Automatic engine start system (VW Transporter T3)

The automatic engine starter has electric and water heating. Electric heating is switched off by a thermostat in the cooling circuit when the coolant temperature is above 55°C. The basic adjustment can only be changed in cases where it is absolutely necessary.



When the system is adjusted correctly, the marks on the cover and body of the starting device match.

Removal

Disconnect the ground cable from the battery.

Disconnect the electrical wires from the automatic engine starter.

Unscrew 3 screws from the slots, remove the cover of the automatic engine start device.

Installation

When installing, ensure that the heating coil is engaged with the leash lever.

Place the cover of the automatic engine start device, tighten the 3 screws, the marks on the cover and the body must match.

Connect the electrical wires of the automatic engine starting device.

Connect the ground wire to the battery.

If the automatic engine start system switches off too early (the engine stalls during warming up), the device cover can be rotated approximately 5 mm (between the mark on the lid and the mark on the body).



Remove the air filter, unscrew the screws of the engine starter cover, turn the cover. If the device should remain on longer, turn the cover in the direction of "zu" (maximum 5 mm from the mark).

Tighten the cover screws.

Finally, check the engine start automatic system. After warming up, the air damper should be open (be in an upright position).

If the automatic engine start system should switch off earlier, turn the cover in the opposite direction (maximum 5 mm from the mark).

Checking the automatic engine start system

Remove the air filter from the carburetor.

Turn on the ignition.

Check the power supply of the automatic engine start system: disconnect the connector, turn on the control lamp between the connector and the battery platform, the control lamp should light. Otherwise, replace the starter cover. When checking, the coolant temperature should be below 55°C.

Press the gas pedal slowly once, air damper (upper valve in carburetor) must be closed.

Start the engine.

Depending on the outside temperature, the air damper should open in about 5 minutes. Otherwise, check the integrity of the bimetallic spring and the temperature switch of the automatic engine start system.
