I%26#039;m 16 and I have my first car thats an old beater. my friend said i should change my spark plugs cause it%26#039;s old and i%26#039;m like cooll.. lets do it. so anywaz he says that i should tighten by hand only otherwise they might crack and break like when you change the oil filter. Is that true?|||NO. You should only start them by hand so you don%26#039;t strip the threads in the head, but once started they need to be tightened properly with a spark plug socket and ratchet. If you have the right tools, then tightening them without breaking them shouldn%26#039;t be a problem.|||Yes, hand tighten only!|||Yes, each plug has a specific torque that it should be tightened to to avoid damage to the plug and to the manifold itself.|||It is easy (and bad) to overtighten, but you should be tightening more than just by hand. Ideally, you should buy a torque wrench. Spark plugs are supposed to be tightened to a very specific torque, and using a torque wrench is the only way you can be sure you%26#039;re getting it right.|||its kinda true, tighten by hand but with your ratchet, tighten them wrist tight. u def want them tighter then just by hand, but just wrist tighten them with the ratchet. not to tight though. make sure u gap all the spark plugs the same before u put them all in.|||yes only hand tighten your plugs or the could break off in the head which is bad. you want them snug yes but don%26#039;t torque on them.|||get a bok on your car it will tell you what to and whatNOT to do make a mistakeand it will cost you more than the book to putright|||when putting in new plugs, hand tighten them first to avoid cross thread. Then when you use the socket go by torque spec or tighten them snug. I would also throw in a can of seafoam for your car. That will bring it back to life. Lots of video%26#039;s of how to use sea foam on cars in youtube. Anyways good luck.|||Ideally use a torque wrench.
Plus are tightened dependent on the type of engine.
Most are tightened to around 12lb/ft.|||Lots of good answers, first after sett ting the gap, you should use just a little bit of anti-seezing compound on the threads. You can easily seize one( especially ) in an aluminum head, then you got BIG trouble. Jusl a little !! Then thread it all the way by hand, and finish it off with a little tighten with the ratchet handle, but not too forceful. You can go too far %26amp; strip out the threads, especially on aluminum.|||hand tight and then about another 1/2 turn with the socket.
