2006 XLR-V Cooling System including the Supercharger coolant. As far as I'm concerned, if it isn't in the Owners Manual, it doesn't have to be checked. If you lose coolant, your Display Instrument Cluster (DIC) will print out a message indicating your coolant is too low. Stop, let the engine...

XLR-V Supercharger Coolant Since the supercharger is a separate sealed system from the engine cooling system, should I understand it to be that it doesn't need to be checked or changed? If for some reason coolant is lost, is there an indication shown somewhere?

Thank you for the quick reply. After changing the thermostat and starting up the engine and letting it run for 20 minutes the Engine Hot - AC Off did not clear itself, the mechanic had to clear it with his diagnostic computer. I'm still hoping that was the cause of the issue and not the...

Engine Hot - AC Off Today is 3/7/2017. My 2006 XLR-V erroneous Engine Hot - AC Off started occurring every couple months recently. I was just having a mechanic friend of mine reset the ECU, but got tired of that. I read this thread before and today I had my thermostat replaced with a new...

Read the original thread. This is a common occurrence. My 2006 XLR-V started to happen once a year since 2007. Many say it's an engine thermostat that sticks open occasionally and the sensor gives this erroneous message because the engine doesn't warm up fast enough. They say they changed...

Thank you again for the follow up note! I've owned my 2006 XLR-V since December 2006 when I bought it as Certified Pre-Owned with only 1300 miles on it. It came with 4 years warranty and after that I bought from Cadillac another 3. It only required a few minor issues fixed on it, so I never...

Thank you for the GREAT information!

Just curious to know, Does your traction control and stability track still function fine?

I have owned my 2006 XLR-V for ten years now and only had the problem when the Florida Sun Pass transmitter was left in my unattended car for a few days. See me previous post. I have had a new cheap Walmart battery replaced every two or three years. I only put seven thousand mile a year on...

The supercharged 4.4 liter Northstar LC3 is one of the finest engines ever built. Does anyone know how many miles it will run until it is completely spent?

NO...the electronic stability control has tolerances built in to ignore the small difference. Total tread depth is only 5/8" from new to bald and does not change the outside diameter enough to screw up the electronic stability control system. I have researched in order to know this!

Goodyear makes correct size run on flat tires to fit front and rear tires of XLR-V's. They are: ***Goodyear Efficient Grip ! ~ Run On Flat Rear Tire Size 255/40R19 $291 Speed Rating = Y (186 MPH) Front Tire Size 235/45R19 $193 Speed Rating = V (149 MPH) Load Index = 100 Load Range = XL...

I had the same problem, after a few trips to the dealer they put a super-technician on it to find the problem was the Florida Sum Pass transmitter that was stored in my rear center console storage compartment wasn't letting my electrical system go completely to sleep after my engine was turned...

I've bought the car from a Cadillac dealer as a Certified Pre-Owned with only 1300 miles on it. It was never tampered with before I owned it, but I'm surprised that you say a low operating thermostat would cause an "engine hot" display????
