Is the GoWesty Audible Coolant Temp Alarm Kit compatible with my Vanagon, and does it work if I have aftermarket upgrades?

Yes! The GoWesty Audible Coolant Temp Alarm Kit is specifically designed for all water-cooled 1982–1991 Vanagons, covering every drivetrain, transmission, and model. It's also fully compatible if your van uses GoWesty’s Printed Circuit Board Replacement Kit, and it works seamlessly with most common aftermarket upgrades. As long as your original coolant warning system is functioning, this kit will enhance your van's protection—no special modifications needed.

How hard is it to install the Coolant Temperature Alarm Kit, and will I need to modify my Vanagon?

Installation of this kit is quick and straightforward, with no permanent changes or modifications required to your Vanagon. The package includes detailed instructions and there’s also a YouTube video to guide you step-by-step. Most Vanagon owners report that they easily installed the kit themselves, gaining added confidence and peace of mind without needing professional help.

What makes this audible coolant temperature alarm more effective than relying on the factory warning system alone?

The GoWesty Audible Coolant Temp Alarm Kit doesn’t replace your factory warning system—it works with it by adding an immediate, clear audible alarm the moment the red coolant warning light comes on. That means if your engine temperature gets too high or your coolant is low, you’ll hear an instant alert, helping you avoid costly engine damage. Many owners love the extra layer of protection, especially since the factory warning light can be easy to miss in bright sunlight or while driving.
