What i need to change distributer cap

If your going to work on your own vehicles, you need a basic set of wrenches and sockets, standard and metric. Then, if you need a specialty socket or a socket you don't have fine.

My automotive databases won't give the socket size. If I grab a socket from my tool box and it is too big, I grab a smaller size socket, go from there. I'll look around, see if I can find the proper size?

check to make sure as these units had a screw driver slot as well

First you need a mechanic ! then you need to turn the engine to TDC with # 1 cylinder on the compression stroke , then you need to mark all the ignition wires so you know how they go back on, a special wrench (usually 9/16) to get to the hold down bolt on the distributor .

usually there is two screws , they are spring loaded so you turn, them push them down and unclip the distrubuter, , in the old ones, new ones are different they use 4 to 6 bolts from the top,if its the old style, replace rotor and cap,Matt

they make a special socket for it and it is on the block under the distributer cap its sideways with a wire clip on it

You will need a 3/8" drive ratchet with a 5/8" spark plug socket. There is no distributor on these engines so you won't require a dist. cap. You will want to change spark plugs, ignition wires, air filter, fuel filter and pcv valve. There are no other adjustments.

most cap -- ie filter wrenches, use a 3/8 drive

ok follow the large tension leads on top of the motor depending on engine size there should be six (for 6 cylinder) they group together on the distributor cap and go to the top of the engine under the caps on the end of the leads that go to the engine will be the spark plugs you may need a special spark plug socket as they can be in hole and normal sockets will not reach, hope that helped

What size engine is it?

Hi
see my previous post "oil filters" which basically the same as this
there is a special tool for removing the oil filter "plastic cover " - (a 14 flute 76mm cap type) & this is a "must have " or the cover can be damaged 17mm spanner/socket, 6 mm allen key for the drain in filter housing along with the new filter cartrdge you should also get the 2 "o" rings as well. there is website that Robert Aitchision hs put up which gives a complete description of how to do it with pics & what is needed.
Thanks Robert
