Attention! Work is carried out on a cold engine.
Removing
1. Disconnect the battery from the ground.
2. Moisten the exhaust manifold nuts and bolts with penetrating fluid.
3. Remove the exhaust pipe connecting section at the rear of the cylinder head (drawing on the left - fastening of the connecting section (3.0 l), figure on the right - fastening of the connecting section (3.4 l).
4. Turn out from a collector the union of a pipe of recirculation.
5. Turn away nuts and bolts of fastening and remove collectors.
7. Carefully check the condition of the collector and fasteners.
8. Clean the split planes of the manifold and cylinder head from the remnants of the gasket material and carbon deposits. If there are signs of leakage through the gasket, then check the deformation of the split manifold plane, grind if necessary.
9. Put new gaskets on the cylinder head studs.
10. Install the manifolds, tighten the nuts in their original places.
11. Tighten the nuts in three or four steps to the specified torque. Tighten the bolts and nuts from the center to the periphery of the manifold.
Installation
12. Install the rest of the parts in the reverse order of disassembly.
13. Start the engine and check the exhaust manifold connections for leaks.
