How to exhaust Odyssey antifreeze?

It depends on whether it is old or new. There is an emptying screw above the Type 02 thermostat. After loosening, antifreeze flows out to drain it.

If it is a new model, there is generally no emptying screw, so it is necessary to turn on the warm air to let the engine exhaust automatically after reaching a large cycle. It should be noted that the Odyssey is a front and rear air conditioner, and the rear air conditioner should also be turned on to vent.

I hope I can help you, and I hope to adopt it! thank you
