Why does the Tiguan always squeak after starting?
1 Answers
Tiguan's cold start squeaking is a normal phenomenon. Due to dew or undried water from car washing adhering to the brake discs, the discs rust quickly. Additionally, after leaving the handbrake engaged overnight, the sound will naturally disappear once the vehicle has run a certain distance and the brakes have warmed up, returning to normal clearance. The cooling system maintenance methods are as follows: 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 leakage is found, identify the cause and address it immediately; do not continue driving with the issue. 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. Monitor the antifreeze level: It should be about 10 mm below the radiator filler neck, or refill with the same type of antifreeze according to the standard marks on the coolant reservoir. Check the thermostat: If the thermostat is not functioning properly, the engine will operate under prolonged low or high temperatures, accelerating wear and shortening its lifespan. Therefore, ensure the thermostat is always in good condition.
