How to Deal with Low Coolant Level in the Vehicle Radiator?
2 Answers
Solutions for low coolant level in the vehicle radiator are as follows: 1. If it's a pipe leak, go to a repair shop to patch it up or replace the pipe. 2. If the oil cooler sealing ring is damaged or has pinholes, the sealing ring needs to be replaced. 3. If the radiator cap is not sealing tightly, try resealing it. If it still doesn't seal properly, go to a repair shop to replace it. The reasons for low coolant level in the vehicle radiator are as follows: 1. Leakage from pipe joints or the pipe itself—replace the pipe or reinforce the seal. 2. Cracks in the cylinder block, or a loose or damaged cylinder head gasket, causing coolant leakage. 3. Damaged or pinhole-prone oil cooler sealing ring, leading to coolant leakage. 4. The radiator cap is not sealing tightly. 5. Leakage from the heater radiator. 6. Leakage from the three-way connector.
That day while driving on the highway, the engine temperature warning light suddenly came on, so I quickly pulled over to a safe spot. After waiting half an hour for it to cool down, I carefully unscrewed the radiator cap to check and sure enough, it was empty. Remember to pour cool water over the cap first to prevent burns! As an emergency measure, I added two bottles of mineral water temporarily, but only filled it up to two-thirds to prevent thermal expansion from damaging the pipes. I drove to the nearest auto repair shop to check for leaks, and the mechanic said it was caused by a loose hose clamp leading to a slow leak. They tightened the clamp and reminded me that the radiator should be filled with antifreeze instead of water, otherwise it could freeze and crack the radiator in winter. Now I’ve developed the habit of checking the coolant every week, and I always keep a bottle of distilled water in the trunk for emergencies.
