What is the general community knowledge on using dielectric grease when replacing the spark plugs on and ECOTEC 2.4 or any ecotec for that matter. Yes or No?

Should it be applied to the end of the boot/coil before installing the new plugs.

Thanks

 

As in, using it as an anti-seize compound?

 

As is pertains to should it be applied to the boot/coil when installing NEW plugs.

Thanks

 

Use sparingly. It is non-conductive and the purpose is to prevent corrosion of mated contacts. IMO it won't hurt anything, but I can't speak to what GM might say about it. I've used it on my motorcycles to good effect, but the plug wires are right out in the open.

 

Also keeps the boots from glueing themselves to the plugs....Im sure a few people here have seperated wire from boots while trying to remove plug wires that hae been untouched for a few years....

 

I used to use it to make the bootsd easier to remove, until my Trans Am kept having a plug wire come off. The grease was sealing the boot on so well when the heat from the exhaust manifold expanded the little bit of trapped air in the boot, it would actually blow the boot and wire off the spark plug. It did it 3 times, until I cleaned the grease off the boot and plug, Viola, no more issues. So now I do not use the grease. Seems like on most newer cars the hard part getting the boot off is actually the firmness of the cap gripping the top of the spark plug, and not as much the boot.
