Chrysler Repair: 2.4L: damper removal from crankshaft, crank shaft, drive screw


Question
QUESTION: I need to replace my water pump but can't get the crank dampner to budge. Is there a special tool available for this process? Thanks
ANSWER: Hi Guy,
The manual shows a tool #1026 which is a three jaw articulated (2 pivots for each arm) puller tool with a central drive screw, and a insert tool #6827-A that is used after you remove the crankshaft bolt and you place the insert in/over the bolt hole, and then the drive screw presses on the insert instead of the bolt hole. These are probably Miller Tool Company numbers but others no doubt would substitute.
The Haynes manual also shows the same approach but calls the tool a generic 3 jaw puller without articulation (single pivot for each arm).
The arms have to fit in the three slots in the damper, not the outside of the pulley because if you did it the second way the damper and pulley could pull apart. It too speaks of a need for an insert so the center drive screw does no damage to the crank shaft bolt hole threads. So see if you can find a small three arm puller whose arms would fit into the slots and an insert that will be protective.
It suggests tapping on the end of the drive screw with a mallet once you have tightened down the drive screw on the insert so as to break loose the connection between the damper and the crankshaft.
Good luck on your job.

QUESTION: Thanks for your help, I rented a chrysler puller and it did the job (works a lot better than universal). While in process of the repair, I noted a coolant leak coming from front of engine near power steering pump area, but I cannot where it is originating. Is there anything in this location that you are aware of that would cause this (ie: freeze plugs etc.) Nothing is shown in the haynes manual.
Thanks for your help.

Answer
Hi Guy,
To tell you the truth I haven't seen that engine in person. I looked over the manuals and couldn't see any obvious source for a leak on the right side of the engine (the side toward the firewall), and the water pump and hoses are on the other side so I can't see how those could be involved. Could it be a head gasket leak that is dribbling down on that side? Maybe you would want to slightly loosen and then retorque the cylinder head bolts if it looks like that might be it. I have had good luck with this technique on several engines where a leak developed there, but the gasket wasn't actually blown.
