Is it really that hard??

Hey everybody. I'm still kinda new to the mechanics world. Lol. But I'm wanting to do my first full tune up to my Mustang myself. But I've heard horror stories from the heads and plugs. Is it really that bad? Just thought I'd get some insight. All input is appreciated! Thanks!

No. I did mine and I don't have any problems. Just be careful when u put them back in.. Make sure they aren't cross threaded.. I Put them in then startin tightening them by hand (with an exstention) to make sure they were goin in right them tighten them down..

I did it on my 01 GT and took my time and was very carful and I still blew two spark plugs. Not at the same time but I had to have one heli-coiled from Ford but the mechanic at Ford said it looked like I did them right and used the right plugs.

Yea my 02 GT has 90kmiles on it and it's time to do it on this car. My buddies F150 did it too and Ford changed them out and they wouldn't replace his heads they just heli-coiled it too. I guess just be careful and use the stock plugs you might have more luck than me, plus I don't know if the last guy who owned the car changed them and damaged the threads. Fords buggiest mistake on these cars was the threads for the plugs.

The 96-98gt is a little tough to do plugs on but if your careful (and get a good spark plug socket!!!) You'll be ok. Some guys take the fuel rail off to give them better access. The passenger side is a bit of a ***** for sure! Make sure u use quality anti siez compound and good electric grease and u should be ok. Take an afternoon and be prepared to take things nice and slow. Do as much of it by hand as u can to avoid thread damage. I used high quality iridium tipped plugs. Make sure they are gapped perfectly tho because one of mine wasn't.

Not that bad of a job. Something that might make it go a little smoother that I would recomend, after you remove the wires from the plugs, spray a little PBblaster down each hole. Let is sit for a bit, then remove the plugs. Definatly take your time.

I literally just did mine on my 98 v8 and it went without a problem. It runs So much better now to because i had a misfire and leaks and such. I cant afford to not have my mustang running either but i got this done in a few hours! Just take your time like they said! Get a goooood gapper. Not that cheap circle thing. Doesnt have to be Great either but nice and durable. Also, when i pulled them, i noticed a part of the rubber boot that goes over the plug got severed off. Dont let that happen to you! Just take your time, maybe get some boot pullers, although needlenose works to, and be gentle. Your workin on the 3rd most important instrument in a car! Besides fuel and oxygen! Btw i got double platinum because iridium didnt seem like it was worth the jump in cost. As well as E3

I got my mustang from my brother in Oct. And havnt done anytjhing to it myself, but he complained about how annoying they were to work on the whole time he had it. The way he made it sound anytime he had to change something he spent more time taking off other parts to get to it then actually fixing it, but that was mostly not engine stuff.

If theyre annoying dont have one! I Love working on my car. Its awesome. And im willing to invest time and energy into making it run better or look nicer. That goes with most people with mustangs. Especially on this forum! True, you do have to take some stuff off to get to others but thats with every car! And if you aint willing to get your hands dirty, dont get the car and expect to be "in tune" with it.

As I said, that is what my BROTHER told me from his experience working on my car, and clearly he doesn't have it anymore if he sold it to me. Lol

Yeah it's not difficult to do the plugs just have a few extensions different sized and a swivel extension and you'll get them all in and out in a flash but I would recommend doing changing the wires also because I broke one when I was reinstalling and it was missing so bad i thought something was seriously wrong but after a new set of wires firing good on all 8 again.

Re: Is it really that hard??

Just did mine today. Just put a little antisieze on the threads then take your time and run them in by hand first before torquing them down. I torqued mine to 135 in/lbs then just snugged them one last time. Let it idle for about 5 minutes then drove it for about 30 and have no problems. As said above, just take your sweet time and all willl be fine

I think where I messed up was I didn't let the engine completely cool down before I changed mine out and I herd that makes the difference.
