Why is my coolant bubbling hot?
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. One of the most common causes is a blown head gasket, in which the air pressure inside the cylinder heads is transferred to the cooling system.

What causes coolant reservoir to overflow in Toyota Camry?
This would force out the fluid that was already in the reservoir. Then when the car gets turned off and cools down, the pressure drops and eventually sucks the fluid back in, only now the reservoir will be nearly empty. I had the same problem with my Camry.
Why does my car’s coolant bubble when I turn it on?
A thermostat opens and closes to regulate the coolant flow for engine warm-up and circulation. Air bubbles in the coolant, at the radiator or expansion reservoir, means air has entered the system at some point. This can lead to overheating. A radiator cap functions as a pressure seal, and keeps the cooling system pressure raised.
Is the coolant reservoir on my Toyota XLE nearly empty?
Hi all, I recently bought a 95 camry XLE. It runs great, but I noticed the engine coolant reservoir was nearly empty. I added fluid to both the reservoir and where the radiator cap is and then checked it several days later.
Where is the coolant cap on a Toyota?
I added fluid to both the reservoir and where the radiator cap is and then checked it several days later. The engine was cool and the reservoir was nearly empty. I noticed today after my commute that when the engine was still hot, the reservoir was filled to the brim/boiling over. I never added more fluid.
