Well my wifes 420 has 150k on it and the timining chain is starting to make noise. So decided to launch a preemtive strike and replace the chain befor it breaks. During tear down I noticed the water pump was leaking so I decided to change it while I was at it. Problem is I can't get two of the bolts out. One is behind the harmonic dampner, the opther is behind the ditributor.
What is the trick to removing these bolts?

Thanks in advance.
Bob
