Car coolant boiling is a common problem in vehicles. It is caused when the engine overheats due to being stuck in traffic. What happens is that the coolant boils in an enclosed space with no way of venting out, causing pressure to build up and disrupting the flow of fluid through the engine block.

What does it mean if your coolant is boiling?
When there's a leak in the cooling system, the pressure of the liquid drops and so does the boiling point of the coolant/antifreeze. Cooling systems are pressurised to raise the boiling point of the fluid, with the pressure cap and the overflow helping to raise the temperature at which the coolant/antifreeze boils.
How do you clear a clogged radiator?
Drain the coolant from your radiator by opening the drain valve on the bottom of your radiator. Next, drain the coolant from your engine block by opening the block drain also. Add the purchased radiator flush to the radiator and let the car run. Drain like the old coolant, and suddenly your car is clean and fresh.

Is Bubbling in coolant reservoir normal?
Problem Bubbles It's perfectly normal to have bubbles in the expansion tank when the engine is not very hot, but if they appear in the coolant, it could be a sign that the head gasket is leaking. To check for a head gasket problem, test each cylinder in your vehicle with a cylinder leak tester with the engine off.
