#13340 of 13621 Wooshing/clunking
Apr 27, 2007 (11:57 pm)
I have a 2005 Chevy Impala with 55,000 miles on. When I start it cold, or often when I step on the gas and am pulling away from a stop sign or stop light, I hear a noise that sounds like water wooshing/clunking around under the hood. Best I can describe it. My have the extened warrenty until 75K miles. However, and of course, everytime I take to the dealership they havent been able to hear it. My wife and my mom comment on it all the time when we are driving. What could this be? Maybe I can point the dealer in the right direction.

I'd guess air in your engine coolant system; if it's been changed recently that'd be my first thing to look at.

Anybody have any advice for removing the plug wires on the firewall side of a 3.8l Impala? I removed the top engine mounts and tipped the engine forward which helped access, but I can't get the old wires off those back plugs. Bought a tool for that purpose, but even if I can get it on the wire boot I don't have enough clearance to actually use the tool.
Because the Halo plugs say you have to do them all at once, I figured I'd tackle the back side first (since this is my daily driver, and I don't want to get stranded). I'm sure I could get rough with the existing wires and force them off, but I'd rather not have to replace the wires too if I can help it.

I would also tend to think that it is related to the coolant. My '04 does it and has done since new. I have never taken it in to have it checked out, but I don't think it's a major deal. But I do think it is air in the cooling system that could be aleviated by have the system purged??

Mike, the wooshing sound could be the coolant level being too low. Add 50/50 Dexcool mix to your overflow reservoir and see if that helps. There are also 2 air bleed screws on topp of the engine that may help get the air out of your system (I'm assuming you have the 3.4).

BTW my 2004 Impala 3.4 made the sound when I first bought it about 2 months ago. I drained and refilled the coolant since it was 3 years old and never heard the sound again.

I have never done that on an Impala but I can tell you from experience on the Buick Le Sabre with the same engine that the easist method doesn't sound that way if it's something you've never done however here it is.
Put a floor jack with a block oif wood under the engine (not under the oil pan)
Jack it up just to where you can tell you've put a little upwards pressure on the egine.
Remove the bolts in the front two engine mounts.
VERY SLOWLY, lower the jack. As you do this the engine will roll forward and down making the rear spark plugs move to an upward facing position once they get to a point where you feel you can reach them lock the jack and take care of the plugs.
Have fun. By the way as a note on all vehicles if something is in the way of what you're getting to and its removable in the long run you're better off to remove it than work around it.

sounds like this is an recurring issue. Mine is also an '04 with the 3.4. Not a serious issue, but could be annoying listening to that sound of gurgling water. Sounds like flushing the toilet in the car. ...
Maybe I'll try changing out the coolant or locating those bleed valves.
#13348 of 13621 2003 Impala 3.4L woes
May 01, 2007 (5:53 pm)
This car was purchased from a dealer from a fleet with about 16,000 miles on it. Has been maintained with oil changes as per manual. It has been using about 4-5 quarts of oil between changes lately. Took it to shop today and was recommended to part with it. One plug was coated in oil and the radiator is full of sludge. The car has 112,000 miles on it and obviously the engine is in for a major overhaul. Is this typical of these engines? btw, all the miles have been highway miles. also, the owner's manual recommends coolant change at 150,000 miles, but this has majorly broken down.

My 2001 LS has the dual temp control. The drivers side bulb on the temp slide has burnt out. Does anyone know if this is a actual bulb or a LED?
