Re: Attempting to Remove my A/C Compressor [e_net_rider] by pscheid

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.

1998 Aurora idiosyncrasy by jhowdy

Live in Florida, bought the car used in 2005 with about 50,000 miles, great shape inside and out. Once the weather turned cold enough for a heater I noticed that occassionally the car would just stop running while sitting at a red light. It started right up again and didn't show anything in the information center. It still does it now and then.

1998 Aurora Information Center Lighting Disappears by jhowdy

I drive two vehicles changing out between the 1998 Aurora and a 1996 Lumina. I had been driving the Lumina for awhile and changed back to the Aurora driving at night when it started raining and I reached to the left for the windshield wipers and messed with the Aurora dimmer switch/cruised control instead, then realized my error. Upon returning home, I turned the car off and went inside, next day the battery was dead, seems while trying to turn on the wipers, I turned something on that drained the battery, anyways the battery was dead. It was fully recharged and the car starts up as always, however since then the information center lighting, the radio lighting, and other center dash lights, radio lights, thermostat light, a/c-heater light intermittently just disappear or don't light up when the car starts. Now, another oddity since that time and it didn't start happening immediately after the dead battery episode but, I started to hear an chattering, arcing sound from the left side of the dash and I think it was coming from the dimmer/cruise, once I turned off the cruise at the switch, it stopped. A day or so later I stood in the yard with the dog early in the morning and the parking lights on the car flashed on and then went off again several times, I feared the battery would be dead again but the car started right up as always. The cables were removed completely from the battery in an effort to reset it if you will and it seemed to work for a short time, the dash lights came on and stayed on when they should have, the arcing sound was gone for a week or two then it started all over again with the exception of the flashing parking lights. Ideas or educated guesses?!

1998 Aurora Antifreeze leaking by jhowdy

Another problem with it! I drove it a few miles one night and noticed the temperature was rising, I turned off the a/c, parked and turned it off. The windows fogged up, the temp kept rising. I was able to drive it home and park it. Next morning checked the antifreeze and it was not at the cold line, added some antifreeze and its been fine for a couple of weeks. Today driving in heavy stop and go traffic I noticed the temp rising again, turned off the air while sitting and on while moving, got home and smelled antifreeze. It's dripping front and center about a foot back from the hood latch. Suggestions?

I have a friend who also had a 1998 Aurora with the V8. He also had some of the same symptoms. Turned out to be "Crankshaft Position Sensor"... I think it maybe is even a factory recall. I also had to replace the same part on my 2001 V6... but not a recall. It just manifested itself as an engine missfire for me.
Hope this helps!!!

Check out the easy stuff first. Radiator, clamps, and hoses. Water pump. Thermostat. The air dam under the front fascia. Fresh coolant. A properly functioning radiator cap. And if I am not mistaken, isn't there an auxiliary electric cooling fan to assist the radiator fan when the temperatures exceed 220?
 
When the car is hot and it is dark, and with the engine running, take a flashlight and see if you can locate exactly what the source of the steam is. If you are fortunate, you may have a leaky radiator, a bad thermostat, or a failing water pump issue. I had both the radiator and the water pump issues at the same time a year ago about now. I have a 1998 Autobahn with 111K.
 
The location you mentioned, about 12 inched behind the hood latch......
 
Well as you are facing the engine in the dark and using your flashlight, you might want to look over to your left (car's right side) under the radiator shroud to see if either the top radiator neck is the source due to a failing hose, a loose hose clamp, or a leak in the radiator at the top neck (common). The leak may be running across the top of the radiator to the center as you described, 12 inches behind the latch.
 
The water pump is up front too, but off to the right of center as you are facing the engine. Mine was still functioning but was seeping, and you could see steam from that as well as the wetness. By the way, how old is your thermostat? Is it functioning correctly or stuck intermittently? That is right there with the water pump.
 
Some guys are missing the rubber air dam under the front fascia. Since there is no grill on the car, this air dam is the only thing forcing cooler air up into the engine compartment and assisting the radiator in the cooling process.
 
Good luck. Let us know how you make out.

The symptom you describe is consistent with a leaking fuel pressure regulator. I have replaced 3 in my '97 with 170,000 miles. The part costs about $50 (buy nothing but AC Delco) and takes ~10 minutes to replace. If I am right, outside temp was merely a coincidence.

Fuel Pump by pscheid

Gave up the ghost at 111,000 miles on my 1998 with no warning. Worse, it happened at 11 PM on an interstate 25 miles from home with the wife and the dog in the car. Not good.
 
Further, the metal fuel pump mounting ring on the top of the plastic gas tank was 80% gonzo, requiring a new tank (drop rear suspension). The repair guy showed me the old tank and pump, and the old fuel pump was essentially attached to virtually nothing.
 
The good news is that the pump assembly includes a new fuel gauge sender, so now the fuel gauge works properly. The better news is that the check engine light throwing a fuel evaporation code has been resolved with this fix, and the car will pass emissions. And the raw gas fumes I very recently started to get on a full tank, also gone.
 
Wife bugging me to get rid of the car....... My exceptional economic analysis of the benefits of the repairs versus vehicle replacement is falling on deaf ears.
 
Apparently to her the dog's safety trumps my argument.

You poor dude. We had the alternator go out on our 2001 without warning about 2 blocks away from the shop. The city was working on the road we was on and had to detour but didn't have enough power to get there. Husband is still recovering from 2 total hip replacements and I had just gotten cortisone injections in foot. Had given kids only cell phone to take to college that day in case they broke down in shitty car. I knocked on every house but no one home and just happen to come across woman talking on phone in yard. Mechanic started looking at it and said just about whole front end has to come off just to get to alternator. Under the radiator area. Who were the genuises who thought of that design. It's like they want to piss of every shade tree mechanic around. And the alternator was almost $320! even a rebuilt one was only $30-40 less. Love the car but hate
