97loudcut Posted May 10, 2006 Report Share Posted May 10, 2006 Sorry I am in a HUGE hurry so I didn't have time to search. I am going to be doing a tune up on my 3100 SFI Cutlass and I need to know the materials I will need. I know I want to change spark plugs, plug wires, and the fuel filter. The car has 116k miles and I don't know when its had it last tune up. Is there anything else I should replace. I also need a list of the best (not most expensive but a good product) things to buy. So basically what spark plugs, what wires, what fuel fiiter, and anything else you guys can think of (such as coilpacks.) Like I said I don't even know if this thing has ever had a tune up. And finally what gap are the spark plugs. Thank you guys (plz dont kill me with the "no search") Quote Link to comment Share on other sites More sharing options...
ToroToro Posted May 10, 2006 Report Share Posted May 10, 2006 AC Delco plugs...the cheapest ones are fine. Autolite wires are decent for the money, and I just use fram fuel filters. Might want to replace the PCV valve too, just because... I wouldn't replace any coils unless you know you have a bad one. They aren't cheap. Plugs are already pre-gapped if you buy AC Delcos.

fastbird232 Posted May 10, 2006 Report Share Posted May 10, 2006 ...or if they're not, the gap is listed on your emissions sticker in your engine bay. Quote Link to comment Share on other sites More sharing options...
Euro Posted May 10, 2006 Report Share Posted May 10, 2006 which it should be .45( i think..or .045 i cant remember exactly ) Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted May 10, 2006 Report Share Posted May 10, 2006 Id use all AC Delco plugs, wires, and filters ( except for the K&N air filter ) I cant remember if the gap is .045 or .060, its been a while since I replaced plugs on my car. but as mentioned above, look there and that will help you out there. Id just do an oil change while your at it as well. Quote Link to comment Share on other sites More sharing options...
BandaorICE Posted May 10, 2006 Report Share Posted May 10, 2006 When I tuned up, I replaced my Spark Plugs (AC Delco, NON-Plat), Plug wires (AC Delco), Oil Filter (AC Delco). If your going for a major tune up, Don't forget your Serp Belt, Gaskets, Coolant, Trany filter/ fluid, PCV valve, Check the vacuum lines, Fuel Filter, And if your getting in deeper.... Fuel Injector O rings, intake gaskets. Don't think it hurts to put new ones on. Quote Link to comment Share on other sites More sharing options...
joey b Posted May 11, 2006 Report Share Posted May 11, 2006 pretty sure gap is .060 for the 3100 Quote Link to comment Share on other sites More sharing options...
89GP_SE Posted May 11, 2006 Report Share Posted May 11, 2006 I know I want to change spark plugs, Put spark plug socket on spark plug (be sure to remove plug wire first) then turn socket wrench to left (remeber this rule : Lefty loosy, righty tighty) plug wires, Soo Easy, just pull them off the spark plug and off coils. and the fuel filter. honestly, never done it Im just kiddin, but you did say you wanted to know how, know you know LOL Quote Link to comment Share on other sites More sharing options...
jeremy Posted May 11, 2006 Report Share Posted May 11, 2006 you will need a fuel line tool to remove the fuel filter Quote Link to comment Share on other sites More sharing options...
sl3196 Posted May 11, 2006 Report Share Posted May 11, 2006 you will need a fuel line tool to remove the fuel filter Nah just two wrenches. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted May 11, 2006 Report Share Posted May 11, 2006 you will need a fuel line tool to remove the fuel filter Nah just two wrenches. x2. Ive never used a fuel line tool to get that off. just two wrenches and your good to go. Quote Link to comment Share on other sites More sharing options...
94CutlassSLCoupe Posted May 11, 2006 Report Share Posted May 11, 2006 you will need a fuel line tool to remove the fuel filter Nah just two wrenches. I believe its either a 16 or 18mm flare nut wrench on the steel hard line (don't use a regular wrench) and just use a crecent wrench on the fuel filter. The other side is just a quick disconnect where you push in on the two little tabs. I would do AC Delco Plugs and OEM wires from the dealer along with a Purolator Fuel Filter. I'd probably seafoam it before doing this and also, if the intake gasket has never been replaced, i'd do that. Quote Link to comment Share on other sites More sharing options...
jeremy Posted May 11, 2006 Report Share Posted May 11, 2006 the fuel filter should be 20mm....and I guess that I am the only one the used the tool for the quick connects ....it was only $3 Quote Link to comment Share on other sites More sharing options...
97loudcut Posted May 11, 2006 Author Report Share Posted May 11, 2006 okay well i got a price of $115.00 for the materials for my tune up and they go as follows.. AC Delco plugs - $5.99 x6 AC Delco plug wires - $59.99 (lifetime warranty) Fram fuel filter - $10.99 PCV Valve - $2.99 Is there anything else I am missing. Also are the plugs .060 or .045 need to know that. Finally my uncle (an amazing mechanic) is going to help me seeing as this is my first tune up. He wants to know if it is an "in-line" fuel filter, and how hard it is to replace. thanks alot to everyone who gave me good advice, you are all eally helpful.

jeremy Posted May 11, 2006 Report Share Posted May 11, 2006 yes, it is an in-line fuel filter Quote Link to comment Share on other sites More sharing options...
97loudcut Posted May 11, 2006 Author Report Share Posted May 11, 2006 okay glad that was established. so does it make it hard to do and how do youdo it on a 3100? Quote Link to comment Share on other sites More sharing options...
THe_DeTAiL3R Posted May 12, 2006 Report Share Posted May 12, 2006 The fuel filter is a simple job, however it may be rusty so you might have to fight with it to get the bolt off. The one "quick connect" or whatever you call it on the one side of the filter is easy though. Unfortunatly mine was rusted so bad, that the bolt was just stripping and bending the fuel line. I cut it off and put some rubber line along with the new filter and several clamps for good measure... 3100 is a pretty easy engine to work on, only thing I'd suggest is if you are changing your t-stat that you take off the throttlebody. That is all. Quote Link to comment Share on other sites More sharing options...
BandaorICE Posted May 12, 2006 Report Share Posted May 12, 2006 1996 and later 3100 spark plugs (according to this manual) Are:: AC type 41-940 or equivalent@ 0.060 Quote Link to comment Share on other sites More sharing options...

19Cutlass94 Posted May 12, 2006 Report Share Posted May 12, 2006 '94 3100 AC plug is R44LTSM6. The fuel filter is a simple job, however it may be rusty so you might have to fight with it to get the bolt off. The one "quick connect" or whatever you call it on the one side of the filter is easy though. Unfortunatly mine was rusted so bad, that the bolt was just stripping and bending the fuel line. I cut it off and put some rubber line along with the new filter and several clamps for good measure... Also when changing the fuel filter, dont take it off all the way until the pressure has been relived. or else youll get a face full of gas Quote Link to comment Share on other sites More sharing options...

Unfortunatly mine was rusted so bad, that the bolt was just stripping and bending the fuel line. like mentioned earlier, DEFINITELY use a flare nut wrench, not just a normal wrench, to try to do everything to avoid stripping the bolt...

5speedz34 Posted May 12, 2006 Report Share Posted May 12, 2006 Are those platinum plugs? I would probably just get the stock copper ones, now use spending $5.99 a plug! When are you doing this? Hit me up, if I have time I could come and help no problem. Quote Link to comment Share on other sites More sharing options...
AWeb80 Posted May 13, 2006 Report Share Posted May 13, 2006 FYI...I got the ACDelco wires for my car from GMpartsdirect and they were ~$35 shipped to me....not $60.....and you dont need to replace the PCV valve as long as it rattles.....but then again, it is only $3.
