Chrysler Repair: 2.7L dodge water pump replacement, crank pulley, water pump replacement


Question
I just got whacked with the news that, in order to replace the water pump on my '02 Dodge Intrepid (2.7L eng), the front of the engine needs to be torn down.   Is this correct?   How far must it be disassembled to replace the pump?   What is the flat rate hours to do such a job?   WHERE was the engineer's thought process when he/she designed such an engine that would require such an extensive repair for such a simple job?   Is there an advantage to having the water pump buried?   Is this a common problem with a 6 year old / low mileage (70K) Chrysler engine?   I'm in absolute shock at the thought of just how stupid this design is and I'm looking for a logical reason as to why I should ever buy another Dodge automobile.

Answer
You will recall that we exchanged q and a's earlier this month about your car. I am competing to be recognized as 'expert of the month' for November, and the voting ends Sunday afternoon. If you would consider giving me a vote, that would be most appreciated. Use the "Thank/rate" tab below where you will see "nomination?" and then change the 'no' to a 'yes' to give me that support. I hope things are well with you and your vehicle.

Hi Gary,
Yes, the water pump is in the front of the block and you have to remove the radiator crossmember and fan module for space. Then the accessory drive belts, crank pulley (damper), timing chain cover, timing chain, chain guides. I don't know the time/rate as I don't work in a shop. I don't know the basis for the design but assume it may have to do with assuring optimum coolant flow. I don't know if this is a common problem...you could check the annual Consumer's Reports to see the frequency of repair records for the engine.
I would note that there is a normal slow leak from the weep hole of fluid which is acceptable. Only replace the pump if there is a heavy deposit or a steady flow of fluid on the side of the engine block from the weep hole passage. If it is intermediate between these extremes and money is tight you might try a coolant system sealer like Bar's Leak, but I don't know that it will work.
Best of luck on your decision in this matter. The 2.7L engine is said to be a Mitsubishi design if that is any consolation.
