Why does the lower radiator hose have a spring in it?
Why does the lower radiator hose have a spring in it?
The purpose of the hose spring was to prevent collapse during the vacuum portion of the fill cycle. It is possible for the lower hose to collapse slightly due to the water pump drawing water out of the lower hose faster than the gravity-fed water from the radiator replaces it.
Does lower radiator hose need a spring?
An example is in the lower radiator hose. We’re going to get arguments on this one, especially from hose manufacturers, but all molded lower radiator hoses should have an anti-collapse spring. The hose collapses causing coolant starvation and overheating on the open road at high rpm.
Is the lower Rad hose hot or cold?
The lower rad hose is hot, the thermostat housing is warm, the rest feels cold. A large percentage of vehicles have the thermostat on the upper hose. On these I can see the heated coolant thermo-circulating through the engine. But on mine…????? Someone please explain.
What causes the lower radiator hose to heat up?
Thus, making the lower radiator hose to heat up. It may happen that your car might get low on coolant and is not able to reach the lower radiator. As a result, the lower hose emits cold air.
Can a cold lower radiator be a problem?
In many cases, when it comes to a cold lower radiator hose, there is actually no problem at all! The engine needs to be really hot and almost overheat before the thermostat lets the coolant pass by.
What should I do if my radiator hose Pops?
Clamps on radiator hoses often get changed. As old as our cars a getting, most have been through at least 2 or 3 previous owners hands. Don’t be surprised to find that your clamps aren’t the stock ones. If you’re going to use metal worm clamps, I’d suggest looking into heavy duty ones.

How does a lower Rad heater work on a 1HD-T?
Anyway, I have a lower rad hose heater on my 1HD-T and it’s installed in the…you guessed it…lower rad hose. But, the thermostat lies between the heater and the engine, effectively blocking the flow of heated coolant into the engine. The area around the heater is relatively wide open, so a considerable amount of heat is lost to the air.
