About section
All procedures are described with the engine still in the vehicle. If the engine has been removed for overhaul, ignore the additional information that precedes each step.
Access to the engine compartment can be improved by removing the hood (see Section 11).
Engine. general description
To indicate the type of engine in the Section, instead of the working volume, the codes assigned by the manufacturer are used. A list of codes for all engines is given in Specifications.
The models described are equipped with water-cooled in-line 5-cylinder engines with a single overhead camshaft, a cast-iron cylinder block and an aluminum block head. All engines are installed longitudinally, in front of the car. The transmission is bolted to the rear of the engine.
The cylinder head carries a camshaft driven by a toothed belt, as well as intake and exhaust valves, each of which is closed by two springs. The valve stems run in guides pressed into the head of the block. The camshaft actuates the valves via hydraulic tappets. Oil is supplied to the pushers through special internal lubrication channels.
The engines are directly injected, i.e. swirl chambers are built into the piston heads.
The crankshaft rotates in six main bearings. Its axial clearance is regulated by thrust washers mounted on the main bearing No. 4. The toothed belt coming from the crankshaft, in addition to the camshaft, drives a water pump mounted on the left side of the cylinder block.
The valves are driven by camshaft cams through pushers. The high pressure fuel pump is belt driven from a sprocket on the rear of the camshaft. The vacuum pump is located on the left side of the cylinder head and is driven via a plunger by an eccentric on the camshaft.
The engine has a full flow lubrication system. Oil pump with crescent eccentric. The cartridge type oil filter is located on the right side of the cylinder block.
Repair operations performed without removing the engine
Without removing the engine, the following actions can be performed:
- a) Auxiliary drive belts - removal and installation;
- b) Camshaft - removal and installation; *
- c) Camshaft oil seal - replacement;
- d) Camshaft sprocket - removal and installation;
- e) Water pump - removal and installation (see section 2);
- f) Crankshaft seals - replacement;
- g) Crankshaft sprocket - removal and installation;
- h) Cylinder head - removal and installation; *
- i) Engine mounts - inspection and replacement;
- j) Assembly of the oil pump / mesh oil receiver - removal and installation;
- k) Pallet - removal and installation;
- l) Toothed drive belt, its sprockets and cover - removal, inspection and installation.
* Procedures for rebuilding the cylinder head and removing tappets and camshafts are given in Section 1B.
Note: Theoretically, pistons and connecting rods can be removed directly in the engine compartment (after removing the cylinder head and sump). However, it is not recommended to do this, because such procedures are much easier to perform on a removed engine (see Section 1B).
