What Causes the Coolant to Decrease Too Quickly?
2 Answers
The reasons for the coolant decreasing too quickly are: 1. Unreasonable cooling system design; 2. Poor circulation leading to rapid consumption; 3. Leakage; 4. Coolant entering the cylinder and being burned or entering the oil pan. The full name of coolant is antifreeze coolant, which is a type of cooling liquid containing special additives, mainly used in liquid-cooled engine cooling systems. It contains: calcium chloride, methanol, ethanol, ethylene glycol, glycerin, etc. The method for replacing coolant is: 1. Open the car hood after the engine has cooled down; 2. Open the coolant reservoir cap; 3. Lift the vehicle and open the radiator drain plug, drain the old coolant and reinstall the drain plug; 4. Lower the vehicle and pour new coolant into the coolant reservoir.
Last time I encountered a situation where the coolant was depleting too quickly, I discovered a tiny pinhole in the radiator causing a slow leak. It wasn't noticeable during regular car washes, but after a long-distance trip, half the reservoir was gone. These small holes can be extremely hidden – you need to carefully inspect joints and radiator surfaces with a flashlight for crystallized water stains. If the leak is at a hose connection point, it might just be a small crack in the rubber hose, which can be fixed by replacing it for just a few dozen yuan. Actually, regularly squeezing the hoses to check for hardening or cracks is crucial, especially for older vehicles that require more frequent inspection.
