when I start and run this 6.9 it will not leak, but as soon as I turn her off about a cup of coolent maybe a little more comes out around center pully (water pump) has anybody seen this before. thanks.

 

That is the sign of a water pump shaft seal worn out.......need a new pump. If you want the R&R istructions for the WP click on my name and email me...... the bolts must be in the correct places and some require sealant.....special torque also.....to much and you will strip the front cover plate.

Use email subject: water pump R&R
