5 litres at a time, you can buy it concentrated or pre-mixed (50/50 with water).

      Welcome to the Forum.

      I would also suggest that you treat yourself to a Haynes Manual - make sure that you get the one which covers your model/year.
      You can pick them up at Halfords etc., but you can sometimes find a second hand one on line.
