    Z16XE Thermostat?

    Has anyone replaced their own thermostat as my car is giving the thermostat jammed open symptoms.

    Its 90degrees in traffic, but drops off the scale below 70 durning driving.

    Heard the 8v engines need the timing belt removed to access it, but as ive just had my belt done around 500 miles ago i really dont want to do it again.

    Is the 16v easier to work at?

    bottom left of the engine as u look from the front

    top rad hose goes from rad to stat housing to engine

    remove the hose clip to pull hose off stat
    unbolt stat using 2 bolts (unscrew coolant temp sensor out of housing and transfer to new one)

    fit new stat with supplied gasket - i run a small bead of silicone (hylomar) round too

    bolt up and fit hose back on

    done!


    id recommend dropping the coolant and reverse flusing the rad and block tho too

    **some models have new coolant temp sensor included - but obv if not then youll need to transfer it over like i mentioned above**

    It's so easy, even I gave it a go (albeit on a Z18XE Vectra!).
