Your car does not run hot but it bubbles when you turn it off?

It is normal to boil when you turn the car off. When the coolant stops flowing, the coolant in the hot engine boils and pushes steam out of the engine. The recovery tank collects the excess and allows it to go back in when the engine cools.

Why is there coolant coming from the reservoir and spraying on the motor in a northstar 4.0 engine 1996 Oldsmobile aurora?

There is air in the system or there is an overheat problem. The main reasons for this type of coolant loss are: An air lock. The pressure cap has failed. The head gasket is blown. The thermostat has failed in the closed position. Inspect the rubber seals in the cap and discard and replace the cap as necessary. Turn on the ignition and put the heater controls to HOT. Refill the system. Run the engine, check for loss. If not OK, switch off and let the engine cool. With a cool engine fill the reservoir right up and leave the cap off. Switch on engine and look for bubbles in reservoir. Bubbles should clear in a few seconds. If revving the engine produces more bubbles, headgasket has failed. Do not leave the engine running longer than necessary. Beware, the water will get hot, expand and spill out. If previous tests fail to show the fault, remove the thermostat and place in pan of water. Heat the water, the thermostat should open wide before the water boils.
