Q: How do you remove the ignition coil pack on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?
A: First, reduce the fuel system pressure and detach the negative battery terminal in order to take out the ignition coil pack of V6 model. After that, remove air filter housing and separate different electric wires' connectors with their clips. Mark where the spark plug wires are situated then pull out the assembly for ignition coil pack. While reinstalling them onto the ignition coil pack, thoroughly coat inside each of its boots with silicone dielectric compound. Disconnect negative battery terminal and intake manifold cover in order to remove V8 ignition coil. Also, disconnect electrical connector from spark plug wire boot at spark plug-remove two bolts mounting the ignition coil, then remove it as well. The opposite of taking apart is how these models are put together again during installation.
