I see no direct correlation between low temp. gauge readings and impending water pump failure. Don't get me wrong, Mr. Mole... It's clear our water pumps are ticking time bombs, but I have trouble seeing a causal link.

Methinks that given the high incidence of impeller failure, it behooves all of us to keep an eye on the gauge and, when in doubt, turn the heater on as a quick test of coolant circulation.

My big concern is this... If my temperature sender is flaky in the manner we're discussing, is it capable of registering higher temps consistent with WP failure and overheat? Are crank and I flying blind here? I guess I could ground the sensor wire and see if it registers full hot. Simply unplugging the sensor causes the temp. gauge to remain pegged low.
