Thanks but, it does not have elbows and the coolant does not run through the unit, like yours. Mine has dog leg pipes that run behind and around the unit.
They have an O-ring type connection, where they push into a collar, then a screw holds them in place.
And you are right, I am NOT going to tear it back down to re[lace them
At least, not unless they were leaking,but I inspected them pretty good before re-installment. Also, they are not plastic, like the elbows that you are talking about.
I can tell you though, that on 95'* and older (and probly newer), there is a 3/4 nipple, that screws into the engine and accepts a hose from water pump, that is made of plastic and these ALWAYS go bad. I have owned over a dozen of these cars and have replaced every one with a new steel nipple.
I have never "run into" those plastic elbows that you speak of yet but, I would definitely replace those as well, if I did.
