What is the procedure to change out the cap and rotor on this engine. In my truck it is completely covered by the hoses and manifold/firewall. Which fittings are it Torx?

 

Hi rowekmr,

Welcome to the Chevy Forums.

Depending on which year it is, you may have distributor-less ignition. Look for the plug wires, do they all go straight up and connect to a small coil directly above each spark plug near the injection rails? What year is the vehicle?

 

Hey Thanks for the welcome. I am sorry its a 96 Chevy 3500 CC. There are no coils above the spark plug. I hope that helps.

 

The 7.4L Vortec was offered from '96 to 2000.

My truck (also a 7.4L Vortec) is also very difficult to get back there; Unfortunately, not having experience in changing the distributor on my truck, I'm unable to be of any real help. I did find this, however, which offers a 360* view of the replacement part, which may give you an idea of what you might need. Sorry I couldn't help more.

 

they are a pain in the ***, it took me a few hrs to change it on my old work track and u need to be carefull not to break the cap. actually i think it is an non wear item and not a cap at all, my friend explained it to me once but i forgot what is in there, go to the parts place and see what they give u when u ask for a cap and rotor, im pretty sure it is a fully electric dist and there are no cap and rotor, but the plugs and wires are a bitch

 

So has anyone on here actually changed the cap and rotor?
