What is the Radiator Hose?
Radiator/cooling system hoses are an essential part of your car’s cooling system, which is planned to keep the engine from overheating. When your car’s engine is running it generates heat. The radiator/cooling system hoses carry coolant through the radiator and back through the engine to keep it operating at an optimal temperature. There are multiple hoses in a given system. An upper hose joins the top of the radiator to the top of the engine. A lower hose joins the bottom of the radiator to the water pump of the engine, which keeps coolant flowing through the system.
Facts to Note:
If a radiator/cooling system hose bursts or leaks, the engine will not get the proper amount of coolant and will overheat, possibly triggering severe damage. The hoses are made of rubber, so it is common for them to crack and weaken over time and because of the high temperature in the engine compartment.
How to Fix:
Pressure check cooling system for leaks.
Remove and change the hose that is leaking or blown.
Fill radiator with the proper mixture of 50/50 coolant.
Bleed the cooling system.
Re-check for any leaks.
It is a good idea to change the hoses every 5 years or 40,000 miles. If you see coolant (red, yellow or green fluid) on your driveway get the car checked for leaks. If you suspect a leak, do not delay repair. Driving with leaking hoses can cause severe damage to the engine.
Common signs indicating you may need to change the Radiator Hose:
AC or heater is not working well.
Coolant is leaking.
Steam coming out of the engine compartment.
Bulges or cracks in radiator hose(s)
Importance of this service:
It is essential to change worn or leaking hoses as preventative upkeep to prevent a future failure of these hoses where they may burst, causing engine overheating.
