Mopping Shop and Eating Crow

Being Monday, today is all about updating what happened over the weekend.  I was able to test drive the bus,  take a run at the mountain, work on the cooling system some more and even watch a little football.

Mopping Shop
Well, as you may expect from the sub-heading here, the test drive got a little, uh.. wet.  Like my prior attempts to drive the bus, I had all the usual trappings.  Everything seems fine, and then its not.  I started him up, checking for leaks and for air bubbles in the overflow bottle.  Nada.  Then, I drove the bus down to the local 7-11 and picked up a celebratory beer.  Drove home.  By the time I got home, the engine was warmer, and the coolant started to leak.  I parked him in front of my place and like a nervous puppy, he formed a puddle underneath.  Drat.  I proceeded to mop the garage floor where he is usually parked and backed him in.  I slid a pan under the drip, went upstairs with my now-conciliatory beer and watched the Blazers beat the tar out of Denver on tv.

Timberline Shines
I awoke to an alarm on Sunday morning, triggering a day playing in the snow.  I grabbed Boo, met my brother in Hollywood and made it to Timberline Lodge by 9:30.  We figured the resort would be less crowded on StuporBowl Sunday, but there were still quite a large number of folks there.  The weather was absolutely fantastic: sunny with a slight wind.  It was cold enough to stave-off the melting but warm enough so you didn't need lots of layers.  Perfect weather.  The snow was pretty packed, but there weren't many ruts and the groomers had churned enough to keep the top fresh.  Everything except the Palmer Ice Sheet was open, though the Magic Mile trails were pretty icy (making them fast and easy to catch edges).  Alpine, Thunder, Glade and Kruser were really good runs, with plenty of open space between folks.  The terrain parks were jammed, but I avoid those anyway.  We played until around 2 when we packed off back home.

Dinner of Crow
I dropped my brother and Boo off at their respective homes and hit the parts store for an o-ring.  I'd come to the conclusion that the leak was caused by an o-ring failure, not a human error.  I got home and my legs declared they were too tired to do anymore.  So, I snapped on the game.  Boo and I stopped for a quick bite at one of our regular spots (Mandarin Palace on the corner of Allen & Scholls Ferry), and I saw the 1st quarter there.  It seemed like it was a decent enough slow-start StuporBowl.  By the time I got home with my o-ring, got my snow stuff into the laundry and the game back on, it was nearly over.  Yes, that was an amazing finish to any football game, and it being the final game of the year makes it all the more impressive.  I watched the post-game interviews and swallowed my crow.  Maybe I'll try to watch the game next year.  It sure would be nice to see a West Coast team in there, though.

More Cooling Surgery
After the game, I took my new o-ring and swapped it into the bus.  This time, I did things a little differently.  First, the o-ring is a little oversized.  The stock part is metric, but all I could find was one in imperial sizes. So, rather than 3mm thick, it is 3.1mm.  Instead of 20mm inner diameter, it is 19.6mm.  You get my point. As a result, the o-ring was snug on the temperature sensor and snug in the flange.  Once the c-clip was back in place, I couldn't wiggle the sensor at all.  I contrast that with the ability to wiggle it enough to make it leak before, and I think I've found the leak source.
Second, I captured the coolant differently.  Rather than try to drain coolant, I caught all of it at the flange during the sensor removal.  Take a clean kitchen garbage bag and push the closed end down from the flange towards the ground.  Wrap the open end around the flange and remove the c-clip.  Pull the sensor and all the coolant goes into the bag.  Put the new o-ring on the sensor, install the sensor and pour the coolant back into the overflow bottle.  In my case, the coolant bottle didn't drain during the work, so I had to start the engine to circulate the air bubbles back into the bottle.  Then, I re-filled it from the bag.  Neat!  And no mess!

I'll test drive when I have some time this week.  Like every other time, it feels like I have it fixed.  We'll see. Maybe this time I actually found and fixed the problem.  Thanks for following along.  More next time..
