First off, the sensor you are referring to is not called a CHT. The sensor in question is either the coolant temperature sender, which has one single pin (looks like a screw sticking off the sensor) and is responsible for the reading on your temperature gauge. Or it's the Engine coolant temperature sensor (has a 2-3 pin plug on it) and is responsible for calibrating air/fuel ratio and determines when it needs to activate the eletric cooling fan. On 94 -98 models, the gauge sender is just behind and above the water pump & thermostat housing and is sticking out the side of a small metal pipe ( has one wire with a black boot plugged into it). The temp sensor is probably less that a foot away from it to the left and is sticking off the very top of a simila metal pipe. On 99 and up models, these sensors are allmost in the same exact location, except the may be moved further to the left a little. The easy way to tell what sensor is what, the one with the single black boot/wire is the gauge sender, and it is allmost always located on the pipe with a round white cap on the very top. And there is a small notice printed on the cap about filling the cooling sytem from that pipe. That is the bleeder port. Which sensor is the one you are replacing? What does it look like?
Oh, and ....not trying to sound rude myself, but please dont type in ALL CAPS. THAT is considered yelling....and rude.
