What causes the coolant in an engine to boil?
Whether it’s a faulty pressure cap or crack in the engine block, if the pressure at which the coolant/antifreeze flows through the engine is affected by a leak, the fluid will reach boiling point causing the engine to overheat. What is the boiling point of coolant/antifreeze?
What to do about Bubbling coolant in expansion tank?
Drop the old coolant and replace with new and bleed the system from one point on the coolant pipe above the radiator, and an 8mm bolt next to the thermostat housing. The tank now doesn’t over heated and the fan kicks in when it should keeping the system cool. Hope this helps.
What should I do if my car coolant is bubbling?
Potential radiator damage. The fix: When flushing the radiator and cooling system, make sure you run the engine with the pressure cap off for 15 minutes after refilling the system. This will bleed any air from the radiator and cooling system before you replace the pressure cap. Read our comprehensive guide on how to do a coolant flush.
Why does coolant bubble when the fan is turned on?
One reason I consider air v. exhaust in they system is that the steam/smoke occurs as the temp gauge raises and not from the get go. I wish I had seen if the coolant itself was hot to the touch. The bubbling starts when the thermostat opens and the fan turn on. But while I did not touch it I could feel heat emanating from the reservoir tank.

What causes car radiator to overheat and boiling?
What Causes Car Radiator Overheating and Boiling. Coolants pass through the engine block, flowing into the radiator to draw out excessive heat. The coolant then recycles through the engine. When the radiator fails to function correctly the coolant returning to the engine block is too hot, and as a result it boils over.
How does the cooling system in a car work?
The cooling system in your vehicle is comprised of passageways throughout the engine block and heads, a water pump that circulates coolant, a thermostat that controls coolant temperature, a radiator to keep the coolant cool and a radiator cap to control the pressure of the coolant.
