Details

The thirty-plus-year-old throttle valve housings on all Vanagons are all just plain worn out. One of the main issue with the original design throttle shaft rides directly on the housing: no bearings, no snap rings, no nothing. Over time the throttle shaft bores ovalize, and the downward force of the throttle shaft assembly causes the throttle plate to come into contact with the housing, and the resulting wear creates all sorts of issues, particularly at idle and at wide open throttle.

This GoWesty-designed throttle valve housing eliminates all of these problems. The throttle housing is completely replaced with a much more stable and sturdy design made out of solid billet and CNC machined into shape. The throttle shaft is supported by sealed ball bearings and located via snap rings, which hold the shaft firmly in place and eliminate 100% of the wear problem. Each throttle position switch and throttle plate stop has been pre-adjusted in-house during assembly: no further adjustment necessary, forever!

Installation Notes

Note: This throttle valve housing is a direct replacement for all 2100cc, and 1900cc throttle valves that have 1 micro switch located underneath the housing.* This throttle valve is NOT a direct replacement for 1900cc throttle valves with the TWO micro switches on TOP of the housing, modification to the EFI wiring harness is required for that application. The Bosch Sealed 2 Pin Female Connector Kit is necessary to make this modification.

Note for Digijet (1983-85 1900cc USA Vanagons): The vacuum port on our throttle valve housing is used on all Vanagons for the fuel tank vapor control system, and for the vacuum advance side of the Digijet distributor diaphragm. Connect the vacuum advance side of the distributor diaphragm to the vacuum port on the new housing. The vacuum retard port is connected to the intake manifold vacuum. Simply "T" off of the vacuum line that runs to the fuel pressure regulator and plumb it to the vacuum retard port on the distributor diaphragm.

*This throttle valve housing is NOT compatible with the GoWesty Engine Management System (GW-EFI). It is for Digifant/Digijet fuel injection only. If you are ready to update your vehicle to a modern and reliable fuel injection system, please click the link above.

Installer beware: Changing out any one part of your EFI system that is faulty with a new or rebuilt part may cause worse running because other settings may have changed over time to compensate for the faulty part you are replacing. Following the baseline settings procedure in the Bentley manual is required after installation. Also please read our return policy related to electric and electronic items.
