Product Description

The Arrowhead Thermostat Seal 45x53x4mm is designed to maintain a secure, leak-free seal in your vehicle’s cooling system. This seal is essential for keeping coolant contained within the thermostat housing, helping to regulate engine temperature efficiently. Made from durable rubber material, it is shaped to fit precisely in the specified housing dimensions.

This thermostat seal is compatible with selected Audi, Seat, and Volkswagen models that require a 45x53x4mm seal size. It is commonly used in models fitted with 1.4 TSI or TFSI engines, as well as certain 1.6 and 16V engine variants. Always confirm your vehicle’s model, year, engine size, and engine code to ensure correct fitment before ordering.

A faulty or worn thermostat seal can lead to visible coolant leaks around the thermostat housing, engine overheating, erratic temperature gauge readings, and low coolant levels. You might also notice a sweet smell from leaking coolant, or steam coming from the engine bay. In some cases, persistent leaks may trigger warning lights on your dashboard.

Replace the thermostat seal whenever you notice signs of leakage, during thermostat replacement, or as part of routine cooling system maintenance. Timely replacement helps prevent coolant loss and potential engine damage due to overheating.

Order your Arrowhead Thermostat Seal from MiMi Auto Parts for reliable fitment and peace of mind. We offer nationwide delivery across South Africa, and our team is ready to assist you in finding the right part for your vehicle.
