1996 Dodge Caravan 3.0 top radiator hose hot and hard bottom hose cold and soft. Did not lose coolant. Temp gauge pegged hot.

  • Your thermostat could be stuck closed (or nearly so), or radiator is (at least partially) clogged - something preventing flow.

This is the classic signs of a stuck thermostat.

It is stuck in the closed position and causing the engine to overheat.

Replace it ASAP before you blow the head gasket.


The same symptoms would also appear if the car's water pump has failed, or is no longer being driven by its v-belt or serpentine belt.
