hi
i have a 91 d 50 2.4 and the metal tube is leaking that take coolant down the side and around back of the motor to the heater core.
I believe there must be a o ring where the tube slides in.
I have not taken it apart yet, hoping to have all parts needed before taking it apart.
it appears that one bolt and the tube will slide to the rear and access will be gained to the oring( i assume ).
the parts store is no help, and they want to try and match one up after i get it apart, assuming it is in one piece.

I am hoping that someone can give me a part number, and verify my guess about the oring. I never have had any luck trying to match up orings, it seems if i get the id correct then the od is wrong.
so i am hoping to avoid the multiple trip game to the parts store.
please help
thanks
