I installed a cable operated water valve for 12.00 bucks. I have a couple of servos but havent installed them yet since the cable does the trick. I even jumped the AC compressor wires and ran it to a switch. Our Nanny drive the old 77 300D and doesnt seem to mind. I guess when I have more time I'll swap the servos. Remember that when the servo goes it will burn out the Amp as well and they are around $100 bucks as well.

Great Idea. I like your thinking. Question? The heat is not going through the servo now so wouldn't that be like turning off the valve that I'd shown in the drawing. Am I wrong. I'll look closer at a necessary by pass also. Thanks retx

Could the amp you described be burnt causing it not to work. Where is this amp.

Im not sure if i follow you. Have you already bypassed your servo now? You could always just bypass the aux pump as well.

Would that cause the antifreeze not to circulate well enough or will the water pump be enough. I always wondered why there was an aux pump in the first place. RAY M

yeah, i have wondered why there was an aux pump as well. maybe someone here will let us know. do all the 617s have an aux pump or just ones with the servo? hmmmm
