Need Diagram of water pump on a 1998 Dodge Intrepid 2.7,

The engine was affected by an oil sludge problem and premature timing chain tensioner failure, which were fixed around 2002-2004. The oil sludge issue appears to have been caused by issues with the crankcase ventilation system, and while it affected a minority of engines, it could cause complete failure[1] In some cases, neglected maintenance aided in premature failure (missed oil changes or increased intervals between oil changes). It has also been stated the mileage recommendation of 6,000 in the normal operating conditions was possibly too long. Leaking oil pressure sensors could also aid in engine failure.[citation needed] It is also a poorly designed engine in the eyes of many mechanics, the water pump is located under the timing chain cover and in an oil bath, pump changing requires draining of the engine oil (which may now have water in it from pump failure) and removal of the timing chain cover, chain, and tensioner The engine was affected by an oil sludge problem and premature timing chain tensioner failure, which were fixed around 2002-2004.
