Had a small coolant leak that I thought was the water pump. I had already replaced it at about 80,000 miles. Then a 2nd leak developed and I replaced the radiator, still had the first leak. Found the leak at the plastic elbows that connect the tensioner to the engine. I replaced them with Dorman aluminum elbows (part # 47065 HP). The plastic elbows that I removed were brittle. I did this myself, cost 15.00. Time needed, about 1 hour.
Leaking coolant from right front end of car
I purchased a Buick Lucerne 2007 from Southern Chevrolet Cadillac, Inc. Less than six months ago. I also purchased the extended warranty for the vehicle less than 48 hrs. Later the vehicle started running hot and overheating I contacted the Southern Chevrolet Cadillac, Inc. And they arranged for a tow truck to bring the vehicle back to their location for repairs from a GMC dealership 40 miles from theirs.
I was informed the clamp for the radiator had slipped lose and that was the reasons for the overheating. The vehicle was repaired and returned at no costs because it was covered under the extended warranty. This past weekend (July 20-21) the vehicle started running hot again and stopped on me about 70 miles from my home. I contacted OnStar and they ran a remote diagnosis and told me my transmission had gone out. The vehicle was towed to Southern Chevrolet Cadillac, Inc. On Monday (July 22, 2013), I was told by Karen in the service department my warranty needs to be verified.
After it was verified the next day (7-23-13) Karen told me the warranty was verified and the service department found the problem was the radiator and an adjustor need to examine the vehicle before any repairs could be done. Today (7-24-13) Karen called me and stated the warranty did not cover the radiator, and because it does not cover the radiator the damages to the motor and transmission cannot be repaired due to the radiator being the cause of the breakdown. I told her that the vehicle broke down less than a week of purchase due to the radiator and it was repaired. I was under the impression each time a vehicle is worked on the Vin number must be enter to note the repairs. Well today I was told no record showed any repairs.
I informed Karen that I missed work on Monday, had to pay for a ride today (7-23-13) and this is causing me a hardship. I asked her if Southern Chevrolet Cadillac, Inc. would provide me a loaner vehicle while the repairs process is being conducted, she stated no. The adjustor must examine the vehicle first and that normally takes 24-48 hours.
I tried to explain my having to pay someone to take to work, and that I have a new born baby and not having a vehicle is really difficult at this time, she seem dis-interested, and slightly agitated. My concerns are being stranded, not receiving any compassion from the representative (Karen). I love the vehicle! When operating properly it is awesome car, but the breakdowns have not been my fault, and may be factory concerns please review the car facts. When I purchased the vehicle I was told an extended warranty would cover this type of repairs! I just want my car fixed, and to be provided transportation while the vehicle is being repaired.
Please look into this matter for me!
Answer below is from National Auto Care, extended warranty:
Based on what the repair facility called in and stated that the radiator failed and caused the damage to the trans and the cylinder heads. The contract that you currently have on your vehicle is a power-train and will only participate in items internal lubricated of the engine transmission, transfer unit and drive assembly. On all contracts there are exclusions and why the claim was denied is that the radiator is a non listed item on the contract and per the contract exclusion #14 Damage to a covered part by a non-covered part. Damage to a non-covered part by a covered part is also excluded. In your case the radiator caused the damage.
Per your statement there was a repair done on the vehicle prior, NAC has no record that any claim was called in prior to this claim.
As pertaining to the rental NAC will not authorize rental unless we participate in the claim and unfortunately we are not participating as the reasons stated above.
If you have any further concerns and or questions please contact NAC @800-526-8678 prompt #3.

The coolant overflow tank had a crack in it, was empty, and stayed empty upon purchase of the vehicle up until another 20,000 miles past when the water pump locked up. As the water pump locked up the serpentine belt was thrown off. This occurred on a highway in a dark area at sunset. Therefore the lack of light and sufficient tools needed to allow the the radiator to drained properly were not available, thus producing an air bubble within the cooling system when adding the water and antifreeze back into the system via the radiator cap.. This is when the problems began. shortly thereafter signs and symptoms of the car running hot especially in times of Idol traffic and stop and go, it was more prone to run excessively hot. Water and anti freeze added. This would provide varying times of relief from days up to weeks. Finally the problem kept occurring even on a daily basis even when going at high-speeds where airflow was sufficient. Problem: bubble in radiator line with a burnt out thermostat. Solution:replace thermostat drain radiator, added water and antifreeze with a pressure tester to avoid air bubbles. Only problem was this was a long-term temporary solution with intermittent periods of having to add water and antifreeze to the radiator once again especially during times of increased ideling and stop n go traffic. Finally found a mechanic who solved the problem by providing his knowledge to me regarding this vehicle & how its intake system works with the cooling system and the reason why it is imperative to replace the cracked cooling tank in order to stop & avoid future problems. Apparently with this type of Buick each time you crank the car the cooling holding tank sucks air in the line and puts it directly into the mix of the radiator fluid's when the tank is empty therefore creating more bubbles in your system then a shaken soda.
2nd time had problem, 1st time replaced head gasket.this time plastic resovoir was empty.even when under pressure could't figure where leak was coming from.told to keep eye on plastic container.did't show on dash that fluid was low. no charge but very frustrated ,as we are going to florida at end of month...
In for routine oil change/maintenance. Found leaking from water pump of pink fluid. Asked if I had seen any similar leaks in garage. None noticed. Suggested replacing water pump and flushing cooling system. Done at cost of $936.02 that included replacing 2 motor mounts as well!
Crack Radiator (plastic on the top is crack). Bad cam shaft sensor which cause the car to turn off. Water pump leaking!
Keeps over heating. Was told while having an oil change that the water pump is leaking. Was told service warranty is expired. Not fixed yet. What damage will it do to my car if I drive it and just keep an eye on water reservoir.It still has water in it.
I just put on the 3rd... yes the 3rd water pump. 1st 2 times a mechanic where the part was covered But not the labor. This time I did it myself. Power steering pump wad in the way... Really??? Thanks to you tube I got it. Hope 3rd time is a charm...
