How do you change the distributer cap on a 91 astro van?
the distributer cap is located in the back of the engine and to
get to is is relatively painless but you have to remove the engine
cover on the inside of the vehicle which is under the dash in the
middle of the vehicle which there is 2 big standard screws holding
it to the firewall and 2 clamps holding the back side to the floor
towards the seat. once you gain access to the engine compartment
from the inside of the vehicle you will see the distributor cap
right there looking at you. it is usually held on to the
distributor by 2 small Phillips screws and will tell you first hand
if the cap has not been changed in a while you might want to use a
nut driver to break them loose and re-install in just reverse.
