How to Add Car Coolant? Where to Add It?
2 Answers
Car coolant is added to the radiator in the engine compartment. The coolant should be filled between the MAX and MIN level marks. There are two main reasons for coolant alarms: 1. Coolant loss: For example, if the vehicle is parked overnight and a coolant alarm appears when starting the next morning, check for any traces of antifreeze under the vehicle chassis. If present, it indicates a leak in the cooling system that requires repair. If there is no leak, simply replenishing the antifreeze will resolve the issue. 2. Water temperature alarm: If a coolant alarm suddenly appears during high-speed driving, accompanied by a water temperature alarm, it suggests a problem with the engine cooling system. Issues such as damaged water pump impellers preventing proper coolant circulation, malfunctioning cooling fans, or clogged radiator/condenser surfaces impairing heat dissipation can all trigger the coolant warning light.
Last week I just learned how to add coolant because my old car always had high water temperature. Remember to let the engine cool completely before adding—touching it when hot can cause burns, wait at least half an hour. Open the hood and locate the coolant reservoir, a semi-transparent white plastic tank with MAX and MIN lines marked beside it, ensure the fluid level is between them. If it's below MIN, slowly pour in coolant using a funnel; note most types need to be mixed 50/50 with distilled water, or you can buy pre-mixed coolant directly. Don't fill above the MAX line, otherwise when the temperature rises the expanding fluid may overflow and corrode other parts. It's usually located on the right side of the engine near the fan—don't confuse it with the windshield washer fluid tank. Finally, tighten the cap and start the car to check for leaks, and inspect monthly to prevent overheating issues.
