Tl* - the contact called to file a complaint about the service bulletin she found on our website, #030601010 dated 03/01/03. The contact states that her 2000 chevrolet venture has had the same repair that the service bulletin refers to. The repair was done on 12/21/06 for the lower intake manifold, and the repair cost the contact $696.07. The contact does have her repair order.
Intake manifold gasket failed causing coolant to mix with engine oil.
We have spent 3 years flushing radiator with dexcool--still having overheating which causes problems with our transmission--every time seeing sludge in overflow tank within a month after fresh flush--this month we have replaced water pump, and replacing radiator, oil cooler, and going back to regular green antifreeze after hearing of similar problems and worse in chevrolet models using dexcool!! Unknown if damage has been caused to transmission for 3 summers of overheating...can't drive in stop/go traffic safely in warm weather knowing that cooling system/transmission will fail in those conditions. We've spent several hours stopped under shade trees to let engine cool down enough to get to destination.
Noticed coolant leaking brought into my mechanic he diagnosed " replace intake manifold gaskets", brought van to chevy to see if perhaps a recall because I was told by mechanic that this problem is common with this engine, but I was told no recall and they are unaware of a problem with this engine. So I paid $1,265 to chevy to repair their defect on a 2000 chevy venture with just under 25k miles. And they wonder why people are buying foreign made cars!!!!!
I noticed red fluid on one of the lines below in the area of the coolant reservoir. I do have dexcool in the system. I have not diagnosed the problem as to where the coolant is leaking from but I notice the reservoir gets low periodically. I fear it is leaking from the gasket but not sure yet. I have nothing but problems with this vehicle. I have had to spend $600-$1000 every year which a couple of the repairs gm took care of after reaming them out. Their product is terrible and I will never buy another gm again.
Vehicle failed to start. Change fuel filter. Didn't fix the problem. Now my dex-cool is leaking, shorted out cam position sensor. Has had low coolant for at least a year. Can't understand how a vehicle can use so much coolant. Vehicle is still parked, not running, had mechanic check vehicle with a scan tool, says the cam sensor is bad.
We have a 2000 chevy venture wb edition and have had problems with the intake manifold. It appears to be leaking and we are in fear that it will do harm to the engine. I have talked with the mechanic and he says that this is a common problem with this vehicle but gm has never issued a recall. Whay is that? If this is so common why not fix it!
Dt: the consumer starting experiencing problems with the vehicle on mar 18th, 2005. The consumer felt a skip or sputter while driving or at a stop sign. The dealer told the consumer to put dry gas in the vehicle which solve the problem. The check engine light illuminated, so the dealer tightened the gas cap. The ABS light illuminated.
I have a chevy venture 2000. For the last 6 months I have had oil spots on the ground in the garage, and have had to keep filling up the coolant resevoir tank for a few weeks now. I had the car checked at the dealer for the oil spots after having them do an oil change months ago. They told me not to worry about that small amount of oil. However when I took it in to get checked why I was having to add coolant they found that the intake manifold gasket was leaking. It cost me $600.00 to have this repaired. My van has 86k miles on it. It has had the gasket replaced twice now. I have researched info for this problem and have found many other vehicle owners of the 3.1l and 3.4l motors in gm's having the same problem. Why does this continue to be a problem? This has to be damaging the engine having coolant being able to leak into it. The service station I went to does several of these a month on 1998 to 2001 models with these engines. They told me that there is a flaw with either the gasket or the dex cool that corrodes the gasket.
Dt: fuel system is not connected correctly which causes the fuel to mix and to drain. The head gasket blew off because of this.
Losing oil on 2000 chevrolet venture minivan and went for service. They found that the intake manifold gaskets leaking coolant and oil. They explained this would have caused critical engine issue if left. Have read many other complaints with this exact problem and also service notes from gm on this topic. The van has only 49000 miles. I paid over $950 to fix a gm defect.
The air bag light remained illuminated while driving. The vehicle is at the dealer. *ak the passenger seat belt pretensioner was installed with an activation cable under the seat track. Over time, the wiring in the cable shorted internally requiring replacement. Without replacement the airbag system was inoperative. There was also a coolant leak which was found in the lower intake manifold gasket. *sc
Labor day 2004 traveling through rocky mountain national park, engine coolant overheated. Had replaced coolant 2 months previous. Temperature gauge now always shows cool. Today had routine oil change and shop advised intake manifold gasket leaking and needing replaced. Upon researching the problem, discovered it is extremely common on chevrolet 3.4l engine and often leads to cam shaft and even total engine failure and replacement. Gm currently ignoring condition.
At approximately 47,000 miles there was determined to be a consumption of coolant, with no leaks outside of the engine. There was then a leak that started outside of the engine a few hundred miles later. Vehicle was taken to dealer for repair ($800) of the intake manifold gasket. Upon research on the internet it was determined that this failure is very common to the gm v6 engines (which the service manager confirmed). This needs to be a recall!! Gm is aware of this with technical service bulletin 03-06-01-010.
The vehicle developed a smell that was foul, with a slight odor of antifreeze. Dealer replaced the filters. However, the smell was still there. Currently, a coolant light came on and the antifreeze was leaking into the oil.
I'm writing you this letter since gm has refused to acknowledge they have a factory defect in the intake manifold gasket and bolts of may of their gm vehicles.: to include my 2000 chev venture. Recently while on a long trip over the holidays I noticed the low coolant light had illuminated and discovered our coolant was leaking. I took it to the shop today and it cost me $895 for the repair...not bad compared to some but still a cost one wouldn't expect to pay on a car only 3.5 years old and 70k miles. My wife and I have done some extensive research and found this seems to be a significant problem with gm cars but yet there is no recall for the problem. The result of these gasket failures is clearly a design flaw and we've n documentation where your company is paying for other models manifold repair cost. Looking over this site and others dedicated to this problem I've found numerous other stories similar and many even worse. I find it hard to believe gm is not stepping up to fix the cost of these repairs....they will lose my business.
Premature failure of intake manifold gasket//g.m. Has new revised one ??? Car has 40,000 mi 2000 chev. Venture 3.4 motor it is a known fact that g.m. Has a big problem out there. Poss. Damage to internal motor if coolant leaks inside!!!! Very costly too consumer./// the dexcool coolant seems to be the problem also// very corrosive to gaskets. Looked at mitchell. Tech. Bulletin found out about early intake gasket failure.with note on revised gasket. I seem to feel g.m. Should take care of this even if a deductible applies .thank you for your time. If you can lead me in a direction to take I would appr. It. S.t.
I own a 2000 chevy venture with 52000 miles. I recently noticed small puddles of anti-freeze on my garage floor. I immediately took my van to my mechanic and he states that a leak is coming from the manifold intake gasket. I discovered this is an ongoing problem with gm vehicles with this type of engine and numerous complaints have been filed. Gm knows of this manfacturer defect but fails to act in repairing this problem. This is a serious safety issue and can cause major engine problems if not repaired if other damage has not already occured due this manufacturer defect. The out of pocket cost to the consumer is seven hundred dollars on up.
2000 chevrolet venture van required replacement of intake manifold gaskets at aproximatley 60,000 miles fortunatiely no engine damage and cost was only around $600.00.
61,000 losing collant due to intake gasket leaking. I have read several complaints of this problem and nothing is being done. Why not?
Had to replace the lower intake manifold on the coolent system
I took our 2000 chevrolet venture minivan in for service and they found that the intake manifold gasket was failing. This was causing anti freeze to leak into the engine which eventually would have caused the engine to need to be rebuilt. Come to find out the next day there is a gm tsb 03-06-01-010 on this exact problem. Our van has only 45,000 miles on it and I do not believe this should fail especially with so few miles on it.
1) vehicle consistently low on oil. 2) determined that oil was linking into the cooling system due to failed intake manifold gasket. 3) gasket (part# 89017279) was replaced.
Just another venture with faulty intake manifold gasket. Also had short in fuse terminal block. Last chevy I will own.
Purchased a new chevy venture van in may of 2000, at 19,000 miles it the intake manifold gasket needed to replaced. Work was performed under warranty at the same dealership. Now at 42,800 miles, the same gasket is leaking again. Although, I purchased the extended warranty in may 2000, they say someone called & cancelled the warranty a year ago. How can they avoid the huge number of complaints concerning this problem with no recalls?
The coolant light keeps coming on and off. We have added coolant throughout the winter and then again a couple of weeks ago (june 2004). We believe there is a defect or a leak.
Since purchasing my 2000 chevrolet venture minivan in october, 2000, I have been experiencing loss of coolant since december, 2003. At this time the car had just over 75,000 miles on it. None the less I had kept scheduled maintenance on the van. On every scheduled maintenance chevrolet prescribes ( from 7,500 miles to 90,000+) "check for oil and coolant leaks" is listed. I find it difficult to believe that at no time during any of these check up the mechanic at the dealer did not notice a coolant leak until 80,000+ miles later and after my warranty has expired. Now, I have been advised that the intake manifold is leaking and the repairs are going to cost ~$900.00. I contacted gm customer service, and was given several excuses to justify chevrolet's action, (or lack therof), from "that's a lot of miles. And any part is going to wear out after a while" to "if there needed to be a recall it would have to be demanded by the government". Hogwash!!! Based on the number of complaints I have read this evening, and even the verbal confirmation from my service advisor that "we're seeing a lot of these", chevrolet does not have to wait for the government to say, we have a problem and we need to fix it.
Cooland level light came on next day discovered coolant leak right side
When I bought this 2000 chevrolet venture van I purchased the mfg.extended warranty up to 75,000 miles. Right after the extended warranty ran out, the van developed a serious head gasket leak and the transmission has been going crazy. I checked around and found out that both these problems are very common on the venture van! I call the mfg. And was told they would not help! This is the reason buyers feel that they made a mistake buying american made vehicles. These are problems that have occurred in many instances and the mfg. Knows this and are not willing to do a recall. I should have bought a toyota. General motors knows these problems exist and are due to poor workmanship and do not care about owner loyalty or retaining their customer base for future sales. Both of these problems are more widespread than what is documented due to lack of reporting.. Please help!!!
