Ouch! Good luck with that. You're not doing it out in the cold, are you? I even hated working on my car in Southern California winters. Pain from busted knuckles grows exponentially with the drop in temperatures below 70 degrees...
No, of course not. I'm in our garage and after the propane heater has run for an hour, it's nearly 40 degrees! I can hardly even see my breath. Practically tropical in there.....
And I'd rather a shop did this, but I don't want to pay $500 in labor to replace a $70 sensor.
Update: after 2 hours of the heater running, it's 45..and I haven't broken any parts yet.
Oh-oh, probably shouldn't have written that...
