Coolant Leaking problems of the 2002 Chevrolet Impala

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.

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.

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.

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.
