Default Spark Plug Change....hot or cold?

Which is easier to change the plugs, while your car is hot, or cold? I know a lot of people have trouble the first time, I think these are original plugs, the car has 40k on it. Thanks in advance for any help!

Personally - I always preferred to do it cold, only because of not burning my delicate fingers. But I suppose with an all aluminum block, if it was hot it might be easier to break the plugs loose......I guess I'd still do it cold.

You don't want cold air pouring into a hot cylinder through the plug port.

Bro like I said over MSN, do it with the engine cold. Use that double swivel socket and long extension and start out with plug number 7. Pull the wires from the boots and not from the wires themselves. Take your time. If you run into any problems, give me a call and I will walk you through it

Good luck! I know you will get'er dun!

Actually doing it cold has merits because of less chance of sticking in the threads. Meaning you won't pull them out with the plugs when you back them out...

Nouman is right on, OF course!! Ask him how many times he's changed plugs in his baby!! Err...maybe how many times Oak has changed them???

I have to wonder though Nouman... Doing # 7 first?? WOW... Poor Shannon, he will be cussing in no time but at least the rest is cake after you get past that one.

Also, Shannon, get some wires too!! Don't mess around with old wires... Yours are 6 years old!! They are hard to pull off, you tear or break one partially and it's now a problem... Get new wires and be done with it!!!

Got 7 done.

Another Q??? Is it best to pull the plug wire boot to get it off, or the aluminum shield?

How much are wires at a local store?

BTW, Nomy and Oak, answer your phones!

I too have always heard to change the plugs when the engine is cold on these cars. Going to find out soon since I want to change my plugs.

Shannon sorry did not answer the phone earlier.

I thought about telling you about the new wires but I knew you were tight on the budget. Oak still has my old wires if you want to ****** them instead of buying the new ones.

But do as I told you over the phone with the wires that you are getting. No clarification required here I hope.

Call me anytime if you have any other questions!

Some experienced GM service managers have told me that when you install plugs in a hot vette engine, they are very likely to freeze in there after about 50 k miles.

Hmm selling cattle... eating dinner.... Was that a FRESH steak you had for supper Oak??? Nah, I'm sure you'd age that baby for 21 days wouldn't ya? I would!!

Shannon, the wires degrade with time, temperature and such. (I'm sure you know this) It's hard to keep them in one piece when they are a few years old. It's also one of those things that until they get real bad, you really don't know how bad they are...

I hope you put die-electric grease on the new wires for a nice connection? Also, did you use anti-seize on the sparkplugs when you put them back in?

Once again, I did very little to aid in this endeavor...dang...

It is amazing at the difference in HP when going from an old worn out set of plugs to a new fresh set!! That hotter spark works wonders!!

I see you posted this yesterday and you're probably done, but I hope you put some anti-seize paste on the threads before you installed the new plugs. It'll save you some trouble the next time you do a change.
