Coolant Leaking Problems of Chevrolet Impala

This coolant crossover pipe gasket leak has been a repeated and multiple vehicle problem with the 3. 9l and 3. 5l and gm only came up with 2 technical service bulletins; the last one was #07-06-02-006e: coolant leaking from engine (replace coolant crossover pipe gaskets) - (Mar 5, 2012). However, the new gasket design presumably repaired the leak. However, it did not. I have seen this issue discussed on several web sites with all complaining about the same unresolved issue. My 2008 Impala with the 3. 9l v-6 has been repaired for this issue on the following dates, each time I was assured it was satisfactorily repaired: 02/09/2019 � diy due to dealership cost. Repaired per gm TSB/gm technical service manual. 11/30/2016 � dealership. 03/10/2014 � dealership. 01/11/2013 � dealership. And now, it's leaking again! I chatted with Chevrolet online on 10 Apr 2020 and cecil said that warranty had repaired it once, but the issue has been and still continues. Gm would no longer repair the leak. This is what I was told: cecil at 15:40, Apr 10, 2020: unfortunately, once the decision is final that it cannot be changed anymore. But here is what we suggest, you can take the vehicle to a certified gm dealership about this to have it diagnosed and it might the same symptom but different root cause. We cannot perform diagnosis over chat. Cecil at 15:41, Apr and for assistance, I highly suggest that you speak with the customer experience manager or cem at the dealership. However, the dealership is the one who told me that it could no longer be covered under warranty! this issue is something gm should have long resolved with a better solution. This leak is a continual problem and gm doesn't offer any better repair options and will not repair the leak again.

Supposedly the cooling system was fixed in 2003 but it still tells me that my coolant is low and it leaks. I am the second owner of this car and have only had it since September of 2019. Also the transmission has a delayed shift from 1st to second.

Bought 2007 Impala year ago lately getting a smell of antifreeze around pass side frt check for leaks nothing found not down on coolant and getting heat any suggestions on this.

5/1, 5/2--ignition simply clicked . It took several minutes to get it started in each case. Took to repair shop--could not find the problem. Not the battery. 5/6, 5/8--engine died while I was driving down the road. Ignition clicked when tried to restart. Taken to repair shop again--could not find the problem. Chronic--since I have had the auto the "low coolant light" shows. This last time at repair shop, I was told that auto was leaking coolant--most likely gasket and would be very expensive to repair.

About 1 year ago my 2003 Impalas heat gauge started acting funny like the car was overheating but then it would go back to normal. It was cool out about that time of year and I also noticed the car had no heat. I replaced the thermostat thinking that was the problem but it did not help and the problem persisted. My husband then noticed that the coolant level was low and added more. That also did not fix the problem, and about a week later we noticed the coolant was low again. We looked for the leak and could not find one. I finally took the car to the dealership and they automatically knew what the problem was and stated it was a problem with the 3400 series engine. We paid nearly $700 to have the car fixed. I have recently noticed that my coolant level again is low but can not detect any of the same problems as before, I still have heat and a/c and the heat gauge is not fluctuating but I have been looking around at recalls some forums about the same type of car and have discovered many others are having the same trouble, but there is no recall for the 3400 series motor as there is for the 3800.

Had intake gasket replaced in Feb. Of 2006 for coolant leaking into engine oil, because of said gasket failing (77,000 approx. Mi. ) noticed coolant level dropping again in Jan. 2007 (85,000 mi. ) found white/brown sludge in oil again!apparently the problem is back and I am told it will keep coming back until gm corp. Comes up with a permanent fix. Why are they not concerned about this? I can't afford to keep on fixing this problem that has no end in sight. I like my car but if gm won't address obvious design flaws I'll have to buy from somebody else.

- the contact took the 2004 Chevrolet Impala in to have a routine oil change. The vehicle had 37, 792 miles. The contact was told by the dealer that the coolant & oil was leaking into the engine. The vehicle was repaired and she has the repair order. This is the first incident. The vehicle did not give any warnings. However, the contact's coolant light turned on 9/06 and she had coolant added.

There is a huge amount of oil in the coolant in my 2001 chevy Impala. Knowing just a little about internal combustion engines probably an intake gasket leaking. For a car which has been very well maintained with under 80,000 miles on the odometer this was alarming. High engine temp and a sludge in my motor are the obvious consequences. Who knows what the long term affects will be. The car is now at the mechanics and already I am looking at 700 to 1,000 dollars which I do not have to repair.

At 89,000 miles I noticed that my engine coolant light was on. I filled the coolant. The light continued to come on and I filled it a few more times, but could not pinpoint the leak. Then one night the engine started to make noises and I pulled off the road to check the coolant. I filled it and waited until the car cooled. I started the engine and drove about a quarter mile and the car shut down. When I towed it to a garage I learned that the head gaskets were leaking water into the engine. The engine had to be replaced. Since the warranty expired I paid the garage to put in a used motor. It cost me over $1300. I never thought to contact chevy since the warranty expired. Now, because of my internet research, I know this is a common problem. Unfortunately for me I also bought a second chevy in 2002. Wouldn't you know it - my 2002 chevy malibu had the same symptoms at 62,000 miles. I was lucky enough to get by with replacing the head gasket. The same garage gave me a price break and fixed it for $252. 00. Boo to chevy.

Complaints of engine temperature always ended with no found problems on vehicle owned and serviced regularly since purchased new in April 2003. Regular oil changes and engine coolant flush as recommended by manufacturer were completed and still no problems found. At 75,671 miles dealer found intake gaskets leaking and said engine damage would occur if not replaced. Repair cost $658. Found that technical service bulletins indicate this is a know problem in a host of gm vehicles from 2000. Public is being forced to pay for major engine repairs for poor engineering on the part of the manufacturer. Engine failure due to this problem could result in serious accident for the less than knowledgeable driver. Environmental concerns with poor less than optimal engine performance, loss of coolant, oil, etc. Should also be considered. How many of these repairs have been done over the span of years by the manufacturer? how many uninformed consumers have been duped by this lack of manufacturer responsibility?.

Took vehicle in to dealer for regular maintenance, told that lower intake gasket was leaking bad and needs immediate replacement as well as coolant flush. Total for repair is $1450. Vehicle has only 83k miles.

Leak of coolant, low coolant light.

My 2002 Chevrolet Impala suffered a breakdown of the antifreeze that turned into a thick brown substance. This caused the vehicle to overheat and gm did have the coolant flushed. Two weeks later the lifter began to rattle when the vehicle was first started. When I took the vehicle back to the dealer, I was told that a seal was leaking coolant into the oil. I was assurred that this was not related to the original problem and was not covered. The repairs will cost over 760. 00. I called gm customer service and after waiting all day, the response was that the service manager was not there, but the problem could not have been caused by the first problem. The coolant turned into a thick brown gritty substance that would have been like sandpaper going through the engine and they claim that it could not have caused the seal to fail. It is obvious that general motors refuses to stand up for obvious failure and defective equipment. They refuse to stand up for the repairs. This coolant according to gm is supposed to last at least 100,000 miles and it does hold up as they state. They should admit the problem and make the proper repairs to customers vehicles.

At just under 60,000 miles, low coolant light comes on. Dealer says it's leaking coolant at 2 places: at lower intake and at water pump. Cost to repair: $600 to $850, depending on repair facility. If there was a recall on this, I did not receive.

The recall remedy for the upper/lower intake co303-4 manufacturer # is a short term fix, and is not correcting the problem. If a sealant was used to stop the leakage into the coolant system to the vehicles motor it did not fix the problem. Also it could move around and flow to other places at anytime there was a temperature change.
