Why does my radiator reservoir bubble when I cool down?
If the reservoir is presurized, the overheat symptoms can be the same. But also if the bubbles come up during cool down it can just be presure equalization allowing air to enter through the radiator cap and down a passage moulded in the reservoir.
Is the coolant in the reservoir boiling or overheating?
Overheating and boiling coolant in reservoir and more! My 93′ Camry (3vz-fe) just overheated yesterday and the coolant in the reservoir was boiling to the point that it completely evaporated even after i turned the engine off for about half an hour. i have noticed some small leakage before in my garage, but nothing tremendous.
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 is coolant Bubbling Under the head gasket?
EDIT: It has been pointed out that the bubbling could be coming from a leaky hose drawing air into the coolant tank. However, a leak that lets air in will also let coolant out; so you would expect to see a puddle of coolant under the car after a while. A leaking head gasket nearly always leads to an overheating problem.

What causes coolant to overflow from the radiator?
Your problem may simply be a loose or damaged cap not keeping coolant where it needs to be. The radiator cap is designed to allow access to fluids in a ‘closed’ system. The coolant used to cool the engine does so at maximum efficiency when kept at specific pressure. Check your owner’s manual for proper cap replacement.
What happens if there is a bubble in the radiator?
If bubbles are present during the test, combustion gas is leaking into the cooling system and this will need to be repaired. If left untreated, it could lead to a blown head gasket, which could leave you stranded. Geoff Hineman has been a professional writer since 2001.
What causes a radiator to have over boiling point?
What you are describing is usually caused by a weak radiator cap. Weak meaning it is no longer holding the pressure which is needed inside the system. Since you said you just replaced the cap, having just water in the system will lower the boiling point and may cause over pressure in the system.
