This ATR Water Pulley is suitable for the Zetec. (Ford Fiesta, Focus, Mondeo, Race)
At the high RPMs seen during enthusiastic driving or on the track the water pump pulley is spun at such a speed that it can cause fluid cavitation to occur at the pump impeller.
This can cause a number of issues;
- Decreased flow
- Excessive vibration – leading to premature seal/bearing failure
- Damage to the pump impeller blades
- Damage to pump housing
All of these lead to inefficient cooling in the water system or even engine failure.
These are available in Black, Silver and Orange.
Our ATR Pulleys are increased in size by around 20% which in turn slows the rotation of the pump to reduce the chance of cavitation.
They are also machined from 6082 T6 grade Aluminium so have less rotating mass and are better balanced than the standard steel pulley.
