[RJ03]

I'll start by identifying my truck, I'm original owner:

2003 H2 Adv. Series, 65K miles and love it.

Looking for some help with couple things:

1). Is there a trick to remove the factory spark plug wires off the plugs or just pry them off with force? I tried taking one off to measure it, so, I can order the right ones. Wow, they really want to stay on.

2). I'm getting ready to change the coolant, thermostat and gasket. My upper and lower rad. hoses look fine. I see no areas of dry rot or wear. Should I replace them anyway since I'm flushing the system? I guess I answered my own question.

Thanks for your help,
