Tools & Fabrication - "Just in case tool bag"

Trying to put together a tool bag to keep in the car for when something unexpected happens. So im trying to figure out what should be in it. Ive got some stuff but am open to suggestions.

I don't typically carry "tools" but I do carry an extra belt, fix-a-flat, and a mini air compressor.

depends on the car...

normal car just gets jumper cables, an LED flashlight, a multi tool (cheap knock off leatherman type thing) and one of those flip around 6 way screwdrivers, race car same deal without the jumper cables. Parts chaser/truck/tow vehicle has all that, straps, 30' trucker's chain, a bunch of network cable (use it for tieing stuff down), and my jy crawling tool kit which has a couple of vise grips (one with the 3 sided nut grabbing jaws), a pair of dikes, a cheap socket set that I dont care about loosing...

i go to wallyworld and buy those cheap ass mech tool kits to keep in the trunk.

do you carry tools to put the belt on?

I carry

1/2" LONG ratchet with a lugnut-sized socket
7mm hex driver
flat+philips tip screwdrivers
10mm, 12, 13, 15, 17mm sockets 3/8 drive
same size ratchet wrenches
Klein crimper/wire cutter
Spare fuses
Maglite
8" and 12" crescent wrenches
Channel locks
Small ball-peen hammer
Duct tape

Fits in my 16x4x6 tool bag no problem (1/2" snap-on flex-head ratchet fits folded inside), never had to call a tow truck.

I drove a '96 S-10 for a while, and I'd never know when I'd have to replace a radiator or pound in a tranny seal on the side of the road, haha. Probably why I carry what I do.
Lots of water bottles on a long (200+mi) trip, just in case.

do you carry tools to put the belt on?

You don't need tools to put an F-body belt on :D Left palm pushes on the tensioner pulley, put your weight on it, right hand slides the belt under the water pump pulley.

I don't carry a general mainainance tool kit in my cars, but I did put together a small tool kit for changing nitrous bottles and jets, that I kept in my Z28.

.357 magnum and cash. Solved every problem I've ever had.

a tire plug repair kit,plug in 12V lite,and a belt tension wrench for the DD .a 9mm has more in the clip.

A good set of mechanix gloves, a harbor freight tow rope, a dog bone multi wrench, a multi bit screwdriver, a 24oz. plastic cup, and a tire pressure gauge.

do you carry tools to put the belt on?

No, but I figure it is a hell of a lot easier to find a set of sockets then a specific belt....possibly in the middle of the night, or the middle of nowhere etc.

Belt tensioner wrench, extra belt, and a 9mm with a box of ammo.

I have a complete tool set in my car, but thats only due to me working on something every time I turn around. I was getting tired of not having what I needed so I just packed a little bit of everything. Complete set of standard and metric wrenches and sockets, screwdrivers, pliars and vice grips, fuses and electrical connectors. Just a bit of it all.

I have a complete set of tools as well. Just in case anything happens. Better be prepared than sorry
