2004 Lincoln Town Car Problems
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.
Check the battery cable ends frequently for corrosion. Corrosion can easily migrate under the cable insulation and cause numerous electrical faults and drivability issues.
Prior to jacking or lifting a vehicle with air suspension, you must turn off the suspension switch. The switch is generally located in the trunk or on the right side of the passenger foot well.
Erratic engine coolant temperature or intermittent overheating can be caused by corrosion inside the water pump. The impeller may spin on the water pump shaft or the impeller may corrode. Either condition reduces coolant circulation resulting in engine overheating.

2004 Lincoln Town Car Reviews
This car is the "Ultimate" trim, a step above the Cartier and was only made for the 2004 model year. I got this car in a private sale in July 2012 with 41,000 miles on it and literally driven by a little old lady. It is the ultimate cream puff. 24 mpg on the highway and it rides like a cloud. It has every option available on a Town Car and was in showroom condition. It rides and drives out perfectly and I've put 12,000 miles on it by December and I love this car more than any other Town Car I've ever had. It has been problem-free and I love driving it. It's identical to a 2011 and is mistaken for a brand new car all the time. I can't say enough good things about Bruce!
I have a 2004 Signature series with 125000 miles on it. I have not driven the car much in the past year, but it ran fine when i parked it a week ago now it cranks fine but no start. How does a car fail just sitting there? This car is in immaculate condition & all service is up to date. wtf is what i say.
