What can cause a crossover tube housing to leak?


Asked by Dec 30, 2013 at 05:13 PM about the 2006 Lincoln LS

Question type: Maintenance & Repair

Just had the heater control valve, thermostat replaced and coolant system flushed on my '06 Lincoln LS at my local dealership.  After I brought it home and parked it overnight, I noticed a fluid puddle under the car.  When I went back to the dealership, they said I now have a leak from the crossover tube housing.  Please note, I had no prior leaks... and now they want another $600+ to fix.  I am convinced that any damage was caused by what they during the above repairs.  Any insight?

Yep, take it back to the dealer and be nice, explain what you did here. If they still insist the leak was not caused by the work they did, disturbing the crossover hose, then get firm. tell them there were no leaks prior to 'your work"... then if they still won't fix it RIGHT ask to talk to a supervisor, hold receipt for what you paid up and make demands..not throw a fit, just firmly demand satisfaction. Hopefully there will be other customers within earshot...that always puts them on the spot.

I agree with David. However your Lincoln is 8 years old. Has the cooling system ever been serviced before this? If not, and if they used a chemical cleaning type flushing agent, it may have opened up a weak spot in the cooling system. In other words the crossover tube would have probably started leaking anyhow, eventually. But by doing the flush they just "helped it along" and it's leaking now instead of later. HTH. -Jim

I'm the original owner. The cooling system has been flushed before and I have not had any prior problem.

That's good. Chances are they shouldn't give you too much of a hard time about it then. -Jim
