Manual or Hydraulic timing comp. Kit?

Manual or Hydraulic timing comp. Kit?
I'm having my timing belt, kit, and
water pump replaced. As I buy the
timing component kit I'm having
trouble determining if my 2001
Plymouth Neon ( 2.0 I4 GAS SOHC
Base Sedan ) supports using either
a manual or hydraulic timing
component kit. The auto store tells
me the mechanic has to take the
timing area apart first so he can
find out whether the kit needed is
manual or hydraulic, but I need to
save time, get the right info, and
get the right part before I get to
the mechanic. If it helps, I already
purchased the correct timing belt
and water pump. I just need the
correct type of timing component
kit. Help.
