A few days ago, I warmed up the Lincoln to figure out where the antifreeze was leaking out. It was the hose to the heater control valve. There was a pinhole right at the clamp, the clamp was one of those skinny cheap clamps, and I could tell it was tightened way too much. And I’m 99% sure I’m the idiot who did that!
Actually, not the heater control valve, it’s an incredibly poorly designed interlock that won’t turn the fan on inside the car till the antifreeze running through the system is hot enough. As the antifreeze heats up, that little valve works like a thermostat and starts to open. It doesn’t stop the antifreeze from circulating, it just pushes a bar as the antifreeze warms up. The bar has a little slot in it so that when it moves far enough, the bar will slide across the ends of two vacuum lines, allowing the vacuum to pass from one to the other. I would’ve done it the exact same way if I was hanging by my ankles upside down on the backside of the moon and I only had Martian parts to work with. It’s a constant source of leaking vacuum, so a couple years ago I just completely bypassed it and I just hold off flipping the fan on high till I drive a couple minutes.
I looked all around for two days for a replacement hose. I wanted the car for the Christmas holidays. Well, no new hose in the city of Atlanta, not even the big parts warehouse that’s down by the airport. The good news is, I could still order it online, but amazingly it will take over two weeks to get it. At 36 years old, it’s starting to happen more and more. I used to be able to get all the mechanical parts without issue, but God forbid you broke a window motor or something on the dashboard or such.
I did order the new hose. In the meantime, I reverted to my teenage street smarts, and I just cut about 3/4 of an inch off the end of the hose on the car, slid it up, and put a correct hose clamp on it. Worked like a charm.
Why do I suspect that the new hose will end up in the trunk of the car, for installation at a randomtime in the future…
Merry Christmas folks
