2003 Ford Thunderbird Problems

Extended Warranty on Ford Ignition Coils

There may be an extended warranty on the ignition coils - see your  Ford Dealer for more information-Thanks John B for this information!

Coolant Leak From Intake Manifold

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 Engine Light and Engine Misfire

The valve cover gaskets may leak oil into the spark plug wells, shorting out the spark plugs, causing a misfire, and illuminating the Check Engine Light. Commonly the spark plugs and ignition coils or wires will require replacement, along with resealing the valve cover to correct this concern.
