2011 Mercury 4.3 inboard

Hello
Does anyone have a video link to give step by step direction on changing spark plugs? It’s in a 2011 Tahoe Q5i and I can’t get to a few of them and not sure if it’s ok to pull off some of the hoses to reach them.
thank you

If unable to get to something on a motor that needs replacing, you have to remove things to get to it, or pull the motor. If you have closed cooling it would have AF so would need to drain heat exchanger prior

Thank you
I will start removing things and give it a go

start by removing the stuff in the bilge that is in your way. basically anything to port or starboard of the engine that is removable. put a pillow or blanket in there, may have to lay across the engine and work upside down

then if you need to remove engine bits to get to the spark plugs, you remove engine bits.

Kinda like the Porsche 911, had to pull the engine to get all the plugs out.
