    Fixed my stang

    Easy to install works great. Be sure to clean under the manifold for any coolant that may have leaked before you install the housing.

    Thermostat Housing for my V6stang '07

    It arrive to me a day later due to increment weather... which is understandable, but it's promising that I received it brand new and not like CJ Pony or a dealer used stuff they send out. Easy to install, but disappointing I didn't beat or make the record time of an hour, lol. Roughly, an hour and a half to install. Works like a charm and Sally (aka V6stang '07) can keep her cool. Thanks a lot AM, OORAH!!!

    Great quality item arrives all pre-assembled includes new complete housing which also includes: New Thermostat, Thermostat O-Ring, Sensor O-ring, along with Bottom flange O-ring. You'll have to remove the throttle body to gain access and remove the whole assembled housing. Clean matting surface well and reattach. Note: You only need to drain 1 gallon of coolant from the bottom of radiator using the petcock drain to avoid coolant rushing out while removing your old thermostat housing, once new one is install refill using fresh Motorcraft Gold Coolant with distilled water only for a 50/50 mix. Ford Technical Services manual 2005-2010 V6 diagram for bolt torques. Thermostat Housing: 3 bolts torqued to (10 Nm, 89 inch lbs.) 5/16 socket. Thermostat Housing Cover: 3 bolts torqued to (23 Nm, 9 foot lbs.) 5/16 socket for stock bolts and 10MM for new bolts on housing cover. Throttle Body: 4 bolts (10 Nm, 89 inch lbs.) 5/16 Socket.

    Perfect fit

    The thermostat housing came complete with bottom gasket which is great. The only issue I had was that it didn't come with instructions on the torque specifications. Plastic parts break and this is very crucial information.
