    Angry 2.2 `direct' petrol - Z22YH thermostat - £129

    `55' reg Signum 2.2 petrol.
    Rang the main dealer - £129 for a thermostat, because they come with a gasket and housing attached. None on EBay as they are not yet stocking them :-(
    Anyone know if the QTH585K (Quinton Hazell ??) fits OK ?

    Default Gates Thermostat `55' reg 2.2 petrol

    Follow up - the elbow (thermostat top cover) had tried to weld itself to the lower main hose, so I took the whole lower hose out. Even then I had to use a spoon handle and some silicone spray to get the hose to release. Thermostat elbow is quite standard and a `Waxstat' was original fitment. Got a Gates TH23582G1 82 deg C stat from Partco (Unipart) in Luton - £12.50 ish retail.

    So quite why the Stealers want to charge £129 for a `unit' is beyond a joke. Do they/Vx want to drive customers away ?

    (PS - the drain plug on the coolant pump is 13 mm hex, but held in with softish Loctite type thread sealer - bit of a bu66er to get out. Only a small amount of coolant comes out if you have pulled the lower rad hose, disconnected heater matrix hose, and taken the thermostat out, so not worth the effort of removing the pump drain plug. All in all about 5 litres of coolant came out, and I think total capacity as new (dry) is supposed to be 7.2 litres but that number came from the Castrol website)
