    I need to put the water pump housing back on the motor this weekend and forgot to get the O ring. Does anyone know the size?
    Thank in advance.

    I had a recent thread on it, that showed the Ferrari part number, also the Tstat and tri flange gasket.
    I actually went to the dealer and bought them!
    $$$$$

    In my early car its actually NOT an o ring, it's a channeled edge seal that rides the flange of the T stat.
    I suppose you could use a coating of Forma gasket and reuse your old one, unless it's badly cracked or actually broken??

    34,59 x 2,62 mm. Sounds exotic, but it's a standard size. At least over here in the metric world.
    Since it's for hot coolant, it must be made from EPDM. Not the more common NBR.

    Just a quick look on the internet I come to realize that is pretty standard size across the pond... I guess will convert it and hit the local stores to try and get one. Thank you

    I forgot to mention; BigTex is talking about the thermostat gasket and thermostat cover gasket.
    I assume you meant the 0-ring between waterpump/ thermostat housing and engine block. That's what I referred to with my post above.

    Yes the O ting between the block and housing. Does it interchange with any vehicle that you know of?
