Not overheating, BUT.....

Last night the wife came home and pulled the car into the garage (2008 XLR-10/12K). When running at aprox 190 F it was not hot. Turned off motor and coolant started coming out of the 'plastic bottle' at the cap. I understand the 'pressure of the waterpump and the expansion when at rest', but the cap was loose. No service people nor myself have touched that cap, and now it's loose ? My fuel filler cap also 'becomes loose' after driving a few miles. Are these things normal ? I'm sure the motor is not overheating, but why would the 'coolant fill cap, or the fuel filler cap' just BECOME LOOSE ? Thanks.

That's a strange one for sure!!

I am wondering if your water pump is going out. I had that happen on my 2004 XLR. It was leaving spots on the garage floor from being too hot.

I actually waited while they put a new one in. It is fairly easy and doesn't require a lot of teardown to get to it.

Would a quick trip into the dealer show whats being recorded in the way of "fault codes" for the cooling system. Maybe a 1 hour labor charge.

Please let us know how this issue is resolved.

A week later, and no 'spots on the floor'. Drove the car (aprox) 80 miles in 6 driving days. Today the wife calls and tells me: "the low coolant light is on". This has been the coolest day here so far. Always ran below 190 degrees (F) I will purchase some 'red coolant' on Monday and try to FILL the system once again. (cold) Tail pipes look 'black' and show no signs of coolant loss. No wet spots under the car at any stops. If this 'problem' continues, I would think HEAD GASKETS, since I see no leaks and the coolant bottle cap was "loosened" by someone or some kind of pressure. Has anyone had this kind of problem ?

I would agree except that you aren't seeing any moisture coming out of the exhaust when it's idling.

Also is it hard to start???

The coolant has to be going somewhere though.

How about a pressure test to see if any leaks pop up???

Please keep us informed.

Regards

Have you looked at the underside of the car? I recently also had a low coolant message. While there was nothing on the floor, the underside of the car had mostly-evaporated coolant on it under the front of the engine. My dealer found the leak and replaced the water outlet gasket.

Thanks ! I refilled plasic bottle to stop the 'coolant light', and will now test for ANY coolant loss. Warning only came on for a minute or two just after (cold) start up. May have not filled to correct level. I will look under the car on Friday to recheck for any coolant leaks. I've had this car since March and have not had any cooling (temp) problems with it. (3100 miles of use) The summer temps got up to 119 F on some days and she ran cool even with the A/C blasting. Has 'no burnt coolant odor' since refilling. Thank you all !

IF THE COOLAND IS BEING "BURNED" You should be able to run your finger around the inside of the exhaust tips and get a sense of what is comng out besides the usual carbon deposits. The antifreeze would be somewhat greasy to the touch...

Also put a piece of plastic down to see what lands on it. I tried news paper but it gets blown around unless you do it after the car is in the garage and remove it before you start it up.

I also agree with the idea that you can look under the car and see where any leaked material is on the bottom of the motor and transmmission. The pressure test will confirm whether or not it is a hose or loose clamp that is under pressure while the engine is running that is causing the loss or not.

Please let us know how this comes out.

I put the car out on the front porch last night, to get the temps down as far as possable. It was 47 (F) last night and no coolant light this AM. I feel the coolant level is back up to the required amount. There were no coolant 'drip marks' on the garage floor. I just don't know how the cap was loosened. I'll continue to test the coolant question, along with one tire that now has an air pressure loss problem. I'm told the chrome wheel is pleeling and the air is lost in the gap between metal coatings.

350 more miles .....

No coolant leaks, nor any other coolant problems so far. Night temps are dipping into the low/mid 40's and no 'low coolant lamp' in the AM so far. I park the car under my front porch cover "25' X 25' " and it has not been rained on so far. I just don't understand how the coolant bottle cap became loose, and the original coolant level was lost. Now looking at a 'chromed factory wheel' that is losing air pressure. Discount Tire says the 'chrome is peeling and bubbling' and this is causing the air loss. "Every day is a new day".

I am assuming that the coolant cap is still tight right??
Did you mark the level that you filled the resevor up to?

Chromed Wheel Loosing Air--Not a possibility that I am aware of unless the wheel casting is very pourus. Have Discount Tire fill it up with nitrogen since the molecules are larger and see what happens.

Also the valve/TPM assembely may just have a bad "O" ring on it.

Please let us know how these issues are progressing and resolved.

Actually 'overfilled' the plastic bottle and it has shown no problems so far (almost 500 miles) The factory chrome wheels have been inspected by my local Discount Tire. One of them (that shows no signs of curb contact) is still leaking. It drops to (aprox) 20 lbs and then just remains. DT says "the chrome is peeling and causing the leak" The info panel indicates different tire pressures in the other three every day, but the "bad one" remains the same number. Now the fuel cap seems to be impossable to install into operational position. It just clicks, but does not retain. I put 15 gallons in (fill it up) every three weeks, and just now the cap starts to act up. I've had girlfriends in the past whom acted just like this car: beautifull, sexy, everything I desired, except for the minor BIPOLAR PROBLEM ! Thank you all for your help.

Gas Cap--It can be fixed by replacing it with a new one. It's not expensive and will correct the condition.

Wheel-"I'm calling BS on the chrome peeling causing the leak". Ask Discount to fill it up with nitrogen and see what happens. If that fails then I would discuss a replacement wheel with Cadillac since the casting is faulty (safety issue). Is the car still under any Cadillac Warranty???

Also there are wheels for the car on the Internet. You may be able to pick up one, two or a set fairly inexpensively.

WE'LL GET IT ALL CORRECTED!!! There are a lot of good members here.

OK, I am just back from my local GM dealer. My "overheating at idle without AC on" problem was NOT FOUND. But I had it puke fluid on my driveway that same day before taking it in. The "engine light on" was the fuel cap leaking. Even though the DIC never read 'check fuel cap'. (it has in the past) The right front wheel "shows signs of curb damage" (as my car was a demo) so no warranty. Engine coolant temps seem more stable since oil change, so I will wait out any cooling system problems. Seems to run smoother since oil change. It only went to 25%, so I think I'll just change oil at 2500 miles instead of 5K. I really love this car, and I'm just now getting comfortable with it's "personality traits". (this is why I didn't buy a BMW or MB !) I think I'll look for a new set of wheels and just drive the car as much as I can. "First the wife, then the pets, now the CAR all have me IN LINE for their needs !" HA HA!

I hope they were using Mobile 1 as they are supposed to. The 25% remaining is the correct point to do a oil service.

Gas Cap if it acts up again just get one of the new caps and all of those problems should go away.

Overheating--Yea it will be nice to just watch all of the levels and see what happens over time.

Wheel--There have been some deals on wheels on EBAY. You may be able to get a used one at a good price there. Is the damage real bad???

I ask becauseyou may be able to pay a repair fee and switch the wheels out with one of the wheel companys that do chroming. They will fill and correct the spot and charge a small amount. LA Wheel and Tire is one of the best vendors out there.

Everybody here will help in any way they can to reslove your problems.
