Well, I picked up the car about 6 weeks ago I guess and I have had to add some coolant twice now. I didn't notice anything on the ground which I know means either a very small leak or worse the motor is eating it. Have you guys had similar problems?:banghead:

The car does have the orginal warranty left but I perfer to fix things right myself if the cost isn't too high.

Thanks
Chris

I have to add a little once a year. Something is definately wrong if you are adding coolant that often.

Let us know what you find...

This bulletin is being revised to update the part information with a new part number. Please discard Corporate Bulletin Number 05-06-02-005 (Section 06 - Engine/Propulsion System).
Condition
Some customers may comment on a coolant leak. Upon investigation, the technician may find that the leaks appears to be coming from the lower radiator (http://www.alldatadiy.com/alldata/AFI~V10553628~C40138~R0~OD~N/0/108596970/110536423/110536424/110536428/34853741/100411974/34856156/34856286) tank near the lower hose outlet.
Cause
The cooling system (http://www.alldatadiy.com/alldata/AFI~V10553628~C40138~R0~OD~N/0/108596970/110536423/110536424/110536428/34853741/100411974/34856156) may experience increased internal pressures during sustained high RPMs at elevated operating temperatures. This increased pressure may cause a weakening of the core-to-tank mating surface.
Correction
Replace the radiator (http://www.alldatadiy.com/alldata/AFI~V10553628~C40138~R0~OD~N/0/108596970/110536423/110536424/110536428/34853741/100411974/34856156/34856286) with a redesigned radiator, P/N 19129908.

Is this a "normal problem" or are they more wide spread? It pretty cold here now in Chicago and I need to get under the car and look at it some more. Thanks for the info. I will make a appt at the dealer if it looks like its coming from the tank.

I added about a pint, only once in 3.25 years, 34,XXX miles, so it is not normal. Once you confirm no tank or line leaks, go get your free radiator.
Go to Reed's FAQ site, http://www.cadillacfaq.com/faq/tsb/index.php to what else you need to get done.

Oh and by the way, the 'Fins kick the Bears arse, and for that matter every other team in the NFL-JMWY.

Some have required new radiators under this TSB even though they reported that they had not operated at sustained high rpm's or under extreme heat. Also, others have reported that the leak is almost undetectable because it is often small and only occurs while the engine is running. In fact, some folks discovered it based on an odor of coolant when exiting the car. It seems as though the coolant that leaks often evaporates rather than dripping underneath the car.

Yep.. all of the above was my situation. You won't see anything by just looking underneath unless you remove the shrouding to expose the bottom of the radiator.

Jack car up a few inches.
Secure with jack stands.
Remove shroud.
Get flashlight at NIGHT and look around from underneath.
Chances are you will find small leak running down something.

I had the exact same problem. Bought the car, added coolant a couple times, checked the forum, went back to dealer. They just changed the radiator. No questions asked, they know its a problem.

My 1st Problem was a Power Steering Pump Seal.. Then my radiator had to be replaced soon after that. After those 2 things were changed. I have not had any problems since. Knock on wood.

Thanks for the help guys. I did look last night while removing my front plate bracket and I really didn't see anything. I am going to call the dealer and make an appointment. Thanks again.
