Volkswagen Station Wagon, Bus Service Manual – 1968-1979

You have a 1972 Bus in bay two with a fuel leak that won’t trace, and your neighbor’s Chilton says check the line at the tank – but there is a factory bulletin that tells you to inspect the steel return pipe where it passes the front crossmember. I have seen three vans towed in because somebody used a generic spec and the fuel hose rubbed through. This is the Volkswagen Station Wagon, Bus Service Manual – the same book the dealer techs used when these things were still under warranty. 492 pages of actual factory procedure, not a rewrite by a guy who never held a 10mm wrench.

Engine and Clutch – Section 5

This is where most aftermarket manuals go off the rails. Section 5 covers the complete engine removal and clutch service for the Type 2 flat-four. You get the exact step order for pulling the engine without bending the shift rod – something I have seen done wrong more times than I care to count. The manual tells you to disconnect the rear axle boots before you lower the engine cradle. Why? Because the axle will bind and tear the boot if you skip it. That level of detail is what you pay for. Also covers valve adjustment intervals and cylinder head torque sequences. If you need the numbers for the intake manifold gasket replacement, they are on page 5-14 of the PDF.

Fuel System and Fuel Injection – Sections 3 & 10

Section 3 covers the carbureted fuel system for early models – fuel pump pressure, float level adjustments, and the eccentric screw adjustment on the 34 PICT carburetor. Section 10 is devoted to the later fuel-injected models (L-Jetronic). The manual includes the complete diagnostic tree for the electronic control unit, including pin-out values at the ECU connector. I have used this to chase down a no-start on a 1978 Bus where the aftermarket wiring diagram showed a ground that did not exist. This manual shows the actual factory color codes and the correct test light method. No guessing – the manual tells you to use a 12V test light, not a multimeter, for trigger point checks. That is the difference.

Electrical System – Section 4 with Wiring Diagrams in Color

Section 4 covers the entire electrical system, and it includes full-color wiring diagrams. Not the black-and-white reduced copies you get in reprints. Real color-coded factory diagrams. The manual breaks down the fuse box layout, the turn signal relay testing, and the combination switch repair procedure. If your bus has a dead tail light and you have already checked the bulb, go straight to the ground wire on the left rear quarter panel. The manual shows you where it bolts to the body and how to clean the contact. These busses get corrosion there every time. Also includes the starter circuit diagram with the exact amperage draw values for the starter motor.

Transmission and Rear Axle – Section 6 & Automatic – Section 7

Section 6 covers the manual transmission and the reduction gearboxes used on the rear axle of the Bus. You get the bearing preload specs for the differential, the shift rod adjustment procedure, and the axle nut torque value (it matters – 250 ft-lb minimum on later models). Section 7 is a full treatment of the optional automatic transmission – the VW three-speed automatic with the torque converter. I have rebuilt two of these using this manual. The clutch pack clearance specs are in there with feeler gauge sizes. Do not try to reuse a one-way clutch that is out of spec. The manual tells you the minimum spring free length for the governor valve. This is factory engineering data, not someone’s best guess.

Why This Manual Beats Any Aftermarket Reprint

The copy you get from AutoRepairManuals is a direct scan of the original Bentley-published Volkswagen of America Service Manual. It is the same document listed on page 3 of the original – the same one that lists the companion manuals for Beetle, Fastback, and Dasher. Every page is the original factory print. The torque values, wiring colors, and diagnostic procedures were written by the engineers who designed the Type 2. I have been a master tech since 1996, and I will tell you: aftermarket manuals get the firing order right maybe 90% of the time. They get the compression test procedure wrong about 30% of the time. This manual does not get anything wrong because it came from the source. If you need the charge pressure for the L-Jetronic system, it is printed in the injection section. No room for interpretation.

FAQ – Four Questions You Are Going to Ask

Does this manual cover the 1973 model-year changes (like the larger rear brakes)?

Yes. The manual covers all model years 1968 through 1979 inclusive. Section 8 (Brakes and Wheels) includes the changeover information for the rear brake drums and cylinder sizes. The specific year cut-in is listed in the brake section preface.

Can I use this manual for a 1971 Westfalia camper conversion?

The camper body is aftermarket, but the chassis, engine, transmission, and electrical systems are the same as a standard Bus. This manual covers all those systems.

What tool list is required for the engine removal procedure?

Section 5 lists the required tools: a 19mm socket for the axle nuts, a 10mm hex bit for the transmission flange bolts, and a ratchet strap to support the engine cradle. No special engine hoist is needed – the manual shows a jack-and-board method.

Does the manual include the vacuum line routing for the 1978 fuel injection?

Yes. The vacuum schematic for the L-Jetronic system is in Section 10, with the hose diameters and routing path illustrated. It also includes the correct tightness for the manifold bolts – 18 ft-lb – so you do not strip the aluminum manifold.

Everything you need to keep that Station Wagon or Bus on the road is in these 492 pages. The wiring diagrams alone are worth the price if you have ever chased a bad ground on a ’76 Bus.
