A submachine gun (and ammo) for every member of the group is also nice along with spares for those... with local government permission, naturally.
I was planning on using plain ole water for cooling in case of failure.
So here is the updated list - I decided to keep the brake pads since I will most likely need a new set and I don't know how hard it would be to source them.
For the coolant hoses I was thinking of only the ones that can get hit or
punctured. I'm not sure whether any of the smaller hoses would experience a failure.
The largest item in the spares kit is the CV axle and the FJ is pretty small for an expedition vehicle - should I just take the CV boots?
I also had a question about repairing brake lines on the trail, as in, is it even possible? I can see a brake line getting pulled off in the bush. Unless I took a set of spare brake lines I might be SOL if that happens.
For the larger items like water pump/starter/alternator/fuel pump I have decided to either find them locally or have them shipped in case trouble. Chances are these are not going to break on a new car.
I have also assembled a recovery kit.
To take for sure:
Upper and lower radiator hoses - prone to getting hit by rocks
Epoxy for radiator (Waterweld)
Serpentine Belt - prone to getting hit by rocks
Fuel Injector cleaner - in case of bad fuel
CV Axle, R & L seals - CV boot can shred, axle can break
Spare Keys - forgetful...
Tire fix kit - most likely failure
U-Joints - front & rear
brake pads - wear part, we'll be driving 50k+ miles
touch up paint
Leave at home:
Idler Pullies 1,2,3
Cigarette lighter jumper cable (Useless?)
Intake Gasket - have to remove the intake to do anything to the engine...
