Oldsmobile Aurora Radiator Hose

Radiator 1995 Oldsmobile Aurora 4.0L V8. Has new water pump, thermostat, belt, upper lower hoses,radiator. Upper driver side of radiator inside near air cleaner there is a hose coming off it! Where dose it go and what does it supply??? Driver side vent always blows cold air.

Mine is capped off with a bolt and a hose clamp. In the winter the driver side would blow just cold air and still dose! So i guess my question is why doesn't the driver side vent have no heat or defrost just cold air but the passenger side has good hot air upper and lower heat.

ANSWER:

By what you are describing, this sounds as if the radiator has been replaced. Replacement radiators come with all possible fitting, depending on application. If a port / fitting is not needed for the cars original setup, then it just gets plugged off. Nothing to worry about. May be for a different transmission cooler setup.

The above would have nothing to do with the heater, A/C problems you are having with your Aurora. Most likely you have a faulty temperature door actuator motor under the dash for the malfunctioning side. Each side of the dash has a motor that controls a door to give the proper air temp you set for either side. When they fail this would cause your difference in temperature from the passenger side to the drivers side.
