Hi all, hoping someone can help me out here. I have the infamous problem of coolant getting into my washer fluid reservoir and the culprit is the o rings on the heater valve. The local MB dealer can get the heater valve, but it's unclear if it comes with the o rings. Does anybody know if it does, or if the o-rings can be sourced separately?

You can buy an assortment box of 400 metric nitrile o-rings at Harbor Freight (SKU 67580) for $8. One of the sizes should fit.
