Keep your clients on the road with expert radiator hose repairs
Radiator hose leaks are one of the most common automotive problems. If not controlled, they can lead to overheating, engine damage, and more expensive repair bills. But rushing to fix it can backfire. Let’s learn how to solve this problem effectively and safely.
To fix a radiator hose leak, first inspect the hose for cracks or bulges. Drain the coolant, then loosen the clamp to remove the faulty hose. Clean the joint, replace the new radiator hose, and secure it with a new clamp. Refill the coolant and check for leaks. Finally, test it.
Can You Fix a Radiator Hose Without Replacing It?
In most cases, no, although some car owners try to fix it with tape or sealants, these are only short-term solutions. Auto repair shops should avoid doing this on their customers’ vehicles.
If the hose is degraded, cracked, or bulging, just replace it with a new one.
