This is my old coil. This shows it removed the the position in the engine compartment. The black stuff was sticky. I presume tar.
This is the manifold for the fan for the heater. The rubber boot at the bottom is a challenge to get it down all the way and stay there. Mine kept trying to pop up and the rubber "foot" was not even with the sheet metal which lets hot air from the muffler up into the engine compartment. Getting it to stay down and tighten the screw clamps with no room for a screwdriver and my hand is fun!.
It is clamped down and tightly in place. If I get back from my test drive and it has come up I may scream.
