THE TIMING BELT & WATER PUMP KIT YOU CAN SET YOUR WATCH TO


A timing belt and water pump kit by Metelli, Graf or KWP regulates the two engine transmission shafts with perfect synchronicity. It distributes the coolant for optimal circulation, ensuring correct flow at every frequency of engine rotation. For real-life precision, over 250 tests and checks are carried out on the components, including belt tensioners and idlers. Naturally, quality such as this is not achieved overnight. But then the Metelli Group has more than 50 years’ experience in the field. Long enough to know it can guarantee the complete kit for 5 years.



THE WATER PUMP. AT THE HEART OF EVERY ENGINE

Every Metelli Group water pump is tested during its assembly with a careful check of the pressfit load dimensions value. This is followed by specific tests for impellers and bearings on the test benches, assembled pump tightness test and pulley and impeller materials hardness test. Test results show that our water pump performance exceeds that of the main premium competitors, both in terms of durability and temperature management.

TENSIONERS & IDLER PULLEYS. PUT TO THE TEST. 250 TIMES

A perfect component is only made possible by continuous research and development. For over 45 years we have developed idler pulleys through constant and thorough analysis and with hundreds of design and testing hours to refine every detail. There is no shortcut to high performance. The superior quality of a tensioner is determined by the quantity and type of tests to which its components are subjected. For automatic tensioners, this includes the bearings, bushings and springs.

BELTS YOU CAN TRUST

Timing belts are simple but fundamental components – they transmit a fully synchronous movement between camshaft, injection pump, water pump and other engine units. Belts are constantly under stress during their life cycle. To ensure a longer life, their essential parts are reinforced with teeth (where a polyamide fabric protects against wear), an elastomer body, a glassfibre core and a fabric resistant to high temperatures.

5-YEAR GUARANTEE

Our new 5-year guarantee is a reflection of the confidence we have in our timing belt kits with water pumps, branded Metelli, GRAF and KWP. This confidence is gained over time – we have been manufacturing high quality spare parts for over 50 years, so there’s not much we don’t know about their reliability and durability. That’s why we now offer the best guarantee on the market, so that you too, can feel total confidence in our kits.
