Why is my car intermittently overheating?
A common cause of car overheating is a low-cost thermostat stuck closed, restricting coolant flow. Low engine coolant level. An engine coolant leak internally or externally reduces the level in the system, preventing proper cooling. Blown head gasket.
How do you know if your Headgasket is blown?
Bad head gasket symptoms
- White smoke coming from the tailpipe.
- BUBBLING IN THE RADIATOR AND COOLANT RESERVOIR.
- unexplained coolant loss with no leaks.
- Milky white coloration in the oil.
- Engine overheating.
What causes too much pressure in radiator?
The most common cause of radiator leaks is leaky hoses, but you can have leaks in the radiator itself, too, which can be a bigger problem. The coolant continually running from your radiator to your hot, running engine and back again creates a lot of pressure.
Why is my coolant low but no leaks?

Why is my coolant not circulating?
The coolant level could be extremely low because of long-term neglect, or because a coolant leak has developed in the radiator or radiator hoses. The thermostat that allows coolant to circulate may be stuck in the closed position or a clog may have developed, perhaps from debris in the cooling system.
What happens when a thermostat goes bad?
Because your thermostat controls temperature of fluids from the radiator hose, a bad thermostat will cause your car to overheat. When the engine temperature has reached the operating level, it should allow coolant to flow to the engine and regulate the heat.

Where do you drain coolant from a radiator?
Look for the drain plug (the white or black plastic wingnut) near the bottom corner or side of the radiator tank. Place a bucket underneath the drain plug so the coolant doesn’t spill when you drain the radiator. Unscrew the drain plug and let the coolant flow into the bucket until your radiator is empty.
