So I was making my way Home from the GF's house and I noticed my SES light was on. I did get gas today which makes me think its just the cap. But after I got gas I drove around a bit too, Which makes me think its not. I pulled off the highway to see if anything happened if I restarted it. Nothing, but I did rev it up a few times and noticed that when the RPMs were coming down my Volt gauge went down significantly and my lights almost went out. The truck never died and held good power (+14V) all the way home. Since new(to me) the truck always had a rattle/hissy sound that did seem to be a little more noticeable but it coulda just been paranoid ole me. I do need an oil change too!(200km ago)

Just wondering if theres anything I can do, other than take the gas cap off and re-fit it properly, to not have to go to PartSource and get the codes read?

Thanks,

Brad.

 

Take to to Advance Auto or Autozone and they'll read the code for you for free. I bought and OBD2 reader on ebay for $35. It's great. Not only gives me the codes but resets the light. Good luck!

 

without reading your code, you can't pin pint what would be wrong with her

get her read, it will ease your mind at least...

 

I need a thermostat, STAT! lol Well i went and had her read and it was a bad thermostat, so I purchased one for $14 and am gonna have to wait till weds to put it in. I don't know if the guy erased the code or not but it wasn't there on the drive home. How hards the job?

 

Very easy to replace the tstat. Shouldn't take more than 15-20 minutes. Just make sure the old seal comes out with the old tstat.

 

Perfect, will I need a lot of antifreeze?

 

yar x2 on the seal.
put a rag or something down in the tube and scrape the old crap clean, and for F**Ks sake, do it when the engine is COLD

this could be a good time to jump on one of the dex-cool threads and blame the old tstat on it
