Upper Radiator Hose

The upper hose carries hot coolant from the engine to the radiator. However, it can dry out, crack, collapse, or break, leading to coolant leaks or insufficient coolant flow over time. If left unchecked, this may result in overheating and even engine failure. So it's vital to inspect your radiator hose regularly. Whenever you notice leaks, hardened or brittle hoses, spongy or soft spots, or visible cracks and bulges, it’s time for a replacement to avoid more costly damage.

Installation Tips and Related Parts

Replacing the upper radiator hose is a good time to take care of a few other maintenance tasks as well:

• Safety first: Always let the engine cool completely before removing the upper radiator hose. This prevents burns from hot coolant or steam.
• Check the clamps: Don’t reuse old, rusted, or stretched clamps. Install new hose clamps to ensure a secure, leak‑free connection.
• Inspect the thermostat: The upper hose is often connected to the thermostat housing, so it’s smart to check or replace the thermostat while the cooling system is drained. This helps improve long‑term reliability.

Differences between the Upper and Lower Radiator Hoses

Don't accidentally buy the wrong device! You need to pay attention to the difference between the upper and lower radiator hose because they have different roles within the cooling system.

• The Upper: This is a pressure hose that carries hot coolant from the engine to the radiator, where it gets cooled.
• The Lower: This is a suction hose with a spring inside to stop it from collapsing under pressure. It connects the radiator to the water pump, which sends the cooled coolant back into the engine.
