getting new spark plugs hopefully...heat ranges?!?

SideWinderGX · 02-21-2007, 03:37 AM

gotcha. that NGK linnk was the best one. god, its like a worrywarts nightmare :-X in order to get a colder spark plug, youd have to find out the temperature inside the cylinder (inside 500 and 800C is the best)...but how would you find that out? i think i read something about that in the first\second link, but didnt really tell me...basically, octane, compression, gap, plug elements, and timing all come into play, but im not sure how youd choose to go colder a level or two or three.

not saying im going to, but it wouldnt hurt to know

heeeey, thanks for the link. that says 40 bucks for a set of six...so the spark plugs at supraspeed.com arent for one, theyre for 6? haha i thought it was gonna cost me like three paychecks.

You'll know the temp inside the combustion chambers by inspecting the spark plug after you've run it. Basically the more power you make the hotter the temps and thats when you go to a colder plug.

It's not something to be worried about with a stock engine. You should be saving your money for all the parts and tools you are going to need for that head gasket, now thats what I'd be worring about.

ok, 6 is the stock level of spark plugs...and supra sports plugs are the same (wee, i compared part numbers, im a genius :-P) as the link you gave me, but are 15 bucks more expensive. thanks again!

yeah, i am saving for the headgasket job. maybe another month and ill have about a grand. but, i wont be able to do it myself, im not that good with engines yet and i DEFINITELY dont wanna mess anything up...my friend said shed get me a deal with her mechanic who fixes her eclipse. one of the packages on suprasport for the headgasket repair has a timing belt in the list...i dont really need that, just a headgasket and studs, right?

Yeah change the timing belt while your at it. Its only like $30, I think.

SideWinderGX · 02-21-2007, 04:49 AM

whats the timing belt do, anyways?

edit: crankshaft to camshaft...got it.
edit again: erm...is it the same as a serpentine belt? just two different names for the same part? i know what a serpentine belt is haha, me n my dad replaced it on my 94 saturn.

Timing belt and serpentine belt are 2 separate items.

Timing belt drives the cams. It's cogged.

Serpentine belt drives all of the accessories, like water pump, alternator, power steering pump, A/C.

Mk3's do not have a serpentine belt, they use individual v-belts. One for the water pump and alt. One for the power steering and one for the a/c. 3 in all.

You see that black cover that has that sticker with those letters 7M-GTE? Your timing belt is under that.

Timing belt is cheap but you should also replace the timing belt tensioner. That is $140 and is a dealer only item.
