coolant temp sensor

[aladdin]

if i unplug the coolant temp sensor my fan comes on i, if i plug it back in the fan shuts off. my voltage gauge stopped working at the same time and also the coolant temp gauge...do i have a bad sensor??????

There are 2 coolant temp sensors. The one that you unplugged at the water outlet is the one for the fan. The other is on the front of the block to the right of the AC/alt bracket. It has one wire going to it. From the sound of your problem, the issue is probably in the cluster because both your volt gauge and temp gauge don't work.

nope it was the ground on the o2 sensor, i had just hooked up my a/f gauge and the instructions told me to use the ground from the sensor but that threw everything out of whack! i regrounded it to the chasis and it cured everything.
