Removing and Fitting the VAZ-2112 Engine Receiver and Intake Manifold

We remove the receiver and the intake manifold to carry out cylinder head removal and repair work, and also during a major engine overhaul.

Removing the throttle body

  1. Using a 13 mm socket, we unscrew the two throttle body retaining nuts from the receiver. When fitting the receiver, the retaining nut tightening torque is 15–20 N·m.

If the engine is installed in the vehicle:

  1. Using a 10 mm socket, we unscrew the two receiver retaining nuts from the cylinder head cover supports.
