When changing plug wires on a 5.7l lt1 engine do you have to take anything off the engine before replacing them or can you just change them without taking anything off

 

i dont take anything off the car.. make sure you do it from under the car not from the top it wont work out well if you try and do it from the top

 

alot easier to take some stuff off, and also be careful the new one don't get close to the PS pulley

 

Now would be a good time to change the plugs too, if you aren't already

NGK-TR55's work wonderfully.

 

i take my balancer off. it makes it much easer to get the boots on the opti and my balancer comes off pretty easy.

 

I guess if they've been on there forever. I've never had a problem getting them off the opti.

 

the passenger side can be a pain. i take off the balancer and loosen the p/s pump when replacing mine. don't really remember how easy it was with the stock, but my MSD opti is nearly impossible to reach the plug wire boots on with the balancer still on. just be careful running the wires and make sure not to pinch any of them and keep them free of the pullies and belts and manifolds/headers. zip ties are your friend!

 

I have the a/c elminator pulley i took that off and the tension pulley.

 

when i changed mine, I unbolted the power steering pump so I could run the wires in behind it...............Good Luck!!!!!
