Search for Water pump + timing belt kit :

Such as a spare part like the water pump is considered an integral part of the whole engine cooling system, because it serves to ensure the continued circulation of the coolant in the engine cooling concept. The pump is in front of the cylinder block. The system of the water pump consists of five main elements: the pump casing, the roller assembly with the bearing on which the impeller is mounted, timing pulley (pulley hub) and the labyrinth seal.

The pump spare part has a special protective coating against corrosion. The specifically designed impeller with high-quality bearing will certainly increase the life of the product. Water pumps are equipped with a gasket in order to install it on the engine and the specifically designed seals create minimal friction of all moving parts of the pump and at the same time eliminate the leakage of coolant.

The water pump casing has inlet and outlet openings; in addition to that it also has a receiving opening, designed for a heater hose. In front of the pump there is a pad, in which the pump shaft is mounted on a two-row bearing, with the impeller attached to the inner end of it. In order to avoid leakage of coolant, directly into the pump casing near the impeller hub is an additionally installed seal. Due to the fact that the water always gets in the bearings, they break down quickly. Drainage holes were made especially for the removal of moisture trapped in the casing.

If you need a water pump, you can acquire this spare part in our online store. And you will notice it`s corrosion resistance and high durability. And, of course, we have in our online shop the lowest prices for all auto parts: spring force increase controller, fuel tank, auxiliary pump or flywheel.

What you need to know about timing belt and water pump kit replacement: lifetime limits, common defects and their signs, tips and recommendations

Average lifetime of the car timing belt is 100 000 – 120 000 operational kilometers. As a rule, the water pump is replaced with the timing belt.

Common defects of the timing belt are wear out and stretching as well as mechanical damages: cracks, detachment of threads, breakage. The water pump breaks down because of jamming, mechanical damages, sealing elements wear out and corrosion.

The following signs signalize that the timing belt needs replacement: troubled engine start, noise at the area of camshaft, increased engine vibration and grey colour of exhaust gases. Water pump defects are characterized by increased consumption of cooling liquid, engine overheating, aggressive odour of antifreeze in the passenger compartment and increased noise from the side of the pump at working engine.

Diagnostics of the components lies in their examination which is recommended to be performed at a service station. In order to check condition of the timing belt, you need to remove its protective cover and then check tension and assess component condition visually. The timing belt is to be replaced if belt deflection is more than the value specified by the manufacturer, or if teeth wear out is noticeable, if there are delamination, cracks and oil marks on the belt surface. Having removed the timing belt protective cover you can visually assess defects of the water pump as well. In case if there are antifreeze stains on its body, pulley free movement and rust is noticeable, the component needs replacement.

Replacement of the timing belt, its tensioner and the water pump kit requires special knowledge and tools, that is why it is recommended to perform it at a service station. The thing is: you may need demounting of the valve cover, the alternator belt and the hydraulic power steering. After that you need to fix the camshaft pulley in a certain position following adjustment marks.

As a rule, timing belts and alternator belts have practically the same lifetime limit. That is why it is recommended to buy a V-belt kit before timing belt replacement in order to replace it if necessary.
