Engine repair (Opel Vectra B)

It is most convenient to carry out work on the engine if it is installed on a special frame.

Before repairing the engine, it is necessary to remove the following:

• intake and exhaust manifolds;
• bracket for air conditioning compressor, power steering pump and alternator;
• cooling system pump;
• fuel system components;
• wiring harness and all electrical switches and sensors;
• oil filter;
• flywheel.

If it is necessary to repair only the cylinder block, crankshaft, pistons and connecting rods, it is necessary to remove the cylinder head, oil pan, oil pump and toothed drive belt or chain.

If a complete overhaul is required, the following must be removed from the engine:

• intake and exhaust manifolds;
• toothed belt drive, pulleys and tensioner mechanism (except 2.0L diesel engine);
• cylinder head;
• flywheel;
• oil pan;
• oil pump;
• chains and sprockets (2.0L diesel engine);
• pistons with connecting rods;
• crankshaft.
