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.

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.
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.
I thought the radiator was running hot. Had that fixed but it continue to run hot, then I found out it was was the in take manifold now it is being repaired and the cost for me is $1700.00. I am not a happy camper.
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.
