    Iím looking for the part number or size of the o-rings for the heater core feed and return hoses that connect to the back of the engine at the coolant cross pipe? Does anyone have or know the size? Thanks.

    They are pretty well built into the plastic couplers you can get separately from VW or from a supplier with the part number. Mind as well replace them if you havenít pulled the stock ones off ever, good luck if theyíre old a big pain.

    I've installed # 212 silicone O-rings for the heater core hose connectors (instead of replacing the connectors).

    Can't speak to the longevity of using them yet, but the sizing seemed close.

    I have lots extra (25-pack) and can send a few via US mail (in an envelope) for only a couple dollars.

    Think this is what you want. The connection is actually below the crossover pipe right into the back of the block.

    Put some Vaseline on the lip of the oring when you go to install, makes it easier to seat.

    I used a #212. I don't recall the material, probably buna-n or viton. I have 2 yrs and 11k miles on them.
