2004 Nissan Maxima 6 cyl Front Wheel Drive Automatic 112000 miles
The heater blows hot air as long as the RPM's are above 1500. Once below at a stoplight or in traffic the heater only blws cold air. The temperature gauge is normal doesn't go up or down. Once I begin to increase RPM's the heater will begin to blow hot air again. At the same time there is a gurgling sound when I start to accelerate and the hot air will then start. I went to a dealer and they said it is a head gasket due to exhaust gases backing into the coolant. I wasn't convinced and I didn't want to spend the money on a head gasket repair if it was something else easier to repair. Any ideas?
