Cherokee water temp sender

Hi, My '97 4.0l I6 cherokee has started to display an erratic temp
gauge - it sits at 0 then intermittently rises to display the correct
temp. I don't have a manual for the vehicle - where is the temp
sender located and is this (or it's wiring) likely to be the fault?
All other gauges work fine and there's no check engine light on. Thanks,

It should be a purple wire on a sensor right at the back top driver's
side corner of the engine head. That sensor runs the gauge on the 4.0.

Thanks Doug and Mike. Found it (right in front of my eyes!) - all
looks fine, will WD40 it.

Keep an eye on it, it may actually be the thermostat stuck open and
it just takes along time to warm up and may never reach operating
temperature.

I am curious as to where it was on your 97. I thought they kept the
gauge one the same at the back of the head and added one up front for
the computer.

OK, I only found a sender at the front of the engine, above the water
pump, with two wires (yeelow strip and brown stripe). Cleaning this
sender connection fixed the gauge, but that could be co-incidence...

Thanks. I was under the impression the newer one still had the back
sensor. It had a purple wire going to it. That was for a direct read
gauge. Yours likely is computer generated for the gauge then.

Trouble is that the decsription of rear engine drivers side, assuming
a LHD vehicle equates to N/S on mine, which is a pig to see into as
it's the side the inlet manifold and injectors are on.

I noticed that when the gauge wasn't working properly it was doing
something - it rose to the zero on the gauge, rather than getting no
voltage at all.

No Danny you are right. I had the same problem on my 97XJ, and
cleaning the contacts did the trick.
