Why is my upper radiator hose not hot?
If the upper radiator hose already gets hot before the engine has properly warmed up, it means the thermostat is not closing properly or even is constantly open. If it does not get hot at all, it means the thermostat is blocked. In both cases, the thermostat should be replaced immediately.
Is upper radiator hose supposed to be hot?
The top radiator hose is usually but not always the location of the thermostat. Either-way, the top hose gets hot after the thermostat has opened. The time the thermostat takes to open depends upon factors such as: Coolant temperature.
Why is my upper radiator hose empty?
The most common cause for radiator hose collapse is a vacuum issue caused by a faulty radiator cap. As the engine cools, if fluid cannot return to the tank, this will also cause a vacuum. Additionally, it is possible that your radiator is clogged or dirty, but if that’s the case, you’re likely to have some overheating.
Why is my upper radiator hose hot and lower cold?
Once the thermostat opens, hot coolant will flow to the radiator. The top hose will be hit, and the lower hose will be somewhat less so. If the lower hose remains cold, it means that there is a blockage in the radiator.

What kind of water heater does not store hot water?
Tankless or Demand or “Instant” water heaters may be electric, gas, or possibly even oil-fired devices that do not store any volume of hot water. When you turn on hot water at the tap, water flowing through the system activates a control to turn on the heater that in turn heats water as it passes through the device.
Why are there two hoses in a radiator?
Radiator hoses are a vital part of the cooling system that carry hot coolant from the engine through the radiator and circulate it back — cooler — to the engine again. There are two hoses, the upper and lower, and they’re thick and sturdy enough to handle both high pressures and immense heat.
