With some owners the coolant-pump is taken for granted, which is a mistake. If the pump fails, in very short order, a matter of only a few minutes, so will the engine, at the very least the head-
Gasket will fail with the possibility of a warped cylinder-head.
So, if you want to make sure the coolant-pump on your engine is all ship-shape, then this component and perhaps some of those listed below may need adding to your shopping cart:
11350MBW000
19200MBW306
11355MBW000
19200MBW316
19527MBW000
90121MV9670
90121952000
91406SL4931
19220MBW010
The coolant pump requires effective maintenance as well. Add as many parts as you wish to the same shopping cart, gaskets, seals and new fasteners for example, and still only pay the same fixed proce shipping cost.
