Ethos 0 Posted July 22, 2008 Hi guys, Anyone got one? Seems a steal at that price. http://www.argos.co.uk/static/Product/part...RQUE+WRENCH.htm Mate says his is still accurate after 5 years of use! I'm thinking about changing my spark plug soon so want to torque them up (27NM). 28NM would be fine, it's only an ALU head... Share this post Link to post Share on other sites
ashley peddle 3 Posted July 22, 2008 never used one for spark-plugs always just 'nipped' them up and never had any problems? Share this post Link to post Share on other sites

ifcho 0 Posted July 22, 2008 It looks like exactly the same as the chinese torque wrenche I just bought....similar price also... The strange thing is it actually measures accurate...I checked this in a local workshop with two other torque wrenches. Share this post Link to post Share on other sites

welshpug 1,657 Posted July 23, 2008 (edited) less than a tenner from Aldi's Personally I;d spend a bit more and get a 3/8" drive wrench to cover the lower torque specs and a 1/2" drive one for the higher ranges (headbolts etc) Edited July 23, 2008 by welshpug Share this post Link to post Share on other sites
Tom Fenton 1,542 Posted July 23, 2008 Please please please do not torque up your spark plugs. It is really not necessary, and if you bust one off you really will be crying into your soup. Share this post Link to post Share on other sites
Ethos 0 Posted July 23, 2008 I know you can just "hand tighten" then tighten properly half a turn but I thought with an ALU head it'd be safer to torque them up.... Why are you so against torquing them up Tom? Welshpug, I think you are right. I'd like to buy the 2 from halfords prof range, £49.99 each. Now i've started doing more on cars I really want a good set of tools, it's addictive! Share this post Link to post Share on other sites
ifcho 0 Posted July 23, 2008 I think that the 28Nm (That is the min of this wrench are too much for a spark plug) I undo spark plugs with a 1/2 ratchet, but tighten them with a T-type spark key to make sure I don't over-do them Share this post Link to post Share on other sites
ablister 31 Posted July 23, 2008 Please please please do not torque up your spark plugs. It is really not necessary, and if you bust one off you really will be crying into your soup. how can it break if you torque it? If anything, you should be encouraged to torque them to stop it from being overtightened... Share this post Link to post Share on other sites

Ryan 99 Posted July 23, 2008 Please please please do not torque up your spark plugs. It is really not necessary, and if you bust one off you really will be crying into your soup. Torquing them up means doing them up as tight as they need to be. Why is that going to break anything? Just because a torque wrench is the size of a breaker bar doesn't mean everything gets done up to 600 ft.lbs. Share this post Link to post Share on other sites
24seven 104 Posted July 23, 2008 (edited) no but a torque wrench that starts at 28Nm is going to overtighten your spark plugs. literally they only need to be hand tight, then 1/4 or 1/2 turn again. It's the minimum you can get away with without them coming loose. undertightening them isn't the end of the world. they'll come loose, rattle a bt so you just nip them back up. if you overtighten them and one breaks, you've got a problem.

Tom Fenton 1,542 Posted July 23, 2008 If you guys want to torque your plugs up then don't let me stop you. But I don't and never will do so myself. Do you believe that a cheapo torque wrench will be accurate at or below the lowest extent of its working range? If so then you must be more optimistic than I am. Do you also believe that 15 year old threads in an alloy cylinder head are still in as good a condition as when the torque setting would have been deduced when the thread was newly formed? I personally don't believe this either. So your choices are as such; follow the spark plug makers recommended tightening procedure, (which is to screw the plug down till it contacts the seat, then an additional 1/16 of a turn for cone seat plugs, or an additional 1/4 of a turn for plugs with a crush washer) or go ahead and torque away to your hearts content. Personally I've never experienced any problem with plugs being too "loose", but I've had to sort out plenty of problems not being able to get a plug out, plugs shearing off, or dealing with damaged threads.

gti-si 0 Posted July 23, 2008 Agreed. It's just not worth the hassle of getting a torque wrench out for spark plugs, especially when there's a greater chance of over tightening. It should be very easy to deduce when a spark plug is tight enough with feel alone, it only needs to be nipped up enough that it doesn't work itself free from engine movement, which isn't very tight. Just use the T piece plug removers, they're designed with little leverage for a reason. Share this post Link to post Share on other sites

Thanks for explaining Tom, I understand where you are coming from now and have to agree with the points you have raised Regarding the accuracy of the torque wrench I know two people that have had that same model for 4-5 years and they are still accurate to this day!

jimistdt 1 Posted July 23, 2008 Surely as aresponsible retailer it is in Argos' best interest to make sure that the Torque Wrenches do what they say on the tin? Admitedly a professional mechanic wouldnt buy one to use on a daily basis, but as a hobbyist surely they meet the criteria. I could have done with one the other day when I changed my gearbox oil, but as it was I didnt have one and I guessed, so in this instance is it not better to have a reasonably accurate tool for the job, alright they are not 'Snap-On' but sufficient for most?

KRISKARRERA 2 1 Cars Posted July 23, 2008 Yeah though if you wrecked the threads I reckon you'd have a hard time getting Argos to pay for repairs! Funnily enough I've always used that spark plug tool with the T shape handle and then my dad bought a Halfords "professional" torque wrench that goes down to 5lbs or something, so I used that, set to just 7lbs and I discovered even just 7lbs was ALOT tighter than using the spark plug tool so next time I'm definately not using a torque wrench.
