Plugging holes in firewall (1 Viewer)

[Torque]

I have quite a few small holes in the firewall from bolts that have been removed. Because of them, a lot of heat from the engine makes its way into the FJ40.

Instead of using silicone to fill the holes, does anyone know of rubber plugs or something similar that I can purchase? Or, is silicone filler the best way to go?

Can you just put the bolts back in?

Can you just put the bolts back in?

That is what I do with my vehicles and what I do when customer trucks come in the shop...

grommets have holes in them, he's trying to plug the holes. NAPA carries rubber plugs but you need to measure the hole diameter(s). They're also in packages of a given size (at least at my local store) and are bit pricey.

Grainger will only sell to you if you have a tax id #. Put the bolts back in - done.

x2. Then you'll always have a source of spare bolts for those times when some idiot is working on the car late at night and I (I mean they) happen to lose the one bolt you need to put everything back together so you spend hours looking for it. Anytime I find a threaded hole without a bolt I'll try and find a bolt to fit it.

Sorry, my initial post misstated the situation slightly. Two of the many holes are actually threaded and putting the bolts back in was my plan. The remaining 8, or so, holes are probably there because the PO ran wires for off road lights. I discovered this last night after making my initial post.

Thanks for your suggestions.

tap them if they are small enough, and fill them with bolts.

Almost any auto store (kragan, autozone, o'reilly,) will have solid grommets in the racks. Same place you find hose connectors, fender shims, door handles, light plugs,, etc

Lowes actually has some plastic and rubber plugs in the nuts and bolts drawers. Measure the diameter and see what you can find. If you have to you can seal it with some sort of sealant.

Most of your local hardware store (Ace, True Value, etc) have a selection of hole plugs as well. You could also use rubber fender washers and bolt/nut them in place.

+1, I just bought several sizes of black plastic pop-in plugs at Lowe's that worked great to plug the stock license plate light wiring holes in my ambulance doors and some small wiring access holes in my roll cage. They even have little springy bits on the edges that hold them in.
