How do I know if this Gauge Temperature Sensor fits my Vanagon?

This temperature sensor is designed specifically for 'late' Vanagons, covering model years 1986, 1987, 1988, 1989, 1990, and 1991 with water-cooled engines. Before you buy, check the plug shape on your original sensor—this fits models with a spade (flat blade) connection, not the earlier round pin design. If you have a 1986 or later Vanagon with the flat spade connector, this is the sensor you need.

Do I need any additional parts to install this temperature sensor?

Yes, you'll need a new o-ring to ensure a proper, leak-free seal during installation. You can usually reuse your old sensor clip, but many customers order a fresh o-ring just for peace of mind. Make sure to have one on hand when you're swapping out your old sensor.

How can I be sure this is the right temperature sensor for my Vanagon?

It's always best to double-check your existing sensor before ordering. Remove your old sensor and compare its plug style and shape—this one is for the later, flat spade plug. If your Vanagon is from 1986-1991 and uses the spade connector, this replacement will fit. If you're unsure, take a photo of your connector and contact our support for confirmation—we're happy to help!

Is this an OEM part, and can I trust its quality?

This is a high-quality aftermarket replacement temperature sensor designed to match OEM specifications for late-model Vanagons. It's thoroughly tested for reliability and fitment. We stand behind all our products—if you have any fitment or performance concerns, our support team is ready to assist you.

What else should I check before ordering to avoid mistakes and returns?

Make sure to check: 1) Your Vanagon's model year (this part is for 1986-1991 only), 2) The plug/connector shape (flat spade, not round pin), and 3) That you're ordering an o-ring along with the sensor. Comparing your current sensor with the product photo is always a good idea. If you have any questions or doubts, reach out to us before you order. We want to make sure you get the right part the first time!
