Pontiac Sunfire Care and Maintenance

Hello everybody I could use a bit of help here. I'm trying to change my oil and can't find the drain pin on a 96 Sunfire 4 door auto with 4.2L motor. Normaly id just take it to a shop but I'm in Switzerland and was charged around $19.00 for a Wix oil filter. so i know better than to take it to a shop. Aside from asking no less than 150Chf then they are going to hit me with the American car factor just like Americans like to do to European car owners except its much worse here. Unlike in America, the Europeans really don't have the parts in large abundance for GM cars.

    you have a sunfire with a 4.2???? how???
  • Hello
    I have a 02 Sunfire SLX. I have found the fuel filter under the back of the car and it looks to me like its the original. I can access it just fine without lifting the car up but I'm a bit confused about how to disconnect it. I have the Haynes book and I have the just of it BUT looking at it I see the two nuts. I can't decide which one should turn and which should be held stationary.
    Is the filter supposed to spin while I hold a wrench on the line to keep it from twisting?
    Also what are my options if it doesnt want to budge? I have very little space to get a wrench in there and if the filter is supposed to twist theres not much room to do this by hand either.
    Now I can make more space but theres some black box with hoses running into it. I have no idea what this thing is but it looks like one bolt will take it down.
    Any tips would be great!
  • I have a 98 Sunfire/2.4 motor
    There is no flow to or from the radiator...
    I've already done the following....
    replaced thermostat
    replaced water pump
    radiator rod out
    block check for combustion gases
    still.....nothing... anybody know about this car...?
  • Had the thermostat changed about 8 months ago and now the car never gets over 50- 55 degrees. Any suggestions? Rad is good. Thanks
  • I'm having a similar problem, I have had three new thermostats in the last week, yeah I do mean week. Each time I get great heat at first and I think we might be done, then it suddenly stops having heat. I live in ohio with zero degree weather right now and a two year old child with me. Now today my car suddenly has no heat BUT the engine is overheating. Can someone pleeeeze help me before I take a baseball batt to this car. Its supposed to last me untill I graduate from college and I really want it to. :sick:
  • My car is not over heating. I just can't get any heat over 55 degrees. Can you possibly put the thermostat in backwards? The garage put mine in. Where is the thermostat? On the top of the motor, at the top rad hose that goes into the block?
  • Have you had your system flushed? Sounds like you have a blockage somewhere. Is the thermostat on the top of the block at the top rad hose? I am going to try another thermostat. Might have a faulty one..Thanks

    What are the steps in changing the water pump and thermostat? How difficult was it and how much time did it take? Thanks ;)

    I know how to do and oil change and all that good stuff. Here is the issue. 1) Can't find the oil filter; 2) Can't find the drain plug (I mean come on, the drain plug!!!); 3) I have never change an oil filter like this before. It is just a filter, like an air filter??? Any info is greatly appreciated. Thank you.

  • I agree with BMohr, never seen such an odd setup for oil changes. '04 Sunfire, first time working on a GM product. The filter is a small element type, but HOW do you install it? It looks like it goes into a cast-on piece located just under the air-intake pipe leading to the air cleaner housing. A mechanic told me there is a bolt that runs through it that has to be removed, but this one seems to be a sort of rubber or neoprene cap that might fit a large filter wrench. Grrrrrr has GM not heard of spin-on filters? Am I on the right track or should I look somewhere else? Any help is appreciated!

    Hi, I'm new here, not sure how to start a new discussion for my question.

    I just replaced the spark plugs in my Sunfire. I used NGKs instead of ACDelcos. Is that OK? I read somewhere that in some GM cars, one MUST use ACDelco plugs because the computer is tuned to the electrical resistance of ACDelcos, and that using another brand like NGKs will throw the efficiency off and cause bad gas mileage. Is that true of the 01 Sunfire 2.2?

    I noticed the NGKs are gapped at .050 and the ACDelcos are .040 (I left the NGK at .05 per their specs). Is that an indicator that it's not a good match for my car?

    Since I just replaced the plugs I haven't had a chance to measure my MPG, but I wonder if I should just dump the NGKs and get ACDelcos.
  • friend's got a 99 sunfire with the 2.4 and 96,051 miles. it sometimes feels like im towing something when i drove it. when in part, the idle seems tensed if that makes sense, and when you rev it hesitates or something like that. hard to explain. when going it sometimes felt sluggish and engine sounded a bit odd.
    there is also a pop when turning the wheel right or let, like turning around a corner.
    any ideas would be GREATLY appreciated.
  • the only problem i'm having that when its hot outside my car gets heat but when its cold the heat works but no heat blows out. I know its not the thermostat someone said it could be something call the vacumn is that right
  • Did you ever find out what was wrong with your sunfire? I am having the exact same problem right now with mine. We have replaced the Water pump, the thermostat and now the head gasket and we are having the exact same problem still.... PLEASE HELP! :lemon:

    I have a 96 pontiac sunfire 2.2. We have replaced the thermostat, water pump, and done a radiator flush. My temp gauge keeps going through the roof, (but only sometimes) and some of the guys at work suggested that it could be a sensor. I am not loosing any coolant, and I have heat. The only other thing I can think of is the head gasket, but hope to find a cheaper solution... does anyone know anything about this sensor possibility? Thanks a bunch
  • Hi, I have a 96 sunfire 2.4L. I have a leaking fuel injector. The car has 265K miles and was wondering how hard it is to change the injector myself. Has anyone done this that could offer some steps?
  • do you need special tools to remove the control arm bushings??

  • sounds like your coolant level is low
  • Does anyone have a list of services that will be performed for a 72, 000 mile maintenance on
    a 2004 pontiac sunfire?
    Can anyone suggest a website to view that shows services that will be performed for a 72,000 mile maintenance?
    Thank you for your help.

    Hi All, I have a coolant dripping right by the floor panel on the drivers side. (I believe the heating coil is located behind the firewall on this side.) When looking from underneath the car, I don't see any visible hoses or lines that the leak is coming from. Any ideas? If it is the heater coil, how easy is it to replace. Thanks :cry:

    I had the same problem. My car was always over heating, even while I was going short distances. I discovered by trial and error that if I turn my cabin fans off on my 97 Sunfire wouldn't over heat anymore.

    Don't ask me why it works. Everyone tells me it’s the opposite of what should happen. I have a feeling it’s because air is being drawn away from the engine and over it when the vents are open and pulling air through. Respond back if it works, thanks.

    I found out what was the problem. One of the heater hose clamps connected to the heater core was lose. I tightened it and so far, no more leaks.

    I had the same issue with my '96 Sunfire earlier this year. I replace the sensor, and the problem went away. Im pretty sure there are two sensors, I got mine from my local Pontiac dealer.
  • need to find out where to locate the coolant temp sensor
