Five problems related to coolant leaking have been reported for the 1999 Oldsmobile Alero. The most recently reported issues are listed below.
I own a 1999 Oldsmobile Alero with a 3. 4l engine. At a cost of $652. 01, on 28-October-2003 I had service performed on my vehicle because I was loosing coolant at regular intervals and it was not leaking onto the ground. The severe cause for concern was after I had refilled my coolant reservoir, drove approximately 3 miles, and all of the coolant was gone. The temperature guage shot up to the red zone, and I pulled over immediately. I had the car towed to the dealer and they indicated that this was a common problem for vehicles with this engine. They replaced the intake gasket and I was on my way. A few weeks later I noticed the coolant level was low again, and I had to add more coolant. I took the car back to the dealership on 25-November-2003. They checked the car and said they could find no leaks. I continued to drive the car. Consistently, every 2 weeks, I was refilling the coolant resevoir. This has been happening until recently (February 2004). In late February 2004 I started losing coolant at a much faster rate, about 3 day intervals. On 2-March-2004 my car did not start the first 2 times I tried, on the third it caught. I decided to inspect the oil, using the dip stick, and found that the oil was a thick goo. This prompted me to call gm and the dealership to identify my options for having this problem resolved. I am frustrated, aggrevated, annoyed, among other things, and I fear that had this gone undetected, the oil would have gotten to a state where it would not have allowed the engine to function, perhaps leading to an accident. Not only do I fear for my safety, but I am concerned that having a severe problem like this "fixed" only to find that it happens again will only lead to the samething happening yet another time. How many times will I have to have this problem fixed? is this a recurring safety concern?.
Purchased the car in February'03. Bad vibration when driving at speeds over 45 mph, tires rotated and balanced 4+ times, both front wheel bearing/hub kits replaced in less than 6 months after purchase, still occurs and have just grown accustomed to the shaking. Engine coolant leaks: replaced pump and "o" ring. Power steering pump and return hose replaced. Driver side window does not roll back up(believe dealership replaced prio to purchase). Driver side mirror motor has never worked properly, dealer(in rochester) put on receipt of last repair that they replaced motor, but didn't actually have part, but was on order. Never received a phone call back when or if part came in(dealership is over 300 miles from my home, purchased car on the internet).
1999 Alero 3400 sfi engine w/39186 miles. Low coolant light comes on. Pontiac delaership says lower intake gasket leaking. Orange antifreeze dexcool getting into engine oil. Oil looks like coffee w/creamer. Car not driven since 12/02/2002 due to olds dealer closing doors after 36 years and unable to get them to honor the extended warranty I purchased thru them. Bbb and state atty general's off ice of no to help to locate/have them honor warranty. Pretty much they ran off w/my $.
Upper or lower intake gasket leak. Seems to be a very common problem with the 3. 4l v-6. Noticed coolant loss with only 30,000 miles!!!!.
Engine gaskets failed, which caused coolant to leak into the oil.
