1997 Ford Thunderbird Problems

What owners report

Owners of this model year most often describe coolant loss from a cracked plastic intake manifold on the 4.6L V8, usually noticed as a coolant smell, white steam or an overheating gauge. Complaints also cover front-end vibration and ball joint wear, brake work, and transmission shudder, and many of the intake manifold complaints note that an extended coverage program on that part had already expired by the time the leak appeared.

   Engine cooling

   Cracked plastic intake manifold / coolant loss

   • 39 complaints (23%)
   • median 70,600 mi at 7.6 yrs old (25 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $800 (median of 5 quotes)
   • filed 1998–2011

   Complaints describe coolant disappearing with no obvious source, a sweet antifreeze smell, white steam or smoke from under the hood, and the temperature gauge climbing. Shops and dealers typically diagnosed a crack in the composite intake manifold, and owners say the repair cost several hundred dollars or more, sometimes including replacement of fouled spark plugs. Several owners note the vehicle was outside the coverage period of an extended program on the manifold when the leak occurred, and that the replacement part was later changed to a different design. Reported from roughly 26,000 to 160,000 miles, with many between 50,000 and 90,000 miles; often noticed suddenly while driving.

   1 related service bulletin

   What to check: Check the coolant level and look for crusty residue or staining at the plastic intake manifold and thermostat housing, and ask whether the manifold has been replaced and with which design. A service bulletin in the record describes an extended coverage program for the composite intake manifold.

   “Vehicle would not hold any radiator fluid,causing the temperature gauge to rise. Tried to refill the radiator fluid, but 5 minutes later it ran out. Could not drive vehicle. Took the vehicle to my mechanic,who told me that the intake manifold was cracked and needed to be replaced. He replaced the intake manifold,so the I would be able to drive the vehicle.”

   NHTSA complaint #10110043, filed 2005-02, 120,811 miles

   “Upper intake manifold on my 1997 4.6 l Thunderbird cracked and blew all the coolant into the engine compartment. I had to pay Ford to replace the upper intake and the plugs that were fouled out. They refused any responsibility even with a formal written complaint to their home office. It is my understanding this is happening to a lot of their 4.6 l engines in a variety of vehicles.”

   Suspension

   Front-end vibration and ball joint wear

   • 14 complaints (8%)
   • median 71,568 mi at 8.8 yrs old (5 state mileage, few)
   • filed 1997–2006

   Owners describe a shimmy or shaking felt through the steering and front end at highway speeds, sometimes with a pull to one side that persists after alignment. Others report that ball joint and stabilizer bar dust seals were found cracked or deteriorated during routine service, and in a few cases a lower ball joint broke while driving, causing loss of steering control. Complaints note repeated balancing, alignment and dealer visits without a lasting fix. Mostly reported between about 50,000 and 115,000 miles, though some owners describe the vibration from early in the vehicle's life.

   What to check: Have a shop inspect the front ball joints and their dust boots, and test drive at highway speed to feel for vibration or pull. Ask for service records showing whether ball joints, tie rods or bushings have been replaced.

   “To whom it may concern! My 1997 Ford Thunderbird is not listed why? I have a lot of problems with the smog stuff every year I pay a lot of money. When temperatures are hot outside over 90 the engine light comes on and says service engine, or when I go up a long hill and my car overheats the engine light comes on and says service engine and it is always about an oxygen sensor or other smog related items that always cost $300 to $650 I am going b broke being on a fixed income. …”

   NHTSA complaint #10130641, filed 2005-07, 33,573 miles

   “While driving 40 MPH, the front lower ball joint snapped, causing the consumer to lose steering control. The consumer managed to pull over. The incident occurred without warning while in motion. The repair department suggested that the consumer should expect this at 70k miles. Ford had not responded to the consumer.”

   Brakes

   Brake wear, rotor pulsation and stiff pedal

   • 12 complaints (7%)
   • median 60,000 mi at 7.2 yrs old (1 states mileage, few)
   • filed 1997–2016

   Complaints describe frequent replacement of front pads and rotors, with a burning smell or shuddering when braking, and in one case a stiff brake pedal along with a crack found in the master cylinder. Owners report repeated brake jobs at low mileage and say the problem returned. Some complaints note the vehicle was not included in a brake-related notice covering other models. Reported at a wide range of mileages, including several brake jobs within the first 40,000 miles.

   What to check: Inspect pad and rotor thickness and look for scoring or heat discoloration, and ask how recently the front brakes were serviced. Check for a firm, consistent pedal and have the master cylinder and lines inspected if the pedal feels stiff or long.

   “While driving, the brakes got stiff. When making a turn, the tie rods snapped off. The vehicle was taken to the dealer which found a crack in the master cylinder. The master cylinder along with other parts were replaced. Please provide further details.”

   NHTSA complaint #10050106, filed 2003-12, 60,000 miles

   “They replaced the manifold and then the radiator malfunctioned, 18.000 miles later the heater core failed, was replaced in the last 6 months since aug 4 times. Ford does not have a clue and the dealer is trying to fix it each time at leaks.the brakes/rotors have been a cronic problem since the car was new. The calipers have been resurfaced 3 times and finally replaced.”

   Transmission and drivetrain

   Transmission shudder and shifter sticking in Park

   • 10 complaints (6%)
   • median 71,568 mi at 9.1 yrs old (7 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 1999–2013

   Owners of the 4.6L V8 describe a shudder or vibration during upshifts, particularly between third and fourth gear, which persisted after fluid service. Others report the floor shifter sticking in Park in cold weather, taking several minutes before it would move into gear. Complaints mention transmission or torque converter diagnosis at the dealer, and in one case the dealer could not obtain a replacement shifter part. Reported from about 27,000 to 162,000 miles, with the shifter complaint tied to cold weather.

   1 related service bulletin

   What to check: Test drive and feel for shudder or hesitation during light-throttle upshifts, and check that the shifter moves cleanly out of Park when the car is cold. Ask whether the transmission has been serviced and whether the powertrain control module has been reprogrammed.

   “I was curious about how to get the Thunderbird (1994-1997) transmission recalled? Please note that this only affects the 4.6 v8 thunderbirds and not the v6. This can result of control loss of the automobile and can result in a crash. For whatever the reason may be, my 97 Thunderbird transmission is shuttering as it shifts between 3rd and 4th gear and I have used the correct fluid and had it serviced. The mechanic said there was nothing wrong with it, however it continues to shutter. …”

   NHTSA complaint #10287146, filed 2009-10, 162,000 miles

   “Dt: the contact stated the floor shifter was sticking in park when the weather was cold. It took five to ten minutes to move the shifter into other gears. The vehicle was taken to the dealership for inspection. The dealer said the part was unavailable, and they would have to go to a junk yard to locate another shifter. No repairs have been made.”

   Fuel system

   Fuel smell and leaks from fuel lines near the tank

   Mentioned in 4 of 60 sampled complaints

   Complaints describe a gasoline smell inside or around the car, sometimes strongest at highway speed, traced to corroded fuel lines or a leak at the top of the fuel tank where a line rubs against the body. Owners report the lines being replaced entirely, one at a cost of several hundred dollars. Some owners ask whether a recall covers the condition. Mostly reported above 100,000 miles, though a few cases appear around 70,000 to 80,000 miles.

   What to check: Look and smell for fuel residue along the lines running from the tank to the engine bay and around the top of the tank, and ask whether the fuel lines have ever been replaced.

   “I smell gas when driving at high speed of 60 and above on freeway mostly. Once in a while I can smell it when driving at lower speeds of 25 -30mph. I used to think that I had spilled gas on the outside of car when it first started happening, but now a year later, I still smell gas and I do smoke in my car, but when I smell the gas, I will put the cigarette out. Is there some kind of recall on this problem, that can repair it. …”

   NHTSA complaint #10550111, filed 2013-10, 101,000 miles

   “A leaking fuel line on my 1997 Ford Thunderbird, (v6 engine), with 113000 miles on the car. I had the car towed to a Ford dealer who suggested replacing completely both fuel lines, because there seemed to be corrosion, so that was done at a cost to me of $548. As far as I know this car has never been in any accidents, although I bought the car used a few years ago. Luckily I noticed fuel leaking from the fuel line, and then had the car towed by aaa to the Ford dealer. So no fire occurred. …”

Buying note. The intake manifold coolant leak is the item most worth confirming before purchase: ask for proof it was replaced and check the coolant level and for residue around the manifold. Also budget for a front-end and brake inspection, since vibration, ball joint wear and repeated brake work are common themes in the complaints.
