I have a 1980 280ZX with air conditioning. The water **** is leaking and needs to be replaced. Mine has a copper lead that goes into the heater unit somewhere under the heater core. The only one I've seen for sale is the water **** without the copper "sensor" thing. SO... does anyone know what will happen if I use the the water **** without the sensor to replace mine?? What will I loose by not having the sensor?

This is what I have (see page 8)

Any help is appreciated.

Looks like you need to find the AC compatable unit. I don't know about your application, but I THINK if you use thas one, the AC compressor will run ALL the time when the heat is on. The sensor disables the AC clutch, again I THINK.

I'm not sure how it would affect the A/C compressor 'cuz the sensor only attaches to the water ****. But, maybe without the sensor it would open the water **** when the A/C is on. IDK I'll check with MSA when the wake up on the west coast. They used to sell both water cocks. Maybe someone there knows. Thanks for your input.

Seems to me it would be one way or the other.

Found what I needed at zcarscource.com. I hate these pricey sob's but, waddya do...

did you find what the sensor does?

Sensor was supposed to affect water flow til warm or some such nonsensse. If you cut it you won't know the difference. But the water **** is rebuildable.

i think. If you
