Got a question on the heater control flapper valves on a -6. On mine, the driver side flapper has a solid cap over one side of the flapper valve while the passenger side flapper valve has a hole about 1.5" in diameter in the cap.
Anyone know the a reason for the one having a hole? |

I think it was 1- 1 1/4”. It was a wurth hole saw that I chucked into the drill press. Drilled the hole, blasted the piece and then powder coated. I had 5 that were pretty rusty but still usable. I hope to make a pair or 2.
I think bdstone charges ~$50 for refurbished flapper boxes. By the time you throw out the broken ones, fix the ones that can be fixed, blast and powder coat, $50+ is a good deal. |
