I would like to change-out the spark plugs on my 2002 Eurovan, VR6, 4-valve. I managed to tilt the radiator forward to provide clearance for long socket extension. My problem is that I can't figure out how to disengage the cable bundles from the coils, and I don't want to force anything. I presume I have to depress something, or pry something. But none of the little tabs seem to deflect when I press on them. Can you instruct me?

Also, I can't see what holds the coils in place. How do I extract them from the head?

How much should I donate for your help?
