To change the thermostat on a 1997 Plymouth Breeze 2.0, a bucket should be placed under the vehicle where the hose for the thermostat is. This will catch any leaking antifreeze. Remove the hose clamp from the top radiator hose where it connects to the engine. Note how the thermostat is positioned in the hose. Remove the old thermostat and replace with a new one. Tighten the hose clamp after reconnecting it to the motor. Check antifreeze level and refill if necessary.
