hi, how long does the water pump last on e65 chassi 745i (miles)
Usually car manufacturers estimate that most car parts (like a water pump) would last the warranty period and this means 40k to 50k miles. Original water pumps from dealers which are installed during car repairs are usually warrantied for 2 years. Of course this can be voided by driver abuse such as overheating the car or low coolant level.
