My 92 honda accord over heats, what kind of fluid do i put in the radiator to stop it from over heating?

When i stop the odometer hand always goes up informing me that the car in getting hot. What should i do.

You should probably junk it because the cost of repairs will be more than it is worth.

You should change the thermostat and fill the radiator with coolant. If it overheats after that you might want to look at getting another water pump.
