Need to know where spark plugs are on Chev Colorado 2.8L engine

Question

I can,t see them from the top or bottom of engine

Answer 1

Unless you have over 100k miles, I would'nt mess with them. But when its time to replace them, on top of your engine it has four coil modules that are bolted with a 10mm bolt. You would have to remove the air intake duct from the air cleaner box to throtle body. Remove all four coils and set aside. Use a 8" 3/8 extension and 5/8 spark plug socket to remove the plugs. I recomend putting back some a/c Delco plugs to avoid lack of power and sometimes engine misfires.

Answer 2

Follow the plug wires.
