If the question is: why does your top radiator hose get soft while the engine is running? If that's what u want to know, it's because the thermostat in the engine opens to flow the coolant thru the motor to keep the operating temperature from getting to hot. It's stores water in the radiator which cools the water and the thermostat blocks it until a predetermined temp.
A faulty thermostat. leaking head gasket lower radiator hose soft collapses when motor is reved up
Brake system has air in it.
check that the radiator hoses are not soft with engine hot , squeeze hose with your hand you should have strong resistance in hose if they are good other thing is to not fill radiator thru radiator, but to fill thru overflow bottle
Inspect it carefully while the engine is running, look for any leaks at all. If no leaks, it's fine. It's not necessary to replace hoses at set intervals. When cool, the hose should feel firm not hard or soft. It should not have any bulges or cracks or rub through areas.
You've lost a soft-plug (freeze plug). A very inexpensive part, but on many vehicles replacing it requires removing the engine from the frame or separating the engine from the transmission.
The frog is the soft part of a horse's hoof that cushions the weight while running or being ridden. DO NOT PICK OUT WITH HOOF PICK!!!!
running on grass affects a mans movement compared to running on a smooth surface because when he is running on grass, the grass and soil underneath the grass is soft and causes him to not run as fast as he could while on a flat, hard surface.
All the hoses go soft and explode.
Soft engine software works by allowing engineers to test the soft parts of a car body so they can figure out how much force will deform the object which is also known as soft body dynamics.
There are many soft running shoes that would be comfortable running long distances. Nike is a good brand to look into. They have good styles and colors and good performance details.
Coz they do!!
Probably a freeze plug aka soft plug
