Why should I upgrade my Vanagon's coolant level sensor with this kit?

The original coolant level sensors and many aftermarket replacements are made of plastic and are prone to developing leaks over time. Our GoWesty Coolant Level Sensor Conversion Kit features a durable, all-metal sensor and a thread adapter, designed to eliminate the risk of leaks and provide a reliable, long-term solution for your Vanagon's cooling system. It's a simple way to protect your van and ensure peace of mind.

Is this coolant sensor kit difficult to install on my Vanagon?

This kit is designed for a straightforward installation. It includes a new all-metal sensor and a thread adapter with an O-ring for a direct fit into either your original plastic expansion tank or our aluminum one. You will need to delete the original wire connector and crimp on the new weatherproof plug that's included. Full PDF instructions are provided to guide you through the process, making it a manageable DIY upgrade.

Will this GoWesty coolant sensor kit work with my specific Vanagon year?

Yes, this Coolant Level Sensor Conversion Kit is designed to fit Vanagon models from 1983 through 1991. It directly replaces VW part numbers 251-919-372 and 251-919-372A, ensuring compatibility with the cooling system of these Vanagon years.

How does the all-metal sensor in this kit prevent coolant leaks compared to the original plastic ones?

The original plastic coolant level sensors and many reproductions often develop leaks because the plastic can become brittle or warp over time, especially with temperature changes. Our kit uses a modern, all-metal sensor that is inherently more resistant to degradation and expansion/contraction issues. Combined with the new thread adapter and O-ring, it creates a much more secure and leak-proof seal within your Vanagon's expansion tank.
