The testers normally seal just like the radiator cap which seals the port to the overflow tank

I am not able to seal the water **** with this o-ring. Water droplets ozz out after 2-3 mins of idling. I am not sure what to do here. This vacuum co*k is a nightmare. I am thinking to use GE Silicon around it 😆 - but I want to try the guy recommended in the old thread in WI who fixes it. May be he has a cure. Planning to send it to him. He charges $100.

Sounds like a good idea to me. Fortunate you were able to find some one that’s willing to take it on

He has mentioned o-ring wont work and that correct flat washer will and he will pressure test it as well before shipping. Keeping my fingers crossed.

 

 

Joe heatervalves.net was a life saver. Shipped the valve back within 24-hours of getting the new seal in and water pressure tested. Ran the car idle 10 mins and all seems nice and holding.

U hose was: Dayco 86050 the exact fit with some trimming.

While we are on this topic, where do u get this black insulation that is on the vapor line coming from evaporator in the dash and going into engine through the firewall?

there is a rip in it and I was wondering to redo this before I put the dash back.

I would change that lower braided hose for something newer if it were mine.

I thought about it, it looks a bit beat up but was actually in a better shape than the other two U and elbow which I did changed.

Is there a matching replacement for it?

I would just use heater hose from a chain parts store. Isn't that what you have on the others?

That braided stuff is original to the car so the rubber you can't see is most likely getting brittle. Just a guess but "why you're there". 😁

Ok so here it is Gates 19044. It’s a longer hose that can be cut to the right fit but is a 99% match. I can throw my old ones safely 😊

Good find. I’ve found if you have a good relationship with a parts store. I have had great luck walking in with the original, find something on there hose rack that has similar bends and adjust as needed.
