What does G13 coolant mean?
2 Answers
G13 coolant is the latest model of Volkswagen's original coolant, fully compatible with G12 and G12+, and contains propylene glycol. Below is relevant information about coolant: 1. Definition: Coolant prevents the freezing of the liquid in the cooling system during cold winter parking, which could otherwise crack the radiator and damage the engine cylinder block. 2. Function: It provides anti-corrosion protection for components of the cooling system. It prevents scale buildup, avoiding reduced radiator efficiency. It ensures the engine operates within the normal temperature range. It must have characteristics such as anti-freeze, anti-boil, anti-corrosion, anti-scale, and be foam-free, unaffected by seasons or regions.
Hey, I've been using Volkswagen cars for many years. G13 coolant refers to a specific type of coolant model recommended by brands like Volkswagen and Audi, meaning it meets the specific design standards of those cars. Simply put, it's a liquid mixed with ethylene glycol and additives to protect the engine from freezing and cracking in winter and from overheating in summer. When I had my first car, I mixed it with the older G12, and the water pump rusted through, costing a fortune to repair. Now I always buy the pink G13, changing it every two or three years, checking the fluid level and whether the color has faded during inspections. Regular maintenance is simple and hassle-free. Coolant also prevents corrosion and rust in the pipes, extending the lifespan of the parts. If you drive a similar model, I recommend sticking to the original factory specifications to avoid compatibility issues and ensure driving safety. Doing it yourself is also easy—just buy it online or from a specialty store, and don't go for cheap off-brand options.
