How hard is putting in a water pump for my 5-series on a 1-10 scale ?and how do i put it in ? details please !? i dont have a chitlon for it . ive worked a lot on this car and i do know some things about it, but not very car savy. Thank you !!
wow, first of all the car is pretty old, becareful. u may need new clips for hoses and gaskets. from 1-10 ill say 7.
You may want to pull the radiator out also for extra room to work. It will take some time but is fairly straight foreward. Be sure to get a very thin wrench to take the fan clutch off. You should be able to get one from a bicycle shop if there is one close by. Scale of 0-10 i would say a 3-4 in difficulty.
What is easy for you may be hard for others, so I would not give the job any hardship rating. But the approximate job entails doing these...descriptions from viewpoint of person standing infront and looking towards the engine... a) remove fan blade with fan clutch by turning big nut clockwise (reverse thread) b) remove fan belt, then remove pulley attached to water pump c) remove radiator fan shroud if you can to have more space to work in d) put basin underneath engine to catch coolant and detach radiator hose connected to water pump e) remove 6 bolts holding water pump and remove pump f) clean surface of engine block to remove left over sealant/gasket g) install new pump and other removed parts in reverse order h) add coolant, bleed (using bleeder screws in thermostat housing and upper radiator hose), then top-off coolant to proper level marked on expansion tank near windshield. i) ran engine or roadtest, then recheck coolant level after overnight stay or when engine cools down.
