The problem with my Venture turned out to be a leaking water pump based on the mechanic's diagnosis. So far, so good. Although, replacing a $300 water pump at 82,000 is somewhat ridiculous! the mechanic says it was due to the fact that the extended life coolant (dex-cool) doesn't perform like Chevrolet says it should, and it is the cause of many water cooling system problems. He recommends changing the ext. Life coolant every other year just like regular coolant, and judging from the look of the old coolant, I believe him! August update: I am now facing a transmission rebuild that the transmission man says is "typical" of these Venture due to a mfg. Defect causing the transmission oil pressure to drop and kick the oil pump into high pressure mode forcing fluid through the system at such high pressure that every time it shifts, it feels like the transmission will jerk itself loose from the vehicle.

Has 3.4 L engine with lower intake gasket leaks. I purchased an extended warranty when new and it covered the $700+ repair cost. Will this happen again in another 48K when out of my extended warranty?

1 inch of sludge in engine, lost of coolant, the engine pinging and knocking, steering and brakes locked up which caused the accident while driving. We changed the oil pump, oil connecting rod, spark plugs, spark plug wires, coils and still engine is broken. Started with coolant in the oil. Unsure symtoms leading up to the accident.

Early failure of the lower intake manifold gasket, which caused lost of coolant. 40,000 miles on 1999 Chevy Venture. Believe a poor design of gasket and that the radiator level is below that of the manifold. An air pocket can be trapped in the manifold and when the engine is off the residual heat of the engine cooks the gasket. Believe this theory is supported by the coolant sensor is on even though the level in the radiator is full and the reservoir is full.

1999 Chevy Venture passenger van with less than 58,000 miles experienced an intake manifold gasket failure. Chevrolet customer support representative indicated an "advisory" has been issued for the 3.8 litre V6 engine but that she has also received "several" calls on the 3.4 litre V6 engine. Given vehicle age, number of miles, and driving patterns, a failure of this magnitude and cost should not occur.

I have a 1999 Chevy Venture. I have had nothing but problems with the injectors causing the check engine light to come on. This happens every couple of months. I also have a problem with the intake on the same vehicle. It is the 3.4 engine and there are a lot of people with the same problem. I feel that a recall needs to be required to fix this. After spending thousands of dollars on a vehicle is should be right or at least fixed on good faith.
