Overheating at speeds that exceed 60 mph - 2000 Hyundai Accent

1962 Ford Taunus 17 M 60 hp: The maximum speed is 135 km/h (85 mph)
1976 Ford Mustang 100 hp: The maximum speed is 173 km/h (107.5 mph)
1978 Ford Fiesta 66 hp: The maximum speed is 145 km/h (90 mph)
1978 Ford Capri 107 hp: The maximum speed is 186 km/h (115.58 mph)

Please note that these speeds are approximate and can vary based on factors such as the car's condition and modifications

possible a wheel alignment possibly from the rear wheels and loose/worn suspension rubbers

Do you have an OBDII scanner to check the real temperature? Want to make sure it's not overheating. If it's normal, could be your temperature sensor starting to go out, or ignition switch. Any check engine lights? If so, get the code for me, can go from there. At a constant speed, you sure it wasn't a misfire instead? Check your trans fluid, make sure it's full. I was just in Tahoe, pretty sad not much snow at all.

Take to a transmission shop, likely you need overhaul or replacement.

any car the rpm shouldn't exceed the 4000 round per minutes and you can check it from the sound of the car if it's so loud you should decrease the acceleration pad or give the next gear if it's manual
if it's automatic don't panic

could be sensor has failed or could be in need of tuneup...

replace fuel filtor

Instrument cluster - GM had problems with a part inside the cluster , Stepper motor , These faulty step motors caused the gauges to act erratically . 2003 to 2006 ! ALL GM vehicles . Just replaced a cavalier instrument cluster for what customer thought was a over heating problem .The fans come on low speed when engine temp. reaches 220 degress
The PCM commands the low speed cooling fans ON under the following conditions:
• Engine coolant temperature exceeds approximately 104.25°C (220°F).
• A/C refrigerant pressure exceeds 1447 kPa (210 psi).
• After the vehicle is shut OFF if the engine coolant temperature at key-off is greater than 101°C (214°F) the low speed fans will run for a minimum of 60 seconds After 60 seconds, if the coolant temperature drops below 101°C (214°F) the fans will shut OFF. The fans will automatically shut OFF after 3 min. regardless of coolant temperature.
The PCM commands the high speed fans ON under the following conditions:
• Engine coolant temperature exceeds approximately 107.2°C (225°F).
• A/C refrigerant pressure exceeds approximately 1824 kPa (265 psi).
• When certain DTCs set.
At idle and very low vehicle speeds the cooling fans are only allowed to increase in speed if required. This insures idle stability by preventing the fans from cycling between high and low speed.

Remove the dinger, this is your frendily goverment telling you to slow down. Now they can send you a speeding ticket using your own car computer and GPS.

most likely is not the engine but is a u joint in the drive shaft
