Car coolant can be added at a 4S shop. The types of coolant include: 1. Alcohol-based coolant; 2. Glycerin-based coolant; 3. Ethylene glycol-based coolant; 4. Propylene glycol-based coolant. The functions of car coolant are: 1. Preventing the car from freezing in low-temperature environments, which could cause the radiator and engine block to crack; 2. Preventing corrosion in the cooling system; 3. Reducing the formation of scale during circulation; 4. Absorbing heat to ensure the radiator can withstand high temperatures without boiling. Precautions for using car coolant are: 1. Prevent coolant leakage; 2. Coolant is toxic, so avoid ingestion; 3. Coolant is flammable, so take precautions against fire when using it.

I've been driving for over twenty years, and when it comes to adding coolant, the first thing to mention is the location: it's in the engine bay, look for that translucent plastic reservoir, usually labeled 'Coolant' or 'COOLANT.' Before you start, make sure the car has completely cooled down for at least half an hour—opening the cap when it's hot can release steam and cause serious burns, which is really dangerous. Open the cap slowly, and don't pour too quickly to avoid overflow; just fill it up to the MAX line. Use dedicated coolant mixed with distilled water, and never add tap water randomly to prevent rust or freezing. Personally, I check the coolant level every quarter—if it's low, top it up to prevent overheating in summer and freezing in winter. If you don’t drive often, I recommend checking it monthly, as high engine temperatures can cause serious damage over time. It’s a simple little maintenance task, but making it a habit can save you big on repair costs.

As an average car owner, I always top up at the coolant reservoir. There's that translucent plastic tank in one corner of the engine bay for easy fluid level checks. Always turn off and cool the engine first before operation - the cap has warnings against opening when hot. Use a funnel for slow pouring during refill, and don't exceed the MAX line. I prefer buying premixed coolant for convenience. Locations vary slightly by vehicle - my SUV's reservoir is on the left side, while compact cars may have it up front. If unsure, check the manual or search for vehicle-specific diagrams online. Regular checks are crucial, like doing it during oil changes to avoid coolant leaks on long trips. Coolant plays vital roles in heat dissipation and corrosion prevention - never cheap out with counterfeit products. Keep the engine bay clean to prevent debris from covering the reservoir.

I think adding coolant is simple yet crucial. Locate the plastic reservoir tank in the engine bay, usually near the firewall with a transparent wall showing the fluid level. Only proceed when the car is cold, and slowly add the matching coolant. Never mix different types like red and blue, as it can cause blockages. Once, I neglected to check and ended up with low fluid causing engine overheating and a tow truck—a hard lesson learned! Keep a small bottle handy for emergencies, and always check the fluid level when parked; if it's too low, there might be a leak requiring pipe repairs. The location isn't mysterious—common models like Volkswagen or Toyota place it at the rear right side of the engine. Beginners can easily learn from YouTube tutorials. Also, consider seasonal effects: check the antifreeze rating before winter, and watch the boiling point in hot weather. Safety first—wear gloves to prevent splashes.
