Where are Mazda 3 plugs?

Answer 1

if you are talking about the "spark plugs" pull the plastic cover off the top of your engine. you will see four wire harnesses in a horizontal pattern. disconnect the harnesses from the adapters. the adapters are bolted down. the bolts look funny. they are a nut PERMINATELY connected to a threaded rod. lets call them "bolt-rods". a few of them will have clips on them. these clips are for the engine cover. pop them off and remove the bolt-rods. the adapters pull right out. with a flashlight, you can see the sparkplugs deep in the holes. Oh, DO NOT MIX ANY OF THESE PARTS. EACH ONE NEEDS TO GO BACK EXACTLY WHERE THEY CAME. the sparkplugs require a special socket to remove them. they have a ceramic sleeve on them. if you crack it, peices may fall into your cylender. over a short time, this will DESTROY your engine. If you do crack one, use a vacuum to suck up the shards before completely removing the plug. replce the plugs with newones the same size. there are a lot of different types of spark plugs on the market. find some that suit you. install those plugs. be careful not to cross thread the hole. again, very bad if you do. use the socket without the wrench to get the plugs halfway screwed in. then tighten them snug. do not over tighten the plugs. that will shatter the ceramic. install the adapters, bolt rods, wire harnesses. this is critical. the wire harnesses must be plugged into the right adapter. otherwise your engine will missfire and run bad. install the clips for the engine cover and press the evgine cover into place. done!
