#4255 of 4283 Re: 2001 Oldsmobile Aurora thermostat location?????? [ambercococleo] by e_net_rider Oct 26, 2009 (1:59 am)
Replying to: ambercococleo (Oct 25, 2009 3:30 pm) On the 4.0 it is at the rear of the engine, driver's side. The thermostat is in the block housing where the upper radiator hose goes. Two bolts, as I recall. The water pump is near there. Just follow the belt that is on that end of engine. One end is driven by the camshaft. There is a bracket/shield that needs removing to get at belt and idler/tensioner. You may as well check the condition of the belt and the idler pulley while there. You can replace just the pulley rather than the entire tensioner, and the bearing will go out at some time. Look for play in the bearing. Earlier models had the drain cock for the radiator hidden up inside the frame.
#4256 of 4283 DEX COOL by kpd2 Oct 26, 2009 (4:26 pm)
I have a 2001 V6, I've had it for 2 1/3 years and 35k miles (has 120k) and realized it has the standard green antifreeze not DEX COOL. I've had no problems with it while I've owned it   Does it matter?   Should I drain it and replace with DEX COOL?   Thanks   KPD Replies to this message: pscheid (Oct 28, 2009 3:12 am)

I lose power when its raining or very high humidity to the point the car going up hills crawls and backfires and i have to pull over and restart.the engine is hard to start in moist weather and at idle surges from 500 rpm to 1500 rpm constantly...is it the Mass Air Flow Sensor?

Replying to: kpd2 (Oct 26, 2009 4:26 pm) The issue with Dex Cool was that folks/mechanics claimed it was eating gaskets if my memory serves me correctly, and some switched to the green stuff like Prestone. The matter was "settled" and the Dex Cool was reformulated.    I brought this up with my experienced mechanic and he was aware of the issue.. He does not use Dex Cool.   You may want to Google Dex Cool for the details.

Replying to: airforce5 (Oct 27, 2009 6:35 am) More likely plug wires, a cracked plug, or cracked coil. Look back through forum for such issues when using non-GM parts.
#4260 of 4283 Rainwater Leak by 01aurora1 Oct 28, 2009 (6:37 pm)
I have a 2001 Aurora 3.5 that is leaking water into the floorboard of the driver's side back seat. I have blown compressed air through the drain tubes towards the front of the sun roof... and they appear to be clear. Are there any other "drains" from the sunroof????? The water is not dripping from the roof, as the tops of the seats and headliner are not wet. Could it be the seal around the back window???? The trunk appears to be dry.... but I do understand that water leaks can be hard to trace back. Any help would be very appreciated!!!!!
#4261 of 4283 Attempting to Remove my A/C Compressor by apboston85 Nov 03, 2009 (10:19 pm)
Recently my A/C compressor has been making a whining noise. The A/C in my car has not worked for about two years. I do not want my A/C compressor to seize on me and I don't have the money right now to buy a new or used one and pay for the installation. So, I am going to attempt to take out the Compressor and replace the serpentine belt with a shorter size.   Does anyone have any advice before I start this project sometime next week?   It is a 1998 Olds Aurora w/ V8.   Thanks in advance, Anthony Replies to this message: e_net_rider (Nov 04, 2009 4:12 am) pscheid (Nov 04, 2009 5:29 am)

Replying to: apboston85 (Nov 03, 2009 10:19 pm) My 96 had sensors for over and under pressure that would disengage clutch. So it seems odd that the clutch would be engaging when your system has not been working. Is the noise because the bearing is going out? What you are attempting to do sounds more of a headache than what it is worth. If the compressor is actually engaging, just remove the electrical plug. If it is the bearing you could have just the bearing replaced, maybe. But because you say it has not been working you might be wasting money on bearing if compressor is bad. The main question would be, "why was AC not working?" Was the problem because of blend doors or control head, or something to do with the freon circuit? That is, did the freon leak out, or possibly a blockage in system? Still, in either case I would say it is best to change the pump and leave the wires disconnected at the compressor. Often you are required to buy a new accumulator at the same time as compressor to get long term warranty. Just make sure you put the proper amount of oil in system. Leave system sealed until you are ready to finish repair, then disconnect at accumulator and pump, flush lines, reconnect and then finish charging. Or you could get the flush out of the way before installing new pump and accumulator. I would also check the orifice tube while it is apart. Replies to this message: pscheid (Nov 04, 2009 5:29 am)
#4263 of 4283 Re: Attempting to Remove my A/C Compressor [e_net_rider] by pscheid Nov 04, 2009 (5:29 am)
Replying to: e_net_rider (Nov 04, 2009 4:12 am) My belt idler pulley/ belt tensioner was making the racket, not the a/c compressor. Turned out the bearing in that was cooked. This was at 73K miles on a 1998 about 2.5 years ago. These parts plus the belt ran about $195.   The bearing in the a/c compressor had a lot of play in it at the time but was still functional.   enet knows more than I do about this stuff. But it is not an easy repair the way these items are packed so close to the right fender well and down in there.   Regarding disconnecting the wire to the a/c compressor. Wouldn't that isolate the noise problem between the idler assembly and the compressor? Also, there is a button on the center console by all of the hvac controls that says AC. It is lighted when the a/c is operating automatically and can be pressed to shut off the a/c compressor when you don't want it cycling on and off.
