98 Intrigue spark plug changing

[355890]

I was trying to change the sprak plugs in my 98 Intrigue. However when I stsrted trying to pul the plugs covers out there was a metal cover over the pugs and was unable to get to the plugs themselves so as to replace. Can anyone help with instruction on how to get to and replace the plugs. Thank you

Step 1- Pull the plug wires off, when you pull the plug wires off discard the metal covers and ' DO NOT USE THE METAL COVERS"
Step 2- replace the plugs with the same A/C plugs as orginal
Step 3- replace the plug wires with a new set
Step 4- You will never need to replace plugs or wire for the next 100,000 miles
Step 5- Have a few beer

Why do your discard the metal shields?

They serve a purpose. To shield the spark plug boot and plug from heat and are used for anti-static suppression due to the high voltage which may be picked up by the sound system and other electronic components.

Usually a good guideline, but far from 100% true...stuff happens

But yes definetely put those heat shields back on, it gets very hot back there on the firewall side of that engine, and like bnaylor said, they are there for a reason.

In most cases I agree that the orginal stuff should go back on. In this case I talked to quite a few mechanics and the discard the metal shields the cause more problems then they are worth. The new quality plug wires can handle the heat.

In the end whether you decide to keep or discard them is a matter of personal choice.

All that needs to be done after the spark plugs and/or wires are replaced is to coat the boot with hi-temp silicone grease which will make removing the shield easier on the next sevice. The OEM Packard 7mm silicone plug wires were made to handle the heat, good for at least 100K miles, and some of the best on the market but the GM Engineers decided to add the heat shields for a reason so I keep mine.

How do you get to the plugs on the firewall side of the engine. I changed the plug wires on the front of the engine, but can't seem to get back to the other ones. Is there a trick?

Thanks,

the back ones are pretty much done by feel, it sucks, but can be done, you should also be able to rotate the engine forward just a tad by removing the top engine mount on the radiator support, and then pulling forward on the engine, using...something? I used a come along attached to a pole.
