This bleeder valve can be  found on your Vanagon T25/T3 bus, when it’s powered by a WBX engine (water boxer). It connects all of your water hoses on top of your engine, and “bleeds” all air out of your water circuit… The quality of plastic from the eighties wasn’t that great and most of these valves are broken or about to be. So now we ‘re proud we can offer this part  in a superior than the original quality to keep your WBX Vanagon on the road for many years to come!
