Volkswagen Beetle coolant leak on passenger side after serpentine belt replacement on Volkswagen Beetle

Some Volkswagen Beetle owners report experiencing coolant leaks on the passenger side after replacing the serpentine belt, which may be connected to the belt replacement process. These leaks could be attributed to disturbances in the coolant pump, which is often affected during the serpentine belt replacement, potentially leading to coolant leakage. Additionally, issues with coolant lines that run through the front passenger side may cause puddles of coolant to form on the ground. Owners are advised to look for bluish fluid with a sweet smell or signs of coolant on the passenger side control arm or serpentine belt pulley as indicators of a leak. Furthermore, a rusty color in the coolant can signal a leak that requires immediate attention. If the source of the leak remains undetermined, using a cooling system pressure tester may help locate the issue. Promptly addressing these coolant leaks is crucial to prevent further damage to the vehicle's engine and cooling system.
