REPLY I had bought the pre-mix by mistake from Walmart. Didn't read the label I guess. Checked the strenght with a tester and it read Good for -30 C. Normally I mix the solution to give me - 50C protection. Cardboard is already on place. And I lined the hood and compartment with Reflectix to retain the heat from block heater better. Last year during a cold snap, I used cardboard with 100% coverage during a cold snap; then I forgot it when it warmed up to -5C and it over heated. So this year I made sure I only had something like 80% coverage of rad area. Unfortunately we attended an out of town wedding on the day the thermometer dipped to below 30 and the weather forecast said the wind chill would drop that to below -40C. We parked overnight in a place where I could not plug in the block heater. Even if it's still liquid in rad when parked; when you drive the added air movement is enough to remove any residual heat. Result - a gel like slurry . The overflow hose popped off for some reason and dumped 3 quarts on the road.At least that is what it took to refil lto normal. Oh well! It was a bright beautiful day with totally clear skies. Not a bad time and place for a mishap. Had it fixed in less than an hour. _______________________________________________ Liveaboard mailing list [email protected] To adjust your membership settings over the web http://www.liveaboardnow.org/mailman/listinfo/liveaboard To subscribe send an email to [email protected] To unsubscribe send an email to [email protected] The archives are at http://www.liveaboardnow.org/pipermail/liveaboard/ To search the archives http://www.mail-archive.com/[email protected] The Mailman Users Guide can be found here http://www.gnu.org/software/mailman/mailman-member/index.html
