REPLY because the increased airflow strips away residual heat from the heat exchanger (radiator). This happens faster than the engine block warms up. Result, the rad gets filled with a gelly like slurry that does not flow. So when the thermostat finally opens, the circulation attempt to flow through a plugged rad. Covering most of the rad with cardboard blocks most of the air flow, thus reducing heat removal. If you get it right, warm coolant from the engine gets to the rad fast enough to keep the anti freeze from gelling and now the heat addition from the running engine is greater than the heat removal by air flow. Then the system works as intended. _______________________________________________ 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
