Steam coming out of the hose where upper radiator hose connects to the radiator. Hose itself has no damage just seems to steam from where it connects to the radiator. Car overheating
Three possibilities come to my mind:
- As noted in the first comment above, your hose clamp is failing or loose. Check it.
- The hose is damaged or leaking. Replace it.
- The radiator fitting is damaged or leaking. This may require replacing the radiator.
Also, I'll add, based on later information that you posted. Perhaps this is not the root problem. If your radiator is clogged or the thermostat is failed and the pressure cap is malfunctioning, then perhaps this is the next weakest link.
