I really do NOT enjoy changing spark plugs.

I've done this before on my old Corolla. Loosen each about 1/4 turn, hose some WD-40 down each hole and pick it back up in the morning.
My wife's old Sienna minivan was the worst though. You had to remove the entire intake system to get to the rear head. That thing was a pain in the butt.
But if they feel like they are coming out hard, spray some lubricant down there and move on to the next one while it soaks. I too, use anti seize.

 

Some people prefer to change plugs on a hot engine so that they come out easier.
Many avoid due to being scared of burning themselves on hot metal
Sometimes, if you watch where you lay your arm, or use a towel, that won't happen

 

It is not that difficult.

 

People that have ripped out the threads in a head may disagree with you.

 

I’ve been taught never to change plugs on a hot engine. Especially one with aluminum heads.
The difference in expansion and contraction of the plug and head are different for both, and aluminum is a lot less forgiving when it’s hot.

Maybe I was taught wrong?
But I’d rather be safe with a cool engine.

 

Not only does aluminum expand and contract a lot more than steel, but there's a lot more to expand (when hot) in an aluminum head than in a steel spark plug. I'll take mine cold up to maybe very slightly warm than you. I started working on cars when I was in my teens and let's just say I'm on Medicare now. I've never stripped the threads out of a head yet. Patience (and maybe a little anti-seize) is the key.

 

Yeah. Maybe I’m biased.
I don’t like working on cars/trucks.
And I don’t like working in hot temperatures. Lol

Combine the 2 and it gets worse.

If anyone tells you I work on vehicles because I enjoy it. Reset assured, they are lying to you.

 

If you have never had the need for and never had to install a helicoil, the spark plug issues are minor. All the work that goes into an engine head depends on a threaded hole.

 

I replaced my plugs at 200k and every single one of them fought me. Had to remove the supercharger to get to the driver's side but had to do valve cover gaskets at the same time so it was necessary anyways. What I did was back out the plug to unseat it then sprayed Wd40 in the well and let it sit and applied a little heat gun action. Backed the spark plug out until I felt resistance and then reverse it a turn then backed it out and did that until they were out. It works but it's time consuming.

 

I've done those before on the SVT Raptor. Through the wheel well, over the frame rail and they DON'T want to go in straight.

Why are MotorCraft plug threads such trash? Brand new out of the box and the threads are mushed together and chipped. It's like they put 1,000 spark plugs in a barrel and shake them up when they're making them. Super annoying

 

I started a thread here about how far people have gone on a set of plugs and it's pretty obvious that they will go far further than 100K. Changing at 50K is just unnecessary.

I've never had the pleasure of doing one in an F150 I bet there is no room.
The ones I dread are the 5.4 3v from 03-07, those you always say a prayer that none will break.

Idk I've never had an issue with them.

 

I know when I did them on my 2000 Lightening 5.4 w/Super Charger, it was not fun getting to the rear ones. I think the driver side was the worst. I know one gave me a hard to getting to it.

 

Me too. My first one will be when the temps outside warm up. 40K on the truck. Likely the first ever change on this truck. But - look on the bright side, I have seen many "I did plugs today" posts on TW without any comment on problems. So - may the odds always be in our favor.

 

Y'all should try a Nissan frontier... # 6 is on the back of the engine with about 1.5 - 2.0 inches from the fire wall.

 

I went 100k 0n my 15 with factory plugs without a problem. I read here about changing them some guys said its frustrating as hell some guys said they do all 6 in 30 minutes while drinking a beer. I figured since its my only vehicle i didn't want to call a tow if i screwed something up. I went to a Toyota dealership and they said $400+ not including plugs i said no thanks went to Pep Boys and they charged me $150 with the Iridium plugs i provided i take my chances for another 100k then off to Pep Boys!

 

Glad it worked out for you, but I wouldn't let Pep Boys work on my toilet, much less my truck.

 

A little anti sieze makes the plugs go ‘round nice and easy.

 

I bought a 12 the end of 2020.
Had 137k on it. I changed the plugs figured it was gonna be hell.
The NGK plugs were a little sticky but the denso plugs came right out.
Really wasn’t as bad as I’d read here.
My 08 was a 2.7 and wasn’t bad either.
Not sure why I’ve brought the maintenance up to date I don’t think the frame will fail in time.
But probably soon after, it has some rust.
My 08 was boned and totaled so I grabbed the best I could.

Plugs on left side are ngk.
Plugs on right are denso.

 

Interesting differences in both electrode wear and amount of carbon build-up on the threads from one side to the other.
