1. Ignition off - hold down AUTO and RECIRCULATION buttons and
switch on the ignition
2. press AUTO button - if ZERO shows, there's no stored
error codes
3. press FACE button repeatedly to scroll through stored
fault codes
4. press FACE and HEATED REAR WINDOW buttons together to
clear a fault code.
5. repeat step 4 if there's more than one code
6. press FAN button to exit Interrogation Procedure

What any codes mean can be found on Gus's JagRepair site at http://www.jagrepair.com/images/Auto...iagnostics.pdf

Codes 14 or 15 look to be possibilities.
thank you very much.

OP here again. So during a run of 45 miles I recorded the following,
From cold, 13c, a steady rise over 2 miles to 86c which held for about a mile then slowly upto a steady 94c. Slight variation depending on engine load of +2c. When stationary temp rose to 97c and fans could be heard running.
Seems to be operating as per the spec uploaded earlier in the thread.
Does seem to have a very tight temperature tolerance.

For sake of discussion, I think it is also worth noting that coolant temp. may actually increase when driven at speed if the cooling system is getting plugged up, especially the radiator core. Of course, a failing head gasket can also cause this, but less likely.

Too many to list, but include engine coolant temperature, oil temperature, fuel trim readings, etc etc. I have my X60 mounted on the dash at the left edge. It doesn’t obscure forward vision and is easily observed when desired.

There are more elegant temperature gauge solutions that take the place of the central 3 gauges, but for the bang for the buck, the X60 is hard to beat.

the stock temp gauge is just the equivalent of an on-off warning light, and won’t move off the center until the engine is well into overheating territory.

my ‘02 XKR normal temperature ranges from 185 F to 215 F depending on the outside air temperature. Even up into the 220’s F is not going to causing engine damage. My coolant temp always comes down a bit when the airflow over the radiator is helped by speeds over 75-80mph.

BTW, my usual oil temp is usually 16-20 degrees F over the coolant temperature.

I got the Autool x60 a few days ago and today it went into the trash can. It worked Ok for the 1st day and every day after it says Connection Failed. At least that's my experience.

Sorry you had a bad experience with a product I recommended.
Seems to obviously have been a defective unit.

Why not have asked for a free replacement ?

mine has been connected for about 3 years so far . My only complaint is that the secondary displays are pretty small and my eyes aren’t as sharp as they used to be. But as far as reliability goes , no complaints.

PS I know it’s aggravating to have a cheaply made electronic product fail. I suppose they are made without any consideration given to quality control, as it’s cheaper to just replace defective units than it is to have a functioning QC department.

See https://www.thejagwrangler.com/xk8--...realgauge.html if you are interested. Made in USA, proven for nearly 10 years, 1 year warranty. For coolant temperature only uses the original coolant gauge, does not need central 3-gauges. Also includes an audible alarm for rapid overheat warning.
