High flow cooling water pump for the M96 Engines until 2005. The one best solution in preventing cilinder damage.
The main problem of the big cooling system of the 996, 997 and boxster engines is high fluctuations of temperature along the cooling system.
From cold water from the radiators entering your engine, to very hot water at cilinder bank 2 (cilinders 4, 5 and 6).
Making the coolant flow faster is the best solution to even the temperatures along the whole system.
Note: A shorter serpentine belt is nescasay.
Please chose below to order with or without this belt.
The extra short belt is for the high flow pump in combination with a -27% underdriver pulley.
