30-year old leaves on the heater core |

nasty looking valve |
A new shiny valve that I tore apart for parts. Nissan Part Number 27017-B5000. It's from a 620 pickup 70's era I think. |
You bend the brass flanges up and you can pull the innards out |
what the overnight vinegar bath did for the old valve assembly...clean huh? |
|
and another view |
holding my breath bending the brass flanges on the old valve |
Whew! They didn't break! |
Old valve guts |
and a bit of stop leak perhaps...it came out with the old valve |
Pretty dusty squirrel fan and crumbly foam |
gently pull on the heater core |
and a little more |
and it's out! |

cleaning the squirrel fan... |

Under the dash the connections were disconnected and the cables were bent. I fixed 'em all up while I was there. |
A dusty, dirty mess inside... |
The foam just disentegrated when I touched it. |

more rust and dirt inside |
A soapy bath for everything |

It's hard to see but I've fitted up black foam into the door and I'm ready to glue it in place. |
