    Hey guys, doing some new year repairs (much leaky coolant system). I'm replacing the thermostat, water pump pipe seals and replacing some hoses and I was going to reseal the thermostat to the block but noticed the connection uses metal gasket/seals.

    Is there a replacement part for these gaskets or is it just as acceptable to reuse them or replace them with cork or gasket paper?

    Not sure what you're talking about with water pump pipe seals??
    There is no gasket for thermostat, just the rubber ring on the thermostat, put the top housing on and tighten it

    I'm assuming he means where the whole thermostat housing attaches to the engine block on each bank.
    I am not sure why he needed to remove the thermostat housing in the first place, but if it is off either it was leaking, or he has already done the thermostat replacement wrong.

    Twas pretty straight forward actually. Needed a bit of fiddling getting the assembly back on the block and back onto that pipe. But shes lookin good now, no leaks noticed yet

    You don't happen to know the part numbers for the two larger diameter hoses going from the back of the thermostat housing heading towards the firewall or at least the diameter of these two hoses? I believe they are the throttle body water feed and return hoses.

    The heater core hoses? I think they are 5/8"
