#17 of 46 Re: 1996 Buick Pk. Ave. Engine Problem [imidazol97] by joshlin1932 Nov 04, 2007 (9:32 am)
Replying to: imidazol97 (Nov 04, 2007 7:43 am) I didn't think the heating thing could be relative to this problem because it ran for a couple of weeks and about 1000 miles after the water pump thing. Most of that was highway driving and it did not heat up.   Also, it was not hot when I shut the engine down. I had only driven it about 300 feet to get it into the garage out of some bad weather we were expecting.   I have seen some mysterious things, but never anything like this. Thanks for your help anyway.
#18 of 46 Change oil soon light ON by mivada Nov 05, 2007 (2:44 pm)
I have a 95 Park Ave with 130K miles. A few months ago when driving the car, the change oil soon light came on for a few second and the car behaved weird, it wouldn't go smooth but almost like stop-and-go, stop-and-go kind of thing. I have changed the oil twice since then, as well as the battery and it still shows the same problem. The change oil soon light comes for a few second, the car starts doing the stop and go run and then it keeps on running ok. Does anyone have any suggestion what that may be?

#20 of 46 92 park ave, losing oil by krandike Jan 28, 2008 (5:05 pm)
I have a 1992 park ave with a 3.8l in it. It used approximately 1qt between changes until a recent trip. While on the trip it started losing oil at a rate of about 1qt per 100 miles. It does not smoke, the oil pan is tight, and I looked in the radiator but the coolant looks to be in good condition. I am looking for possible causes for this and I thank you in advance for any help.

Replying to: mivada (Nov 05, 2007 2:44 pm) The first thing I'd check is my battery connections. Turn off all accessories. Turn AC unit to off.   remove negative battery cable and check for corrosion. Remove positive cables and if you have the double cable-one on top of the other check between them. Some people recommend slicing into the plastic covering below the connector to look at the copper cable. Funny problems happen when one of those cables doesn't make a good connection.   A move remote place might be the ground buss which is inside the car and some functions from the dash ground through it. Are you a in a wet climate where salt and snow and lots of moisture track into the car and the carpet stays wet?
#22 of 46 coolant by jrackley Mar 15, 2008 (4:20 pm)
i have 98 park avenue. my thermostate stuck. took guts out. put regular water in radiator to get it home. changed thermostate and drove it down the road temp gauge got to 207 degrees that was as high as it got. it cut off and would not crank back up. changed battery. it started but when i cut it back off it had hard time starting again. I drained water and put 50/50 mixture of dex-cool and water.But now it sounds like rod is knocking did just the water cause that much of a problem Replies to this message: imidazol97 (Mar 16, 2008 12:12 pm)
#23 of 46 engine noise by jrackley Mar 15, 2008 (4:24 pm)
it is making a horrible noise do you think it messed up the bearing on the crankshaft.

Replying to: jrackley (Mar 15, 2008 4:20 pm) Running hot you may have damaged a head gasket or head. Look at the dip stick to see if the oil shows a milky color like a chocolate shake? If so you have coolant in the oil and that is poison to bearings. It deteriorates them fast chemically.   You are going to have to find out what's happening. I suppose it's possible the intake manifold just decided to leak at the time of overheating. And that can put coolant into the cylinders and oil.   If you have a knocking, your motor may be past tense already--not to scare you too much.
#25 of 46 adding coolant by icemanstone Mar 17, 2008 (6:44 am)
Actually I have a two part question. The first is I bought my 96 park ave ultra used with about 125,000 mi. I have had to add coolant to the overflow container three times in the five months since I bought the car. In total it comes to about two and a half gallons of coolant. I have never seen this in any car I have ever owned. the second issue I have is on cold mornings the transmission is very sluggish even after letting the vehicle warm up for approximately ten minutes.I have had the transmission flushed and refilled. If I shut the engine off and wait a couple of minutes then restart the engine it runs normally. Any ideas what is going on?
#26 of 46 2001 Park Avenue Suddenly DOA - Won't start; not battery; not fuses; help? by jonif Mar 20, 2008 (10:00 am)
I have a 2001 Park Avenue Sedan, 3800 Series II V6, Transmission 4 speed electronic. with Prestige Option Package. One owner, about 54,000 miles. Transmission failed/replaced under warranty at 26K. No other problems. I drove it into the driveway last night after running errands for about an hour. Went out to pull in the garage and it will not start. One click I heard. Then nothing. Gauges were moving without key in it! Battery dead overnight. Recharged. Checked all 4 fuse boxes. Tried starting with and without battery charger on it; and bypassed battery; still just a click and then the car is DEAD. Have tried both key fobs; neither will start it. Was running FINE before this. Have read all forum posts, but don't see a fix. Any ideas? As the seat was returning to memory position it just stopped and the car would not start. Could it be a short somewhere? Totally mystified. Want to avoid towing it to a dealer if possible. No lights inside and I know of no way to check codes. It won't jump start either.
