How do I drain and backflush the cooling system?

1 Answer


Jimm 7/30/2011

The cooling system drain (if equipped) is usually located on the bottom side or lower point on the radiator - in the shape of a 'T' called a petcock drain. If no drain, then remove the lower radiator hose connection at the radiator to remove the old coolant.
Once drained, then you can refill with water and use a cooling system chemical flush - following the directions on the label. Be sure after the chemical flush - you 'rinse' the system with clear water, then refill the system with fresh anti-freeze and water at the recommended 50/50 mixture.

Thanks Jimm, that does answer part of the question; but I'd also like to flush the system. Info on that I've seen advises to insert a tee connection in the heater hose but, with the front-wheel design of the Grand Caravan, I'm not able to locate that hose. Any advice would be appreciated. Dave
