Was super heat switch stock on 71' A6?
I have a totally stock 71' Cheyenne Super with a 350 SB. A friend and I recently did a complete A/C overhaul which included replacing my A/C compressor. He swore that the stock compressor came with a super heat switch that had one flat blade connection. The compressor we took off didn't, which wasn't the original one, but we put the switch on the new one. I didn't think they did, but took his word for it
My question is, would my compressor have had a super heat switch when new? And if it did, what connection ran to it? I have 2 wires that were tied off when I got the truck, one I think ran to the TCS sensor in the tranny, which I can't find. And the other to the temperature switch for the TCS system on the passenger side of the block, which I can't find either. He swears that the switch I think goes to the TCS sensor goes to the super heat switch. Everything works fine, but I want everything hooked up correct as it was when stock. I guess my 1 question is 3. Would my truck have had the super heat switch, TCS sensor in the TH350, and the 2nd temperature sending switch in the passenger side head for the TCS when new? Again, everthing is stock and I would like to keep it stock. The factory service manual isn't helping much either. Anyhelp is appreciated. Thanks! |

I don't know A/C stuff... but I have never even heard of a super heat switch?
Yes, your truck should have had a TCS set up, which would include a temp sensor on the passenger side head too. |

Do you know if the TCS temperature sending unit on the passenger side would have been the identical one (same part #) as the regular one for your gauge that is on the driver side?

The TCS sending unit on the pass side head just makes continuity at a given temp probably 195 to complete TCS circuit. The temp ga. unit gives variable readings for the guage.

The TCS switch in the passenger head is a spade connector. The Temp gage sender in the drivers head is a button connector.

Re: Was super heat switch stock on 71' A6?
Would I be correct then to use a temperature sending unit for a no gauge, warning light only application? I believe that would signal at 195 degrees. That kind would have the spade connector and not the button also. I would like to put it in for originality, I just don't know what unit to use.
Can anyone help on the knowledge of the super heat switch for the compressor? Thanks for all your help. |

Re: Was super heat switch stock on 71' A6?
the guage temp light switch would n't kick on at 195.... if that was the case, the warning light would be on all the time. I think it was rated for more like 225
