'03 Chevy Impala Problems

[RadarRider]

My girlfriend's got an '03 Chevy Impala & she's been having all sorts of different cooling system issues. Recently, the car had overheated & the car was brought to some quack that just replaced the waterpump & filled it back with green(instead of Dex-Cool)anti-freeze. A couple of days ago, it was running really hot on her & she had to leave it @ work. Today, I went down there to have a look @ it & I noticed one of the purge fittings that you're supposed to "burp" the system with after refilling the cooling system was snapped off. I know these fittings MUST be opened when burping the system & if they're not, the cooling fans don't kick on & there's no heat(which is what's been happening all along). I've tried to look up these fittings online & can't find them. Does anyone know what they're called and/or where to get them besides a dealership if possible? Also; does anyone know the 100% correct way to purge the cooling system with these fittings open? I know there's gotta be someone on the .Org who has a wife, son, or daughter that owns one of these inferior machines! Can anyone help?

Hmmmmm? Just had my wife's 01 Impala's intake gasket leak fixed. Never heard of these burpers before? I'll look around and let you know if I find anything. Good luck.

Thanks, Hank! I appreciate you looking for me! I had never heard of these burpers either until I had worked @ an oil change & tune up place(you know---the places that change your oil & then try to sell you a bunch of other crap like airfilters, tune-ups, etc.). If I remember correctly, you need these bleeders open while burping the system or it doesn't purge correctly & you get these issues. All I can say, Hank: I HATE GMs!!!

You got that right! I have too many of them in my driveway too. I have my late parents '98 pickup and '01 Impala and my son has a '97 Tahoe. Vortec engines are crap! Looking forward to getting all of them out of my sight. I hate 'em too!

I know you're serious, but you've got a funny friggin' way with words! I hear ya on all counts!

I think the way to use the burp ports, is to open them with the car running and let it get up to operating temp and let em burp coolant until there is no more air bubbles coming out. I would assume you leave the pressure cap on to force all air out. Those valves should be higher than anyother opening on the cooling system i think. That way the air goes to the highest point to escape. If i am wrong someone please correct me. I don't work on GM's that much (anymore). Like Hank said too, they are known for the intakes to leak. THere was a recall for them. It might have something to do with your overheating. Watch the oil very close. My neighbor destroyed his 97 3100 in his grand am by allowing the intake to leak and fill the crank with coolant.

Close but no cigar. Wrong years? Does have how-to instructions though.

Looks like some help toward the bottom of this thread?
