638752 INA Thermostat Housing, Water Pump & Belt Kit 113°C – 1.8/2.0 FSI

INA Thermostat Housing, Water Pump & Belt Kit – 1.8/2.0 FSI/TFSI/TSI Engines

This is a complete OEM-quality cooling system service kit from INA, one of the VAG group's preferred suppliers. The kit includes the thermostat housing, water pump, and drive belt — everything needed for a full cooling system refresh in one box.

Kit includes:

• Thermostat housing (opens at 113°C)
• Water pump
• Drive belt

⚠️ Fitting Note
This is not a quick job. Allow approximately 6 hours of labour time for a full installation. Factor this into your total cost when comparing prices — a cheap part that fails means paying for the labour twice.

Why not just buy cheap?
We understand the temptation. But inferior thermostat housings and water pumps are a common cause of coolant leaks, overheating, and in worst cases, engine damage on these engines. The labour cost alone makes a failed cheap part an expensive mistake. This kit uses genuine-quality components built to VAG specifications — buy it once, fit it right.
