Coolant leak on my 85

[zerocool61]

Whats up Vetters;

I have been struck with a small problem and i hope anyone can help. I found coolant dripping out of a small heat/cold valve for the heater in the car. The valve is under the hood on the passenger side. When you move the switch from cold air to hot air inside, this valve moves a internal flap inside the coolant piping let coolant in for hot air or blocking it for cooler exterior air. My problem is that the coolant is leaking out of the screw that is holding the arm to the flap internally. Anyone knows what I need to replace? and cost?

Thanks in advance for you help.

That entire octopus looking valve goes for about 100 bucks...their is a rubber diaphragm inside that lets warm water into the heater core...most likely that is shot...by replacing this it will also be easier to cool down the cockpit as warm water will be completely shut off with a new one.
