Coolant Leak From Intake Manifold on Lincoln Town Car

Problem Description and Possible Solution

The composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.

composite plastic intake manifold has crack near thermostat housing can you replace just that part or the whole housing how much
the neck cracked bc it got to hot and the neck is just plastic so have to get a new one that wasnt plastic and it works great
Thermostat housing leaking coolant. Manifold cracked in two places - front and rear of manifold. Manifold was replaced. Total bill, including labor was: $839.32
Antifreeze leak from intake manifiold. Removed parts above it and found one large crack in intake manifild that was original equipment.It came from factory made out of a hard plastic.Replace with a upgraded intake manifold(after market) with some aluminum parts to it. After all said and done the leaks have stopped and the system is working properly again.Cost of parts and labor 600.00.
Engine missing, SES came on. Turned it in @ dealership for servicing. Cracked manifold replaced, coolant evacuated from cylinders, and new plugs/plug wires.
Small coolant loss at first. Later, when engine rpm are increased, coolant blows out big time, appearing to come from the area behind the alternator up toward the fan. Drive-ability is not feasible until repaired. I'm still weighing my options, a year or more later. This makes me very disappointed and displeased with the quality of this important part, on a so called "luxury car". Come on Ford/Lincoln/whomever, you can do better than this, if nothing else, stay with the tried and true metals of years ago.
Intake manifold was broken out around the bottom side of the thermostat housing. The manifold was changed and the problem was fixed.
intake manifold leak, had to replace the part , I got a discount so it was $ 200, fixed it myself, took about 5 hours to fix !!
Car left me stranded in Gatlinburg , TN. while on vacation. Costs me $1,400.00 to fix at dealer. Ford's recall had run out.
