I'm not sure what it is called but it's located beneath the oil pressure sender. it's like a tube that goes over another turbo, i'm pretty sure coolant goes throught it. it's located at the back of the enigne

 

wow worst description ever.

 

^--LOL Maybe a picture will help...

haha yah i was planning on getting a pick up an explaination was given at the other board thank you

 

He is talking about the Heater hose coolent feed line i think, thats my best guess....

 

Yeah, the heater hose is clamped to a plastic quick-disconnect that attaches to the motor. That's under the oil filter.

If it has been on there a while it is likely that the o-rings are oil soaked and the plastic is brittle, break it off and replace it with a new one.

I buy new ones from my local parts store in the "Help" section, they are a stock part on several years of Ford Aerostar vans. I think they sell for around $9.

Thanks for that, I broke the one off my engine, and now I have a replacement engine and don't want to break that one too. Now that I know they are dirt cheap I don't care. I was even thinking of bypassing it since it doesn't look like it does much other than allow a quick disconect which it doesn't do really well either.

Thats very interesting.

 

Well, the good thing is it spaces the rubber heater hose away from the block. FC's are notorious for having oil leak on that hose and it fails - VERY common problem on the FC. Having the oil leak on the plastic is better - doesn't seem like that heater hose is anywhere near the problem on the FD as it is on the FC.

It doesn't even have to be a leak - just a little bit of oil from when you change the oil filter will weaken the hose over time.

BTW, good find on the Help! section, Jeff!

It sure is quick connect but I haven't figured out how to "quickly disconnect" it either.

I'm pretty sure there is a special tool to release it quickly, much like Ford fuel line connections.

I'm with Dale on keeping it, a little oil on that hose over time will ruin it, for $9 keep it.
