Hey guys so today i went and got spark plugs i was able to put one of the Trailing plugs in the front wheel. The other one i couldnt open OMG i cut my hand and was still unable to open it. The other rear 2 i could not find for the life of me i look up the pictures still couldnt find them..

My question is i called Mazda they said they will chard 110$ to put spark plugs in
will they VOID my warranty if i tell them that one of the plugs doesn't need to be changed?

 

Changing spark plugs won't void your warranty.

 

Did you look at DIY section? It will let you know the tools too. Where do you live...maybe some one on here can give you some direction.

 

How you could "not find" the plugs if you had managed to find one of them is beyond me .
Sounds like DIY is not your thing so you are right to get Mazda to replace them .

 

^ I aggree

Plus you may have put the trailing plug in the wrong spot.

 

They are all within 4 inches of each other. How could you find one and not the others? FYI I did plugs, wires and coils yesterday. Take the front wheel off (drivers side) its a lot easier that way. Use jack stands (at least 1), or you could really hurt yourself.

That $110 would be for an hour's labor, which is a typical minimum but a lot more time than they really need. I suggest you ask them to take out and check the one you did put in, just to make sure it's OK.

The only risk you face is if the service guy likes to make fun of failed DIYers. But most good mechanics are sympathetic. (Don't ask how I know that.)

just raise the car, take off the wheel ... trust me you'll see all 4 plugs and end up cursing yourself of how you couldn't see them before....

 

The other set of plugs is easier to reach from under the car.

You can get more leverage by putting a short length of pipe over the wrench handle. But do be careful -- it is possible that the old plug has seized threads, in which case things can get expensive real fast. If you can't remove with a reasonable amount of force then you may be better off having the shop do it. They'll have better luck with recalcitrant plugs. And if they do rip the threads, the repair is on them.

If you manage to DIY, make sure to use anti-seize compound on the threads, to prevent stuck plugs in the future.

 

yeah, a $100 isn't that bad...

if doing the job "right", i would've taken ALL plugs out, seat in ALL new plugs at the same time, hand tighten, then follow torque specs or "snug" them down according to NGK's recommendation(1/2-3/4 turn) on the box.

and don't just have only half of the plugs anti-seized... get all four.

its ok to f up once in a while, we're all human. why else is the club here?

get it sorted out or done correctly. you don't want this to turn out to be $100 you've regretted on NOT spending.

and if you plan on having a routine engine clean, now would be the time to seafoam/ fuel injection cleaner spray ur motor.
