The sales page indicates it's purpose is to control the fan.

I think it ran longer than that but maybe that was it. The problem is that her normal commute to work is only 3 miles, about 8 minutes so the battery is likely 1/2 drained anyway. So you drive 8 minutes, cut the car off, then the fan runs for 6 minutes, that'll kill any battery.jimmy57 wrote:When the sensor fails you get a 6 minute (varies a bit on some models) afterrun of the engine cooling fan. Did 6 minutes of fan running kill the battery?
Well, all good hope rides with it being the connector...and cleaning it is free ad easy...so think of that as Step1! The dried "stuff in the lower tbe parts was like candle wax...wood Skiskabob Skewer worked well to push it out, and clean up the bore.cn90 wrote:Interesting! I still have the original ECT and car runs fine at 120K miles.
Question: is this a problem with the ECT itself or the Connector?
