Tips for Repairing a Leaking Radiator Hose Tips for Repairing a Leaking Radiator Hose

One of the most common reasons an automobile stalls is a leaky radiator hose. Overheating can cause excessive damage to a vehicle. The best way to prevent such hazards is to inspect the radiator hose regularly. When you find cracks or bulges, the time has come for a change.

Step 1: Drain the Radiator

The first indication that a radiator hose may be leaking is a slow rise in the engine’s temperature. Keep watch on the gauge and make a note of the normal temperature. If you see the needle above its normal position between Low and Hot, check the engine: The radiator may be low in antifreeze. If that is the case, inspect the radiator hose. It likely has a leak. Let the engine cool and then drain the antifreeze through a valve on the bottom of the radiator.

Step 2: Locate the Leak

The radiator hose circulates antifreeze from the radiator through the engine. Most cars have one at the top of the radiator and another at the bottom. Decide which of these hoses is leaking. A hose clamp will hold the hose on each end. Remove the clamps, twist free the hose and take it to an auto parts store or dealership for a replacement.

Step 3: Replace the Hose

Install the new hose fastening it again with hose clamps. Refill the system with fresh antifreeze. Start the engine and inspect it again to ensure the radiator hose now shows no leaks.
