Dexcool antifreeze deteriorated my intake gaskets of my 99 chevy venture, sludged up my engine and caused my car to overheat and leak dexcool continuously. The dealer just told me sorry but it will be about 1500 to 2000 to repair. That antifreeze was supposed to be never changed and work until 150k miles. My van is a leaking reliability problem that could strand us on the road because of the dex cool they put in the factory. There will be a recall if you investigate this. The problem is all over the web and there is a class action suit about it in california. It affects hundreds of thousands of people.

Experienced coolant leak into engine. Personal mechanic found that dex-cool had caused excessive corrosion to intake manifold and that gasket had to be replaced. Spent in excess of $500 to repair this. Other people I know say that if the corrosion was bad enough that the cam shaft might break. I am not willing to put my family's lives in jeopardy with an issue that gm is aware of. The fact thta nobody has died from this is no excuse not to recall the gm 3.4l engine vehicles to repair this problem at no cost to the consumer. Also, the effectiveness of dex-cool needs to be re-evaluated with regards to performance and the affect on engine parts long-term.

I bought a used 1999 chevrolet venture with 54,500 miles on it. 7 months and 32,000 miles later, the van is at my local chevrolet dealer with $1,650 $2,200 of engine damage, due to an intake manifold gasket failure.*ak the vans 3.4l engine was well-maintained, with frequent oil changes and inspections. The only warning sign that I got was that the coolant level had to be topped off about once a month. A mechanic said that the coolant loss was due to evaporation. My mechanic offered to replace the engine with a used one for $2,200. He would put a new intake manifold gasket on the replacement engine, so I would be less likely to run into the same problem again. I learned of gm technical service bulletin #03-06-01-010, with subsequent revisions appended a and b, which describes a repair procedure for coolant leaks on 3.1l and 3.4l engines. The repair procedure is install a new design intake manifold gasket. The material used in the gasket has been changed in order to improve the sealing qualities of the gasket. When replacing the gasket, the intake manifold bolts must also be replaced and torqued to a revised specification. The new bolts will come with a pre-applied threadlocker on them. my son called chevrolet customer assistance and spoke with john brooks, who told him that I would have to have my van evaluated by the service department of a chevrolet dealer before he could offer any assistance. He gave me the following service number with which I could reference the call: 1-201938-040. The intake manifold leak was confirmed at the local chevrolet dealer. The service manager estimated that the engine could be repaired for about $1,650, including parts and labor, but that he couldnt confirm the extent of the damage without getting into the engine. getting into the engine would cost $500, after which there would be no going back. he said there would be no assistance from chevrolet, as I hadn't bought or had my vehicle serviced there.

I noticed a smell of hot antifreeze. Also it would make a lot of noise when starting up. The thermostat never showed anything overheating. Oil didn't show anything on the dipstick. We change the oil every 3000 miles. The dealership that tore into it had said we did not change the oil ever by the looks of the internals. We bought this used 1999 chevy venture lt , august 2000 having 34,000 miles on it already. The previous owner bought this van in october 1998 brand new. How could a vehicle have to have a motor dropped in with only 57,000 on it and have had done everything possible to keep everything in working order. This is not our first chevy, our whole family buys chevys. Just to brag we have 13, and all of them maintained well. One even having over 200,000 miles on it,1995 chevy astro. Anyway, I watch the gauges very closely and never did I see anything wrong.
