hi, i'm new to supra forums and i just got my 91 supra but i't is over heating. i don't know why it's overheating. i have replace the waterpump, thermostat so i think it's the fan clutch. well this is how the car overheat. the only time it well overheat is when it's on the freeway go 70 to 80 mph. the reserve tank would be full of hot coolant and when you take off the cap there would be steam and every morning when i start the car i can hear water running behind the dashboard. anybody know what wrong with the car.
