There were only 2 engines available in the '89 Cavalier. If it's a 4cylinder, it's a 2.0liter If it's the V-6, then its a 2.8liter. There also should be a sticker on the radiator core support. Also the 2.8 has it stamped on the plenum chamber, top of the motor.

It depends on what engine you have as to how many you have but they are in the sides and rear of the block.
Check the heater core in the 1989 Cavalier for leaks, as this is a common place. If the core is ok, then spray the vehicle at a car wash around all windows to find the source of the leak.
