How is that valve removed from under the cowling. My plan is to pull the gas tank for better access first; then replace the driver side heat/defrost valve. The re-install the control cables.
Any tips will be appreciated… ( see sample photo, not my car ) Attached image(s) |

Beyond the loosening of the two bolts that hold the cowl down, you may also want to remove the four nuts under the cowl that hold the dash on. Then inside the car there are two screws in the area by the door (believe knee pad has to come out to access those) to the sides of the vents (assuming a post ‘72 built car). One other bolt under the dash around the heat/vent controls and the whole dash could be moved quite a bit.
Once the dash is moved upwards (or removed completely) it’s amazing how much space there is in that area. It allows you to tilt that mix valve up without the defrost vent hitting the dash or the bottom part of the valve getting caught in the hole in the firewall. |
