1997 Plymouth Voyager 4 cyl Front Wheel Drive Automatic

I replaced the radiator with a new one today. I bleed the system for air pockets. I checked upper and lower hoses the temperature ran hot and there were no leaks. In addition, I checked the heater core hoses one was hot and one was semi hot. I checked the temp. Gage and it stayed at 200. I also ran the heater but it never got hot. Fans did turn on. I ran this test for 15 min. Customer implied that the heater didn't blow hot during the winter but it did turn hot when it over heated. I also took it on a test drive around the block and everything checked out. Customer drove across town and it started bubbling through the reservoir although customer stated that the temp. Gage was still at 200. It was only bubbling through the reservoir. Prior to replacing the radiator I had replaced the thermostat and the water pump. Did I miss anything that would have caused the bubbling in the reservoir? Why did it bubble?

Hi, First Is The Temp Gauge accurate? To Confirm This, Hook Up The car to the Scanner Look At data For Cooling Temp Sensor. Also Check Temp When Cooling Fans Come on and off. These 4 Cylinder Vans Had problems, With The Heater cores Getting Air bound. We Use to Take One hose Off The heater And Fill It with anti Freeze, And Put back on. Recheck the cooling level. With The heater And Ac off. Also Check That You have the right Pressure Radiator cap, and that it holds Pressure. If all Of this above Is correct, Then the only Thing left Is the head gasket.

Hope This Helps You,
Good Luck
