The coolant idiot light on my '86 4000CSq flashes under hard acceleration, braking, and cornering. The guage reads normal temp, the car has never overheated, the fan comes on at the proper temp, and the coolant level is fine. I figure the sender is bad. Does the idiot light have it's own sender, and if so, where is it? Frank -- Frank Sanford fsanford@pamd.cig.mot.com
