: the contact stated the temperature gauge on the vehicle rose above normal while parked. The contact filled the water tank, which cooled the vehicle for 30 minutes. However, the temperature rose again. The vehicle was taken to a private repair shop, who determined there was a leak in the intake manifold gasket. There were no immediate repairs made.

Also, while doing research she learned that this problem was occurring between 60,000-80,000 miles. She found two websites with complaints from other Aztek owners. In addition, when coming to a stop, the heat stopped coming from the dash vents. Dealership purged an air pocket found in the cooling system. The consumer and manufacturer was able to come to some sort of compromise regarding the cost of replacing the intake manifold gasket.
