What is the tube connected to the radiator?
The radiator hose is an important part of your vehicle’s cooling system. The hose carries the coolant to the radiator, where the fluid is cooled, then back to the engine to keep the vehicle from overheating.
Why is the top radiator hose hot and the bottom one 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.
How is the coolant returned to the radiator?
The smaller spring that can’t be seen is how coolant is returned – through the center of the cap. The process of returning coolant back to the radiator is possible because the combination of the reduced steam pressure allows the atmospheric pressure to push coolant from the tank back into the radiator through the vented radiator cap.
Why does a radiator have a non vented cap?
As temperatures and pressures increase, the expansion tank allows the cooling system to expand without bleeding any off to the atmosphere. With this type of system, if the radiator has a cap it will be a non-vented cap; the expansion tank will have the vented cap in case the pressure exceeds the expansion tank’s capacity.
What causes coolant to leak from lower radiator?
Coolant level does go down which confirms a leak and jives with the hot coolant smell. Noticed the metal pipe connected to the lower radiator hose is very rusted and corroded. Will look more into this area for the leak.
