Plastic junction with bleeder valve for 1.9ltr Vanagon with a manual transmission. Fits from chassis number D-089699 thru 1985. This one DOES NOT fit automatic or very early 83.5 models. However, this is a cheaper alternative to our custom aluminum version.

For Rare Early Models: Are you looking in your 1.9L engine compartment and not seeing this junction? Instead, do you have two really long hoses that go from your coolant pipes to your thermostat housing? You are not crazy. You have the setup of the very first wasserboxer design, which Volkswagen updated after around six months to include this plastic junction with a bleeder valve and four separate hoses to make it easier to service the system. We recommend upgrading your Van to include this junction, and here's a list of the items you'll need to complete the upgrade:
001377-025121073E Cooling Hose - Thermostat to Bleeder 1.9Ltr (available in Rubber or Silicone)
001373-025121062C 1.9L Right Upper Bleeder Housing Hose to Return Pipe (available in Rubber or Silicone)
001382-025121103C 1.9Ltr Thermostat Housing to Bleeder Housing (available in Rubber or Silicone)
000892-025121102ASIL 1.9L Right Lower Bleeder Housing Hose to Feed Pipe (ONLY available in Silicone, comes w/ 2 clamps)

If you are getting the three rubber hoses and one silicone hose above, you'll need 6 clamps for the rubber hoses. However, if you are going with Silicone for all four hoses, they need special clamps already supplied with every silicone hose, so there is no need to get extra.

2 x 003977-Hose Adapters (you have 1.25" coolant pipes, but the new hoses that will connect to the return and feed lines are sized at 1.5" so these hose adapters will allow the new hoses to fit on your smaller pipes)

1 ft of 002750-5/16 Coolant Hose to connect the nipple on top of the bleeder valve junction directly to the metal water pipe, plus 2 new clamps to secure the hose.
