While cleaning the ground points I wanted to add a bit of anti seize to the bolts on reassembly - especially in the lower engine. I know that the copper anti seize is electrically conductive (says so on mfg site), but the "grey" anti seize (http://www.permatex.com/products/aut...ubricant_a.htm ) makes no mention of electrical conductivity.

The ground strap from the bottom of the engine looks to connect to aluminum (engine side) and brass (frame side) so I am wondering if people use the "grey" (for aluminum) version with success on the ground points.

Also, I noticed that in past service, people have applied a generous amount of antiseize (grey) to the outside of the bolt and the surrounding area. Common practice?

Thanks,
Dave

 

Anti-seize is generally a poor conductor of electricity as the metal content is relatively low thus the effective contact area is minimal. Electrically conductive grease might be a better choice?

If the anti-sieze/grease is doing any conducting you haven't torqued the bolts sufficiently - you will have good direct metal to metal conduction - I wouldn't worry about it... use any type you like.

you shouldnt use the electrical grease as a anti seize thread lube. its just for electrical connections. use the anti seize on threads, it wont insulate the thread and head from the metal contact

 

...But, only on the threads, not on the shank or the head.

 

Yea, theres no neeed to coat the whole bolt in material just a light coat on threads

 

Thanks all, lite coating on the lower thread only it is then.

Thanks,

Why antiseize on these at all? I've never seen a ground that was properly torqued come loose.

 

Actually, I am concerned about the opposite...I have had many seized bolts in my car, so each time I have access to one I want to do what I can to prevent stuck bolts in the future. My "favorite" would have to be broken cam cover bolt I had to drill out

 

Got your antiseize and loctite's backwards?

 

Too early Saturday and too late Friday!






As I was sayin, great idea aaddpp
