I have a '91 Maxima. The temperature gauge indicates a normal operating temperature while the car is running.
The car was idling for 3-5 minutes after being driven 15-20 miles. When I shut off the engine, the coolant overflow tank filled up completely, and coolant began gurgling and bubbling, coming out of the pressure valve on the side of the overflow tank.
Another time, the coolant began gurgling and bubbling, but the overflow tank did not fill up, and did not overflow.
Has anyone experienced this situation? Can you offer advice as to what is causing this, and what needs to be repaired? Any links on the Internet that you can point me to, so I can better understand the problem?
Thanks in advance for your help.
