    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.

    I noticed yesterday on my way home that the light for my odometer wasn't working. Is this an easy fix?
  • I have had a 2000 pontiac sunfire coupe for nearly a year now. It began giving me trouble from the time I bought it, which was all anticipated since it had over 150K. The panel cluster and for that matter ALL lights were not working within the car. I had to get the pontiac dealer to reprogram the computer and now the lights have been working ever since. However, not two months later, the transmission died-- not surprisingly, the auto place notified me that it was nothing but broken parts. 2 G's and perhaps 2 months later, I felt that there was still something wrong w/ the transmission but when I sent it to get fixed, they told me that the brake pads and spark plugs were bad so that they couldn't even check out the transmission until they were fixed. After this, I was getting thoroughly irritated and felt I'd just live with the grinding I experience from time to time. Since then, I've also had to get the heater core bypassed as it was leaking coolant some time over summer. The head gasket is leaking oil but not too bad that I'm losing any-- I just check it once or twice a week. Too, way too many issues to deal with. Now that is care and maintenance for ya.

    hi all ive got a 98 sun fire : with 164000 miles today i went to stop amd no brakes just a clicking sound i pumped the pedal a few times and they were back then my abs light cam on for a while then went out any ideas what i need to fix before this happens agin?????
  • There isn't the trans dip stick on a sunfire. You only have a oil dip stick.
    Oil is 5W-30, when you take a oil dip stick out- you will see in on the bottom.
    I put 10W-30 synthetic.
    Try Ebay for the owners manual.
  • If your sunfire is anything like mine (05), the oil pin is a nut underneath the car and you need a wrench to loosen it. The oil filter is in the most half assed place, between the radiator and the engine buried kinda far down in it. You'll need a 1" socket to get it off with many extentions, or hand held vice grips. Good luck!
  • Is the car actually overheating? Because my temp gauge is just straight broken.. it says my car is overheating, but I know better.. it's just the gauge reading stupidly
