Borgward coolant is added to the coolant reservoir, which is located near the engine. Coolant: Coolant, fully known as antifreeze coolant, refers to a coolant with antifreeze functionality. Antifreeze prevents the coolant from freezing and expanding in cold weather, which could crack the radiator or damage the engine block. However, it's important to correct a common misconception: antifreeze is not just for winter use—it should be used year-round. In regular vehicle , the engine coolant should be replaced every year. Refilling method: Add coolant through the radiator filler neck until the radiator is full. Unscrew the reservoir cap, add coolant up to the "FULL" mark, being careful not to exceed this level. Then, replace and tighten both the radiator cap and the reservoir cap.

The filler cap for the Borgward coolant is located in the engine compartment. When you open the hood, you'll see a white translucent plastic reservoir with a coolant symbol or a thermometer-like icon on the cap. I always choose to refill it in the morning when the engine is cold, as the system pressure is at its lowest, preventing steam from spraying out and injuring my hand when opening the cap. The reservoir has MIN and MAX level marks, and you should keep the fluid level between these two lines when adding coolant. A reminder to everyone: always use the manufacturer-specified type of coolant. Different colored antifreeze solutions have different chemical compositions, and mixing them may corrode the pipes. After adding, remember to start the engine and let it run for five minutes to circulate the coolant before checking the fluid level again. If the coolant level frequently drops, you should also check for any leaks in the pipes.

The location for adding coolant in Borgward vehicles is quite noticeable. Open the engine hood, and you'll find a plastic expansion tank on the front right side, marked with a COOLANT label. There are three key points to remember when performing this operation yourself: First, it must be done when the engine is cold, as opening the cap on a hot engine can cause high-temperature liquid to spray out. Second, always use Borgward's original coolant, as mixing different brands can create gel and clog the pipes. Third, the filling level should be kept between the MIN and MAX marks. After adding, I start the engine to let it warm up, and when the fan operates automatically, it indicates normal circulation. If you notice cracks in the tank or a rapid drop in the coolant level, immediately inspect the cooling system, as there might be an issue with the hoses or water pump.

The coolant expansion tank of Borgward is located on the left side of the engine compartment, which is a white container with a pressure cap marked with a radiator symbol. I check it during every service by opening the cap when the engine is cold, and feel relieved when seeing the light green liquid between the level marks. Do not exceed the MAX line when topping up, as excess liquid will expand and overflow when the engine is hot. Beginners are advised to refer to the manual to confirm the coolant type, as the mixture ratio varies by model. If the level is too low and a sweet smell is detected, it may indicate cylinder gasket damage causing oil emulsification. Under normal consumption, the level should stabilize after adding fluid and driving a few hundred kilometers. The antifreeze capability should be specially tested before winter.

The coolant filler port of Borgward is located at the front of the engine compartment. Just look for the translucent reservoir tank marked with a radiator icon. I always wear gloves when adding coolant myself, as it can irritate the skin. Before unscrewing the cap, press it to release residual pressure, and stop when you hear a hissing sound. The filling level must strictly remain within the marked range, as overfilling can cause splashing when the engine is hot. When choosing coolant, make sure it's an ethylene glycol formula, and northern car owners should also check the freezing point index. A tip: If the fluid level drops more than 3 cm per month, it might indicate a leak in the engine block or heater core. Prolonged low coolant levels can lead to engine overheating and cylinder scoring.
