Can a clogged radiator cause bubbling in overflow?
a clogged radiator can cause this to happen too, the coolant doesn’t circulate fast enough and cause’s localized boiling. a bad radiator cap can do this also, the system needs to be under pressure to raise the boiling point of the coolant, if it’s not, it won’t and it will boil at a relatively low temp.
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.
Can a thermostat cause bubbling in overflow?
a thermostat that’s sticking shut intermittently can stop coolant flow and cause the car to get hot and boil the coolant, that will cause bubbles and spurting in to the overflow. ONLY USE OEM T-STATS in these cars [not yelling, that just means it’s important;]
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.

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.
