i have a 87 420 and while replacing the hoses, a valve that is dark orange in color snapped. the numbers on it is 4180 000140 7180. I have asked several different people and gotten as many answers. there are actually two of the same units and both have two lines coming out of them one is straight up and the other an angle. can someone tell me what they are. thnaks

If you have left/right temperature control, these would be the valves that control the heat as selected by driver & passenger.

On the intake manifold, correct? Closest to the right head? I have just replaced that same exact one on my 420, it is either for the EGR or the vacuum pump, not sure which. Threre are two of them, a red and a black, they are also different. I can get you the part number on the red one later or a good supplier should be able to get a new one off of that number.
