Ask The Expert- water proofing the engine & electrical systems.

[El Sanchimoto]

Wanted to know what the best (or most practical) way to do this was.

I saw the dirt everyday episode where they drove 'tube sock' underwater through a pond and they mentioned dielectric grease in all the connectors. Previously I would have thought you crammed a bunch in each connector and put them back together, but after some research and hearing from a guy in my club that did it wrong (had to clean out connectors and pin slots) that dielectric grease is non-conductive, it got me wondering how would/do 'the pros' do it?

Now that I have installed the Poison Spyder heat louvers, I feel it worthwhile to get this done since water now has an easy route into my engine bay, however scarce it is here in SoCal.

Thanks in advance.

I use dielectric grease in all of my connectors and have never had an issue. Most of the newer automotive connectors are pretty well sealed and should not have any issues with the relatively small amount of additional water under the hood.
