I have moved this to tool talk and i can give you some input.
As always a good set of 1/2 3/8 and 1/4 inch drive sockets and wratchets of both metric and standard kind are a necessity, and good tools can go a long way in this reguard.
Wrenches open and boxed end as well as line wrenches of good quality and different lengths and fitnesses for more leverage or more room are a must.
a good jack with good solid stands and wheel chucks is a good idea.
torque wrenches, inch pounds and foot pounds.
pliers, needle nose, lock jaw, side cutters, adjustable jaw, you name it… they are your best friend.
oil filter wrenches.
screw drivers of assorted kinds, sizes and lengths,
pry bars of different kinds for more room or more leverage.
breaker bars for that pesky bolt that won’t come loose and a good set of impact sockets to go with it, never use standard sockets with a breaker bar unless you want busted knuckles and broken sockets.
a scan tool for reading codes.
then you have some of your misclilanious such as scrapers, sand papers of different grits, carb and break cleaner, WD 40 or RTV or liquid wrench sprays to break loose rusty bolts.
a good drill that you can drill out any broken bolts with a good center punch to punch a center punch to keep that drill bit centered
a good set of hammers can save the day, rubber mallet, dead blow, and good old ball pean
If you have access to compressed air…
Impact wrenches with sockets
Blow guns
If you aren’t afraid of playing with fire and have common sense enough not to burn down your house
Propane torch
a nice big torch
a welder
A FIRE EXTIGUISHER
wet rags
Hope this helps, this is just some of my input.
