rusted spark plug problem

RE: 1996 Explorer

I have a potential problem here. I have changed out all but one spark plug at 67,000 miles because it has rusted in (2nd from the rear on the passenger side). I have been using liquid wrench and moderate force and even a few seconds with an impact wrench. It will not budge. I am worried that it may break off in the head so I am looking for anybody with experience.

Thanks in advance.

You might try it with the engine at normal operating temperature.

rusted spark plug problem

I recently changed out the paasenger side exhaust manifold. I soaked at the bolts good with PB Blaster. Over a 24 hour period, I resprayed the bolts every couple of hours. When time came to remove them, I couldn't believe how easily they turned.

After a good soaking, you could try tightening the plug a hair to try to break it loose and then try unscrewing. This would be a gentle rocking motion.

Once you get the plug off, always used an anti-seize compound on the new threads.

Hope this helps

How did you get the 6th plug out (the one closest to the passenger). I am stumped.

blend-door.... go through the wheel well. You might have to remove the splash shield, but once done... it's right there.

You can also reach up (with engine very very cool) from under the passenger side, you'll have more room unless you're double jointed to actually move your arm on the ratchet..
