I have a 2005 Lincoln LS Ultimate Sport 3.9L V8. Like a lot of LS owners, I am having heating issues. Last week I noticed smoke coming out of the engine. I investigated and discover that one of the hoses, coming off the thermostat then goes into the radiator then some other hose on the bottom, had a hairline crack in it and had exploded coolant all over the engine. The hose has two rubber hoses with a plastic junction in the middle with a hose that goes up the bottom. The hoses and plastic part are fused together so it's not like I can just replace the plastic part that got cracked. The part number on it says 3W43-8B274-BF. I have looked everywhere for this part and have come up with nothing on the web. This weekend I'll be taking out the coolant reservoir, radiator, and thermostat so I can finally get to the bottom of what is causing it to overheat. But I know for sure that I need I'll need a new one of those hoses. If anyone could help me out or point me in the direction of a post that I missed with the info I need that would be pretty sweet of you. If you need a picture of the part, I'll have it out tomorrow and can post it then. Thank you and much appreciated!
