Mine thermostat cap (cap on thermostat housing) is shot, some of the rubber gasket material is fraying off and now it is leaking all over the place. Any ideas where to get one besides a Mazda dealership...btw I have a completely circular one and in the FSM it shows one with wings on it. Is this the replacement i would get if from Mazda.

 

You can get a STANT replacement from most local auto shops.

 

Ok thats wat i was thinking, but didn't know if the sizes were similar. Thanks for the input Mahjik
