I noticed the 2001 1.6 L engines have 2 wires and 2 modules held in place with 2 bolts. I did not have the right size and was wondering what socket fits to remove those bolts. I am in the process of replacing my sparkplugs but need help with the size of the bolt. I think its greater then 9mm and I lost all other sizes even close after that, so.... I just wnat to buy the right one. Thanks in advance!

I don't have a 2.0L and I can't answer this question directly, but almost every small bolt found on 99+ Proteges is either 10mm or 12mm. Buy both, you'll need the other one eventually.

Thanks carguycw, I'll just buy a good set and I'll let evrybody know. So far sparkplugs on this car looks easy with the right sockets Anyways, thanks!

P.S. Mines a 1.6L, not a 2.0L also

i do believe a 10mm socket is required for the removal of the coil packs.

A 10 mm sized socket or wrench can be used to undo about 90% of the bolts and nuts on a 3rd gen.

just a tech tip:

japanese machinery usually uses 8, 10, 12, 14 & 17mm for most of their fasteners. they also usually use a fine thread.

german machinery usually uses 7, 9, 11, 13, 15, 17, 19mm for most of their fasteners. they also usually use a course thread.

american machinery uses a mix and match of fasteners.

i used to the term machinery because their fastener sizes seem to apply to anything built in those countrys.(cars, motorcycles, chainsaws, etc)

Thanks guys! 10mm was the right size! The change was really easy on this car. Actually It was the easiest of all cars I have done. Saturn SC2 94, Merc Mystique 98, Merc Topaz 92, Plymouth Voyager 98,! I installed the Plat 2 BOSCH. I Did not notice any difference in startup, fuel economy or anything as of yet The DENSO's were in top shape. They had 40000kms on them and they looked great. I'll probably go back to the DENSO's when I am done with these BOSCH 2's (Hey they were on sale ) The Plat 4 were not! Either way, I think I proved to myself that simply changing from DENSO-NGK-BOSCH does not make much or any difference and is not worth the extra money. I did love the look of those DENSO's. THey were all the same colour and all had next to no real wear on them. Are those Japanese plugs? I never saw these plugs before!

I believe Denso's are japanese plugs - but they are a major company, not some newbie - they've been making high-quality spark plugs for years.

And thanks for proving a point - that swapping to some super-fancy whateverthehellyoucallit spark plug is WORTHLESS. No spark plug on the market today is going to increase performance all by itself. Same thing with wires, or even combining the two.

Stock wires and plugs are more than capable of handling the electrical energy produced by the coils. Changing to anything else is just a waste of money.

At least you got yours on sale!

I am convinced with my stock plugs (denso) and am glad the weather was as good as it was. This allowed me to change them myself. I was contiplating a garage, but the weather improved drastically! Anyways, that topic is put to rest, for me anyways
