#75 of 209 Lincoln LS overheating issue
Jun 21, 2011 (9:55 am)
I wanted to thank all of you for solving my overheating problem. I purchased a one owner 2000 Lincoln LS recently and the other day it overheated during initial start-up (with the air one). I changed the thermostat and all was better for the next 2 weeks then I noticed the temp slowly climbing again. I found this site a few days ago and checked my DEGAS bottle last night and after a few cycles found a small drip coming from the seam. I'm pretty sure this is where the cooling system is sucking air and caused the temp sensor to go up so quickly. I ordered a new Dorman Degas bottle last night for $62 which I plan to replace when it arrives.
Thanks again for having this Forum. You saved me a pricy dealer visit and many headaches.

Thanks for the info on the Degas bottle. I couldn't find any problems with it so have not replaced it. Do you know where the cooling fan controller is located? The fan is hydraulic, and rotates freely, at idle it operates at normal, or low speed, but does not go to a higher speed has the temperature starts to increase with increased engine RPM. But I can bring the operating temperature back to normal by just adjusting the cabin heater fan to high and desired temp to max with the engine at 2000 RPM (in park and A/C off).
I'm also experiencing a problem now with the A/C compressor clutch. After about 10 minutes of normal operation, the clutch will cycle, but not fully engage, all the while making a squealing noise.
Can the clutch be replaced without taking the compressor out?

Sounds like an air pocket obstruction. Note that the crack in the degas bottle occurs on a seam and is tough to see. I'd try a pressure test by pinching or blocking the outlet and overflow lines. Not sure where the controller is. Never had that problem but many others have and wired in an electric fan with success. Also not sure about the clutch, but my guess would be that it is all external to the compressor and can be replaced without depressurizing the system or removing it. Good luck!

I've heard of a lot of people having trouble with the hydraulic fans and many have resolved the issue by wiring in an electric one.
