Why does the Tiguan always squeak after starting?
1 Answers
Tiguan cold start squeaking is a normal phenomenon. Due to dew and undried water from car washing adhering to the brake discs, the brake discs rust quickly. Additionally, after pulling the handbrake overnight, the sound will naturally disappear once the vehicle has run for a distance and the brake clearance returns to normal as the car warms up. The cooling system maintenance methods are as follows: 1. Check the water pump: First, visually inspect the water pump's drain hole, thermostat connection, upper and lower hose connections, drain port, radiator cap, and coolant reservoir for any signs of leakage. If leaks are found, identify the cause and address it immediately; never continue driving with the issue. 2. Check the antifreeze's freezing point: Generally, the antifreeze's freezing point should be 5 to 10°C lower than the lowest temperature in the vehicle's operating region. 3. Monitor the antifreeze level: The ideal level is about 10 mm below the radiator filler neck, or follow the standard markings on the coolant reservoir to top up with the same type of antifreeze. 4. Check the thermostat: If the thermostat is not functioning properly, the engine will operate at either too low or too high temperatures for extended periods, accelerating wear and shortening the engine's lifespan. Therefore, ensure the thermostat is in good condition.
