Is there any special procedure to install the coils on the spark plugs?

I decided to check the plugs for looseness due to all the posts on this topic. FYI, my L has 1500 miles, and all the plugs were tight.

I tried to "rock" the unit back and forth a little to get it to go down in there as far a possible. From the ones I could see, it looks like the plug boot seats onto the metal surface, preventing the boot from going any further.

Just push it over the plug until it clicks. Same as putting wires on plugs, not trick.

 

I always place a 'dab' of dielectric grease on the plug end of each boot. This allows the boot to slide down easier and helps keep moisture out while allowing for a good electrical connection between the plug and boot-spring-wire.

Even when the boot is all the way onto the plug, the coil pack will still be above the head by about an 1/8th to a 1/4 inch. The coil bolt will bring the coil firmly down onto the head, thereby compressing the spring-wire that's inside the boot, making a good connection.

Thanks guys.
