there is a retaining bracket holding in the lines. But, your information ” which is appreciated ” is misleading anyone that wants to do this. you have to get the pump out of the way to do this job. its best to not leave it connected to any lines while your pulling other stuff out. infact, you cant leave it connected. maybe your thinking of the 3.1L. i forget how much clearance is there on 3.1 pump. but you do need to remove the pump on the 3100’s
ok WHOA do NOT REMOVE POWER steering pump, just remove the cap off the fuel rail by the power steering pump, remove the idler pully from the bracket bellow alt, then pull the power steering upmp straiight up, and just wiggle it back and forth it WILL come out without removing injectors or disconnecting the lines from the pump, you just push the pump off to the side, if i do recall theres a nut holding the lines down somewheres u take off and u get tons fo flex with the lines, DONT REMOVE IT
Yes I forgot about the exhaust manifold bolts… The power steering system seems simple enough to do. I’ll definitely be changing that o-ring out, I know how much those can leak when they go bad. Thanks for the reply.
no, well..Sorta. when you refill the system you supposed to turn the steering wheel from left to right all the way. this gets any air out. Once your down to the cylinder heads and all accesories are removed you have the head bolts exhaust manifold bolts and anything connecting the cylinder heads to the block. dont forget to change that distributor plug O-ring.
thankyou
First I have to say great video, very well done. I have a 02 Grand Prix with an external head gasket leak I am going to tackle soon, I was wondering how many more steps is there to get them off after you get the intake out. I know I have to get all the head bolts out and I assume I have to take the water pump out too. One other question, is there any specific procedure when filling the power steering pump with fluid? Thanks again excellent video.
They are. The 3800’s are much easyer to work on, especially when doing a intake gasket set. The 3100s in the W body cars give alot of room to work in. Most GM cars with the 3000 series are not too bad to work with.
Mark, the engines are similar, But you need to make sure that engine is a non adjustable valve system like mine. It most likey is. But just make sure. those vans Ive never worked on, and I believe you have to take the wiper tray out to do this service
I believe all of the 3000 series are similar.
awesome video
good luck, its not that bad.. Take your time and be sure to mark the Fuel injector terminals. its a SFI engine and you must repalce each terminal from its original injector
official youtube hero! thanks for the tips. I need to tear down my 3.1
Is the step by step process the same for a 3.4L Oldsmobile Silhouette van?
I’m not sure where I went wrong… but now my car doesn’t want to start… started fine before I pulled the lower intake… now that i’ve done everything it won’t start… and it seems like the starter is whiney (not sure i’ve only started it once before this) could I have put the distributor in wrong? any advise would be awesome! the motor is turning over but it doesn’t sound right to me. I’ve checked all my connections and the plugs are all right.
What camera did you use for this video? And did you go to school for autos or are you self taught?
yea i drew out on a big piece of paper what injectors went where and cleaned them up.. took me forever to get them out of the bottom intake i couldnt get a good handle on them so what i ended up doing was take a small socket just big enough to punch them right out.. and into a piece of newspaper to catch them .. worked great really.
careful with the fuel injectors. thats a SFI motor ” sequential port” . you MUST put the original electrical terminals onto the original injectors. i almost screwed that up by not marking the wires. Ofcourse you dont see that on my video because it was a ” behind the scene” oops.. lol.. good luck on your job, let me know how it went man.
i guess i could understand that.. ive been doing it step by step except the tdc thing. all i have left to do is valve covers and fuel rail alt. PS. and top plenum…
right, Non adjustable Valve system. just tighten and go. I like to spin the motor so when the cylinder that im tightening the valves on is at top dead center with the cam lobe flat. its the way I was taught. Ive seen people have to tighten the valves over and over again cause something wasnt really tightened, valve clacking do do not tightening correctly etc. id rather TDC the cyl tighten and torque and be done, and never have to do it again.. my engine is quieter then most 3100 after this
the thing is you shouldnt have turned the engine over at all while tightening the rocker arm nuts..back to specs as the 3.1 and 3.4 you dont have to set the valves.
thanks after i drove it the knocking quit the problem i had was no power and that was due to fuel injectors apparently i cut one putting the fuel rail on the car runs great now thanks for the video was very helpful since you cant adjust i never had to spin the engine just torque the rocker arms to 25 foot pounds again thanks for the video
Nassau county.
Judd, Engine gets spun to your right. lets say your on the passenger side of your car leaning in. you want to spin it clockwise ” to your right”. now as far as knocking goes. do you mean bottom end knock or a tick?. judjing what you have explained, im willing to bet you have ticks.. multiple ones. follow thew video, setting these valves are easy. top dead center, and tighten exhaust and intake for that cylinder. No adjustements. tighten and torque to specs
I am pretty sure I have to have the intake manifold gasket on my 96 Cutlass Supreme. If you are up for doing the job I am interested. Where are you located on LI?
Gordon. Off the top of my head im not too sure about the major and minor differences. there could be. 1995 to 2005 is a long stretch. yes. they are known for quite a few issues.
I have a 2005 Pontiac Grand Am Se, with a 3.4L V6 – Aside from a few things in different places, like the orientation of the battery & the air intake filter box, are there really that many differences? I didn’t notice too many. One thing I will point out, is that these vehicles are known to have faulty fuel pressure regulators.
the car i was doing and still trying to figure out what i did wrong is a 2002 pontiac grand prix se 3100
i have followed your ways and i hear knocking im not sure if i set the valves wrong but if possible to get the exact way to turn the engine and set the valves that would be great
Excellent Video! Very detailed. Some people dont show correct Camera angle’s , go to fast, rush through it.They have done it before so things come second nature to them so dont explain it enough or show enough. You did a Excellent job. Thanks alot. If you have any other videos. My email is jrbbandit1979@yahoo.com. Please put in subject line” 3.1 intake video man”. Thanks again! Great Job!!!!
Depends on where you live. and the person doing it. I am in long island NY, a expensive place to live. and for this job I would charge about $360 for labor. a shop you have to remember half the engine is coming out. shops have overhead etc. I do not.. expect to pay anywhere between 400 and 900 dollars for this job. ive seen shops price this job out at about $1000 dollars. Its a big Job. lots of things to remove. if your guy is a backyard mechanic he should be able to work in a price like mine
I don’t have the garage, time, or tools to do this kind of work, but what kind of pricing should I expect from a shop? I have a go to guy who does great work and has pretty good pricing, but I know that this is going to cost a good amount and I want to make sure I am getting a good price.
Also, great video man. I sat here on my day off watching and learning. Thanks.
My father-in-law is the original owner and the papers are still in his name, so that’s a good thing I suppose… The problem with the multi function stick we got a quote for around $ 600 bucks + shop time. I was going to find one from the pick-a part place here, but to no avail yet.. I shall try e-Bay then, thanks for the tip. I will let you know about the class action lawsuit as soon as I find out more info.
2000 is way too steep. let me know if you get anywhere from that class action lawsuit. i think you had to be the original owner. multo function stick shouldnt be much money. go online ebay etc.. internet is your best friend for cheap shopping
Thanks for the response. We are in Canada and there was a class action law suit against GM CA. I am looking into it, maybe we are still entitled to some form of monetary help to get this thing fixed, because it is very unfair to fork out so much money for a faulty little plastic gasket. Wish us luck. As for the multifunction stick, it’s also a pricey part, and I don’t know if investing 2000 + into the Buick would be a wise decision…what do you think?
GreenEyes, the problem will worsen over time. you can try some additives to stop leaks. I personally have none to recommend, however, if you ever have a oil or transmission or even a power steering leak, try Lucus out. its a oil additive that actually stops leaks even slows down horrible leaks. At anyrate, the multifunction switch isnt hard to do, dont forget any tools you need places like autozone, o’riley they rent tools out now adays for the D.I.Y’er.. Do you want to sink money into it?
We have same problem with a 2002 Buick Century. It’s leaking coolant, nothing too serious yet. Got a quote from a local shop. $ 1200. That’s just too much to invest in a car that will probably continue having more issues as time goes by. We also have to replace the multifunction stick ( morons in Detroit designed it so badly, we don’t have lights). Now I am stuck being the new age Cinderella getting home before dark, or driving while pulling at it to get headlights. Will the leak worsen? advise
Yeah I’ve been think its injector related. Either clogged or failing. It’s a bitch of a cost to repair and doing it yourself is time consuming too.
That could actually be a computer problem, or a fuel injector getting ready to fail.. i had a fuel injector short the whole rail of injectors out and the car wouldnt run right. what your experiencing has happened to me with a buick century and a 1988 trans am GTA. The Century needed a Crank sensor the GTA needed a fuel injector
My 94 grand am has this same exact engine. But ive been having intermittent stalling problems for a few months. Running out of ideas as to what it could be but HEad gaskets were replaced 3 years ago, intake manifold gasket late 2012, basic tune ups here and there in late 2012 and early 2013, inc. map sensor replacement. STILL stalls intermittently. Sometimes it drives like a champ, then sometimes it barely wants to run at all.
thanks so much!
you most likey have your wires crossed. I see this alot with Do it yourselfers. get the firing order online. I think its 1,2,3,4,5,6 the three back cylinders are 1,3,5 .. and the three front cylinders are 2,4,6. also, as i said in my video YOU MUST put the fuel injection harness terminals on all the injectors each one came off of. this is a SFI motor Sequential fuel injecion.. start off there and let me know what you find
Thank you, great turorial, not boring at all , very helpful i am about to start working on my 2001 malibu next week so this was great preparation. is coolant in oil more often then not a manifold gasket issue or is head gaskets also a very possible problem, if i am not sure do you think i should go ahead and do the head gaskets at the same time? thanks for your help, Emil
Dude!! I did everything you did in your Tutorial and my Monte Carlo is missing real bad … any idea?
