Firewall Question

[Adam A]

Hey All,

I've got an '05 Ford Ranger and I just threw a CB radio into it. I drilled a small whole in one of the pre-existing rubber grommits under the steering wheel (to the right of the steering column, has a bunch of electrical wires running through it) and pulled the power wires and coax cable through.

It's a pretty tight seal around the new cables, but do I have to worry about anything nasty getting into the cab now (exhaust, fumes, etc.)? Is this a real concern, or just a little truck-OCD. I tried to put a silicone seal around it, but I'm not sure it is a perfect seal.

Turned off all the lights in the garage and shined a light on the engine side of the firewall. Looked to see if the light was shinning through any holes. Could not see any light in the cab.

Also, I just tried to pour some water over the seal and nothing leaked through. Does that mean it is all sealed?

It's OCD.

If your engine is in good shape, all the exhaust and other "fumes" are not released inside the engine bay.

Even if there are unexpected funny chemicals in the engine bay, it sounds like you've got an adequate seal there; likely better than some other seals through the firewall or the floor pan.

Agree with Floored and Spott both. you more than likely have other areas that will suck fumes into the cab that are much worse than your grommet and it sounds like you got it sealed pretty good. Drive it, enjoy the CB and fuhgeddaboutit...
