Here are the pictures of my last 2 failures of that plastic heater valve.

Both ones that failed are in the exact same corner of the valve when I replaced the last one I could hear a whistle like a vacuum leak from around that area,,,, I could even see steam raising.



Here is the new one that I added JB-Weld full to.


Side by side.


I have always had to guess at the proportions of Hardener to Steel Rosin on JB-Weld....
Well I have my lovely Coffee Freak Daughter to take the guess work out of it.

I used her scale that is Digital and self zeroing.
I placed a plastic coffee can lid on the scale and zero'ed it.
I used 4.0 gr of steel into the lid. I then measured the hardener to 8.0.... Got an exact 50/50 mix.
Stirred it and then placed it into a syringe, and used it to fill in the gaps of the new 2 heater valves, figured that I might as well kill 2 birds with one syringe.

Gotta love Walgreens, they will give you syringes which helps you get stuff forced in to the areas that you need it.


I am hoping that it can beef up or prevent another leak.... These are Meyle Branded made in China.

There is a replacement valve that is very similar to the OEM gated valve that lasted about 20 years or more on my Rabbit, that is easier on the control units to slide from hot to cold....

They are off a 83 or 84 944 Porsche non vacuum controlled.



Original VW gated heater valve.
