Intake manifold
1. Check manifold for defects or cracks.
2. Check the capacity of the coolant and air channels. Clear channels if necessary.
3. Check the straightness of the collector interface with a square.
- Standard value within - 0.15 mm
- Permissible limit - 0.3 mm
Installation
1. First temporarily tighten the bolts at both ends of the manifold and then make sure that the mounting surfaces are tight.
Then finally tighten all bolts to the required torque.
- The tightening torque of the intake manifold bolts to the engine block is 18-25 Nm.
2. Insert cushioning elements (4 pieces) into the intake manifold holes.
