[s-cars] need parts - have slow coolant leak

[Jerry Scott]

Where is the best place to buy the 034121143E Hose Adapter on the back of
the engine?  This is where the head cooling hose attaches.  I probably also
should replace the temperature sensor at the back of the head, pt. no.
03591936M.  I prefer to buy OE if possible.

Thanks,

Jerry
