What does it mean when your coolant reservoir is bubbling?
rising air pressure
Bubbling indicates rising air pressure in the cooling system, which is a sign that the flow of liquid is blocked by a pocket of air. This escaped air causes bubbling in the coolant/antifreeze reservoir, which can often be mistaken for boiling.
Why are there bubbles in the overflow tank?
Problem Bubbles. Though it is completely normal to find bubbles in the overflow tank while the engine is not overheating, bubbles in the coolant could be the sign of a leak at the head gasket. To test for a head gasket problem, check each cylinder of the vehicle with a cylinder leakage tester while the engine is off.
Why is there air in my coolant overflow tank?
Your coolant overflow tank bubbles when the radiator is discharging air which has exceeded the pressure the cap is designed to hold. So why is there air in the radiator? Three reasons in order of likelihood. The overflow tank always needs to have an inch or so of coolant in the bottom when the system is cold.
Why are there bubbles in the coolant tank?
Though it is completely normal to find bubbles in the overflow tank while the engine is not overheating, bubbles in the coolant could be the sign of a leak at the head gasket.
Why does my water pump bubble when I Turn on the water?
A failed water pump seal will allow air to enter the intake or suction side of the pump. This produces bubbling when the trapped air reaches the radiator inlet neck or the expansion valve. Blown or deteriorated head gaskets account for one of the most common and obvious causes of coolant bubbling.

How to tell if your coolant reservoir is overflowing?
How to tell if your over heating problem is caused by the water pump. Faulty water pumps slow or stop the flow of fluid through the cooling system. The result is overheating of the engine. You will see coolant fluid on the ground and around the water pump when the water pump has gone bad. Water pumps either work properly or go bad in a hurry.
Why does my water pump keep overflowing?
Water pumps either work properly or go bad in a hurry. There is no “keeping an eye on it” for validation. If the cap, thermostat and water pump are all fine, the reservoir is overflowing most likely because of a radiator problem. In older automobiles, the radiator was made of copper and aluminum.
