Coolant Hose (Radiator Hose)
Coolant hoses carry coolant between engine, radiator, heater core and expansion tank.
What is Coolant Hose (Radiator Hose)?
They are made of reinforced rubber or plastic. Hoses age with heat and pressure. Clamps hold them on their connections. Squeezing a cold hose shows whether it has become hard or spongy. Oil contamination softens rubber hoses. Constant-tension clamps are used on many cars because they keep the grip as hoses expand and contract.
How it works
Hoses form the flexible links in the cooling circuit.
Why it matters for your car
Swollen, cracked or soft hoses should be replaced. A burst hose can quickly cause overheating.
