i gave it to mechanic for timing belt/water pump replacement. he called me home to inform that Aftermarket water pump leaks and have to buy new from Dealer and hence timing belt/water pump job cost me 1040/- dollars....is this true?
Water pump - After market or OEM from dealer? on 2000 Dodge Grand Caravan
There are new waterpumps available on the aftermarket however most good technicians prefer OEM quality parts. The dealer parts cost a bit more but are better quality. If he insisted on OEM parts he probably knows what he's doing.
if you trust him, go with his reccomendations. I work for an aftermarket mass marketer and wish I could get dealer parts for most repairs but we have to use our own products.
