What Is a Radiator Hose?

Radiator hose

Engine coolant is the fluid used to prevent your engine from overheating. In its simplest explanation, the cooling system consists of the radiator and water pump, which takes hot coolant from the engine, cools it down, and then returns it to the engine. Rubber hoses connect the engine and radiator, transferring coolant between them.

What Does a Radiator Hose Replacement Include?

Your engine coolant must also be drained to enable the replacement of the bad hose. Now is a good time to replace it with new coolant, but if the coolant you drain is new or in good condition, you can put it back into the engine after replacing the hose.

What Happens If You Don’t Replace a Bad Radiator Hose?

When a hose springs a leak, coolant will escape, causing a thick cloud of white steam. If you continue to run the engine it will overheat, as indicated by your temperature gauge or warning light. If you continue to drive when it’s overheating, your engine can suffer serious internal damage. It can even seize and stop running permanently if it overheats too much.

How Often to Replace Radiator Hoses

As a general guideline, you should replace your radiator hoses every four years or 60,000 miles, but be sure to check your owner’s manual or use the free FIXD app for accurate maintenance schedules. Hoses can wear out over time, so it is best to replace them when they begin to show signs of wear, and before they begin to leak. This is either a beginner or intermediate job for the DIYer, depending on the location of the hose and how difficult it is to reach.
