Factory coolant temp sender gone MAD?!@
 

Often I notice that during a high-rpm WOT, for a split second, the coolant temp gauge needle drops to it's lowest reading, then goes back to it's normal self. Has this happened to anyone else out there????

Also, I saw a link somewhere on the net about calibrating the coolant gauge to read an accurate temp rather than acting as an idoit gauge. Does anyone have this link?

Thanks for the help!
