P0128 -- XKR Coolant Thermostat Change
#42
OK! I got the new thermostat in and she runs great! There was a screeching sound and a few puffs of smoke under the hood that had me worried for a few seconds at startup, but that went away quickly.
The coolant temperature used to hover around 195-200ºF as reported by my Torque for Android App on hot days (90ºF+). Tonight's drive was done at about 70-75º ambient temperature, and the coolant temp was shown at 205ºF. I thought this was a 183º thermostat! Where do you think the ECU is measuring the coolant temp?

Nope, haven't changed it. However, I did get this cool new bluetooth OBD2 thing and I have been graphing my engine coolant temperature for my daily commute and it doesn't appear to be anything unusual.
Scribbled out parts of the map to prevent a precision missile attack on the car. Ambient air temp was about 85ºF or so?
My commute is only 2.5 miles and about 5 minutes so I think maybe it's messing with the ECU somehow.

I would have stopped at the golf course and let the car rest for 4+ hours.

Housing has to be checked..
If your having problems with the temp warning or fans running more than you usual, you Must check your thermostat and the housing...Up until 2 weeks ago I noticed my fans running and I had purchase a Bluetooth scanning tool, and found my engine temp was getting above 230 degrees, after opening the thermostat housing my thermostat was completely broken and the main housing was cracked in the inside, see attached.. I managed to purchase the whole assembly from Gaudin and put it in this weekend...if you can rebuild a carburetor you can install this assembly. .My Xk only had 49k miles as well. My xk now never passes 198 degrees as of yet, and now runs awesome...It would seem the design is poor and if you have over 40k miles, it will eventually fail..
This is just my two cents..

XKR Thermostat Change
Do you recall if the thermostat you replaced was a 4 piece unit that needed assembly? The 4 piece unit appears to be the correct part for the XKR specifically (AJ811788) but just want to confirm before ordering.
Thanks!
