What to Do When the Motorcycle Radiator Overheats?
2 Answers
Do not attempt to continue riding to avoid major engine damage. After some time, check if there is any water leakage under the motorcycle. Wait until the temperature gauge needle drops to a suitable position, then turn off the engine. Use a wet towel to cover the radiator cap. After the steam pressure is completely released, open the radiator cap to check the water level and quality in the radiator, and whether the fan belt is abnormal.
I've been around the motorcycle scene for quite a while, and encountering high radiator temperatures isn't uncommon for me. When the temperature gauge spikes, I immediately pull over to let the engine cool down because continuing to ride could burn out the engine or, in severe cases, even cause an explosion and injuries. After stopping, don't rush to touch the radiator cap—it's too hot and can release scalding steam. Wait about ten minutes. Then check if the coolant reservoir level is low; if it is, top it up with distilled water or specialized coolant. Next, see if the fan is working—if it's not spinning, it might be a relay issue or a short circuit in the wiring. If the radiator is clogged, you can gently brush off dust from the fins. A faulty water pump usually makes a humming noise or shows signs of leakage. These minor checks can be done yourself, but if the problem persists, it's best to call a tow truck and take it to a professional shop. Develop a habit of regular maintenance, like changing the coolant and cleaning the radiator every quarter, to reduce such issues. In short, safety always comes first—don't risk riding just to save time.
