Car Problems tells about problems of your car of Ford Fiesta of release till 2000 with engine Zetec-SE which can arise because of failure of a drivebelt. Auxiliary units (the generator, the water pump etc.) the car of Ford Fiesta with engine Zetec-SE are resulted Poly-V-belt, in new engines OHC this problem carries out a belt 6K-Poly-V. Ford company applies basically Poly-V-belts which it is especially flexible move on radiuses of belt pulleys. The hydraulic device regulates a belt tension. Depending on a complete set of the car the air conditioner or the booster of a steering the drivebelt has other sizes, than in model with a basic set. Necessarily carry in the luggage compartment corresponding Poly-V-belt on replacement what not to have car problems.
Fig. 1. Car Problems: the Arrangement Poly-V-belt: 6K-Poly-V on pulleys of engine
Zetec-SE depending on car equipment:
1 – crankshaft pulley;
2 – pulley of the hydraulic device of a belt tension;
3 – pulley of the pump of the booster of a steering;
4 – guide roller;
5 – generator pulley;
6 – water pump pulley;
7 – an air conditioner pulley
Car problems your car of Ford can arise from a wrong tension a drive gear Poly-V-belt.Poly-V-belts should be tightened densely, but not so hardly. The deflection of a belt from 3 to 5 mm is normal by pressing the center of a branch of a belt between two pulleys. Hardly tightened belts create in due course car problems: destroy bearings of the generator, the water pump (depending on engine type) and the air conditioner compressor. Besides, hardly tightened belts are stretched and can tear further.
The weak tension also creates car problems: Poly-V-belts slip it is appreciable by creaking sounds. Most harmfully it affects the generator as thus it develops not enough charging current that leads to the big loading on the accumulator battery at trips on short distances and at start-up of the cold engine. Also it is damaged and Poly-V-belt, its lateral faces burn slightly, there is its premature deterioration. In extreme cases sliping Poly-V-belts can lead to an overheat of the engine and heavy damages of details and knots (to jamming of buckets, a burn-out of a layer pad of a head of cylinders). In spite of the fact that car Fiesta engine automatically regulates a tension Poly-V-belt, sometimes check its condition.
SEQUENCE OF WORKS
1. Check up a belt condition.
2. A hand some times turn a bent shaft. Only so you can reliably check up a condition Poly-V-belt on all its length. Often Poly-V-belts have one, but very deep crack. And if this crack, unfortunately, at visual inspection is on belt to a pulley, you it won't notice that eventually can lead to serious consequences, despite the carried out control.
3. If you have found out on Poly-V-belt following damages, at once replace it:
– Non-uniform wear tracks on belt lateral faces;
– Porous, shabby edges of a belt or a surface;
– Cracks.
PRACTICAL ADVICE
Installation Poly-V-belt.
Never put on a screw-driver a new belt pulleys. Otherwise the subsequent damages on the bottom party of a belt in places where you inserted a screw-driver will be programmed". After installation of the belt which was in the use the engine should work approximately 3 mines (if a belt new – 10 mines), then repeatedly check up a pretension. Before an engine cutoff increase rotary speed of a bent shaft a little. Approximately through 1000 km of run repeatedly check up a belt tension (the deflection should make 3–5 mm).
Installation Poly-V-belt
SEQUENCE OF WORKS
1. Turn away a fastening bolt on a tension buckle of the generator.
2. Turn away a bolt on a rotary bearing part.
3. Turn away the generator in a direction to the engine.
4. Replace old Poly-V-belt with a new belt.
5. Installation is spent to sequences, return to removal.
PRACTICAL ADVICE
If the belt has torn If during movement the indicating lamp of gymnastics of the accumulator battery of red color lights up, it specifies in breakage Poly-V-belt. Thus you will notice rigid blow on a wheel niche or a front wall in a motor compartment. In no event it is impossible to continue movement further as the water pump is put in action by a belt and coolant circulation stops, and the remained liquid in the cylinder block quickly will begin to boil, you risk to receive the hardest damages of the engine.Therefore at once replace the torn belt spare or tow off the car in the nearest auto repair shop.
