For years I've borrowed friends socket sets, so it's about time I bought my own!

The two immediate jobs I have in mind are; spark plug change and front brake pads/discs on a Smart ForTwo.

The spark plugs need a 16mm spark plug socket and need to be tightened to 22Nm.

So I think I need to buy:

1/2" socket set
1/2" torque wrench (40-210Nm)
3/8" torque wrench (10-80Nm)
3/8" to 1/2" adapter
16mm spark plug socket

Does this sound all OK?
Will the 3/8" to 1/2" adapter fit inside the cylinder head, so should I buy the 3/8" sized 16mm spark plug socket?
Are there any merits in buying a 3/8" socket set?
The tools are just for infrequent car DIY so don't need to be of the highest quality.....just not rubbish as to round off the nuts.
I don't want to start the job they realise I'm missing a vital tool ;)

Thanks.
 
For much of the work done on modern cars a good quality 3/8 drive socket set will be fine up to 22mm and is often better for access -just make sure you have a decent range of sizes in the larger 13mm and above sockets- preferably some deep ones too. I would go for the 6 point surface drive type if you can afford it . Good intro here DIFFLOCK.com - Socket Sets plus some recent reviews Torque wrenches tested | Products | Auto Express

get the halford one got all bit
 
The halfords kit is superb for a home mechanic.

If you are doing the plugs on the Smart you will need the tool to remove the plug caps. Dont forget there are 6 of them too.

Do you use 3/8" or 1/2" sockets when working on Smarts?
 
Depends on what Im doing.

Generally 3/8.

We tend to use alot of air tools that are mostly 1/2
 
Agree 1/2 tools are a waste of time on cars in the engine bay, 3/8 are superb, halfords tools are pretty good.

Ive got some of their ratcheting spanners and seem okay so far, not as good as snap on but nowheres near the price:), also got some of their torx 3/9 sockets which i regularly use on my 1/2 battery impact gune and they are also still fine.

At home ive got a 3/8 drive sealey socket set in a tin thats got all you need apart from the torque wrenchs cost me about £40/50, done all my spark plugs with this set up, even my wheel nuts with a piece of tube slipped over the ratchet:D

Dont buy one of the huge kits as half of the stuff you will never use.

Never though about it like that - but 3/8 for the engine bay, 1/2 for suspension is probably a pretty good rule of thumb.

I survived on 1/2in and 1/4in for years, but bought a 3/8 set from halfords after buying the merc and realising there's much less space than with a 4 pot.
 
Another vote for the Halfords tools here. And if you break them (don't ask..), they will just swap them.

3/8 is the best for all round work. A torque wrench is useful, but make sure the threads are clean and free running before you trust it entirely....
 
Get the trade card at halfords makes quite a difference to the prices.

I bought the Teng set that was advertised on here.. ok it wasnt cheap but I have every manual tool i could ever want..
 
Don't see why you'd need two torque wrenches. One has served me well for years. Buy the 1/2" torque wrench and then a step-down so that you can use it with the 3/8 drive bits. Agree with the others about 3/8 drive though - it'll do all but the meatiest tasks.
 
The new tools have arrived :)

Be careful with that Jack. The overall surface area is not good for jacking up heavy MB's.
