Scary Plug Change
 

Well, after reading all the horror stories, I'm going to pull & replace the plugs in my '06 GT with 38K miles. I have a new set of HT1 plugs,my socket, Permatex nickel anti-sieze and Aerokroil. I am nervous as heck but I figure I've already waited longer than I should have. I am so angry at Ford for this horrible design flaw. I love my Mustang, but I shouldn't have to fear changing the damn plugs. I'd love to see a class action law suit over this, Ford should bleed.

I have experienced this first hand. I broke the first plug on the left bank when I made this jump. You may want to look up TSB 06-15-2. I have it but cant attach PDF here for some reason.

Advice:

1. Get some PB buster or a good penetrate.

2. Get your engine up to operating temperature first THIS IS VERY IMPORTANT. When you get up to temp drive it a few More miles to let it heat soak.

3. Pull all of the coils, as you do squirt some penitent in the hole.

4. Use a torque wrench to remove the plugs do not exceed 25 ft lbs of torque while removing. If you do stop use more penitent.

Mystang,
I'm surprised this job should be done with the engine heated up. I always read with aluminum heads the plugs should be removed with the engine dead cold.

It's the least of 2 evils. The carbon-soot will be softer when warm. You don't want the engine REAL hot. Just warm. Let it run for a few m inutes is all. Note that the engine will cool down as you struggle to get them out so allow for some cool down time or just restart to warm back up.

whats the problem? I have never heard of anything happening with the plugs? will they break or something? I would like to know.

RE: Scary Plug Change
 

Yes, they wil break. It iscommon. Carbon cements them into the head.

I talked to the dealership service dept. today. He said yes, he had heard of this problem, but that it is much more common in the 5.4L in the trucks. God, I hope this is so.

He's lame. We have the same heads. Same design. Same problem.
