Hey all.

Can somebody tell me if I'm screwed, or will I be ok?
I was replacing the heater hose T's in my 2006 100 series and when I was taking the old ones out (replacing them with metal ones) one of the flared ends broke off in the rubber tubing. When I noticed this I, like an idiot, tried to look into the rubber tube to find the piece by tipping the rubber hose upward, thus causing the piece to fall deeper down and past the rubber tube and into the block. Im not sure which direction that particular coolant line flows. If looking at the 2 lines, its the one closer to the driver side. The piece fell through the rubber hose closer to the engine, and into the metal pipe that stick up out if the engine. The metal pipe is at the top on the engine at the very back at the rear driver side corner. I've tried sticking a clear plastic tube down there with a vacuum at the other end to try to suck it out. No luck. I may have pushed it farther down actually. My next thought was to try to flush the coolant system with a garden hose the try to push the piece out with water pressure. Also, if the coolant flow in that line goes toward the heater core, I also figure it's cheaper to replace the heater core than a blown motor so I might as well just let it get into the heater core and push my luck there. Is there a chance that this piece gets to the water pump and gets chewed into powder by the water pump and saves my butt? I really don't know what to do here. I've never done something this stupid.

If I had to venture a guess, the piece is about 1/4" square X maybe 1/16" thick. Which, generally speaking, is a pretty large piece of hard plastic for a coolant system.

Anybody have any idea of what I can do here? Any help is appreciated.
 
I think you're somewhat safe.

It might be worth getting a ~$100 inspection camera and see if you can find it. I don't think it would be possible for it to make it to the water pump as it would have to go through the radiator first. Coolant goes from the radiator to the water pump, then the engine. Your piece is in the engine. If it's not stuck and restricting flow in the engine, it'll settle to the lower rad hose, so I'm guessing.

Might be worth starting the engine for 10-20 seconds, shutting it down, then draining and removing the lower rad hose. No idea how likely it is to actually get there, though.
 
From your description....the piece will flow toward the heater core. DO NOT even think about replacing the heater core. You have no idea what hell is involved there. The piece is not big enough to cause you any problems. It can't get to the water pump....so put it out of your mind.

You would not be the first person for this happen to and far as I know....NONE have experienced any issues from it. But good of you to check.
 
If flintknapper is correct you could start it up and run it with the hose off. The water pressure should push the piece out.

Thanks for the quick responses! I ended up talking to a mechanic buddy of mine that builds drag racers. Far from the limitations of my 100....(or is it 🤔) but anyway, he pretty much told me the same thing. Not to worry about it. So, I replaced the T's, bled the coolant system, and drove it around at operating temp for a while with no issues. And the heat is working just fine. So, I'm gonna agree with everyone by not worrying about it. I appreciate the knowledge! If anything changes, I'll be sure to update this thread.
 
I did the same thing a couple of weeks ago. The wife suggested getting my shop vacuum out to try to recover the pieces, which seemed to work fine (tons of suction on the lines) but no idea for sure that the pieces came out.
