Ok I am in need of some desperate help asap as the ls in broke down. I have searched some of the forums and I know all about the issues with degas bottle cracks and other leaks. This is what has happened. About six months ago car wanted to overheat one night while idling while I was waiting for it to warm up because it was like 30 degrees out. I checked it out and found that the degas bottle was empty. Now let me say that I had rarely checked it in the couple years I have had the ls. So I filled it back up never went through the bleed process. It done fine for six months (@ 15,000 miles) and then one day going down the road about 45 mph it done it again. Pulled over and checked degas bottle and it was empty again. Let it cool and filled it back up, now mind you it only took like 1-2 quarts to fill it so it was barely out of the degas bottle. Concerned about a leak I checked the manual and found that you should check the degas bottle monthly and care it in for service if it takes more than 1 quart to keep it topped off monthly. Well obviously it is not taking that much I just need to check it more often that previous and keep it topped off. So this time after it being topped off, I done the bleeding procedure. Ok it done fine for 3 or 4 days and then run hot again. This time the degas bottle was still full. So I tried to bleed the system again. Checked for leaks and of course didn't find any considering the bottle was still full. While I was bleeding the system I thought about the hydraulic fan. So this is what I done. I cut the car off and took a screwdriver and held one of the fan blades and started the car up so the fan would not be free spinning with the car idling with air conditioner off. Then while holding the fan still I got someone to cut the a/c on wide open and was still able to hold the fan. Should there have been enough pressure while holding the fan and turning the a/c on to of not been able to hold the fan and it force the scredriver to slide off so it could turn. Also on the instructions for bleeding the system (step #6 says to replace the degas bottle cap on all engines) so do you have the degas bottle cap on during engine idle with heater to max while bleeding the heater air bleed or does it matter if the cap is off. The reason being is it also mentions to keep the degas bottle full during this procedure but I am not sure it you leave the cap off the whole time of just when topping it back off or does it really matter wether it is off or not. I know this is a long post but I tried to explain everything I have found so fair and I need help asap as my wife is relying on the ls to get back and forth to school.
Thank you for any help. Also if somone knows a sort of troubleshooting step procedure to find out what it could be that would be great also.
