The reasons for overheating: Common causes of engine overheating or even "boiling over" include damage to electronic components in the cooling system (thermostat, cooling fan), poor radiator heat dissipation, insufficient coolant, etc. Here are the related details: Solutions: Check if the lack of antifreeze is causing the engine to overheat, and inspect the coolant circulation for any blockages. Additionally, you can examine the water temperature sensor, water pump, thermostat, and cooling fan, as any of these could lead to overheating. If these issues are present, it is recommended to visit a repair shop immediately for maintenance.

How often should the spark plugs of Volkswagen Touran be replaced?

Volkswagen Touran spark plugs need to be replaced every 25,000 kilometers or 18 months. If the spark plugs are not replaced for a long time, it may cause issues such as leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most importantly, difficulty in ignition, affecting the normal use of the vehicle. Spark plug replacement cycle: Under normal maintenance conditions, spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is recommended to follow the user manual. The following standards can be used as a reference for maintenance replacement: platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Steps to replace spark plugs: Open the hood, lift the engine's plastic cover, remove the high-voltage distributor wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are cleaned thoroughly. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the removed high-voltage distributor wires in the correct firing order and secure the cover back in place.
