Cannot for the life of me find where the #5 cylinder is located to change the coil pack.  So me - no idea but my neighbor has been a diesel mechanic all his life and asked me to find the location of the #5 cylinder ... would appreciate help.  Also - is Thais something relatively easy I hate to bust his chops and if it’s a pain I’ll just bring it to a mechanic 

what car?

Assuming it's an EZ30, sitting in the car,  the right side bank is cyl #1 at the front of the car, #3 next moving back towards the firewall, and last is number 5'

the left side is 2, 4, 6

 

 

picture above, rear passenger side plug. 

why do you think it's the coil pack?  if this wasn't properly diagnosed then it's often something else.
