Is this Oil Pressure Switch - Low Blue compatible with my Vanagon?

Yes! This Oil Pressure Switch - Low Blue (part number 028-919-081D) fits all 1983–1991 VW Vanagon models, including both 2WD and 4WD versions with any body or transmission type. If you drive a Vanagon from these years, this switch is designed specifically for your vehicle.

Where is the Oil Pressure Switch - Low Blue located and how do I access it?

This oil pressure switch is conveniently located on the driver's side of the engine, between the intake push rod tubes for cylinders 3 & 4. Its blue color makes it easy to spot when you're working in the engine bay. Most DIY mechanics find replacement straightforward with basic tools—just remember to disconnect your battery and relieve oil pressure for safety.

How does the Oil Pressure Switch - Low Blue function, and why is this important for my Vanagon?

The Oil Pressure Switch - Low Blue is a normally closed circuit that opens between 0.15–0.35 BAR (2–5 PSI), alerting your Vanagon's warning system if your oil pressure drops too low. This helps prevent engine damage by warning you of possible lubrication problems before they become serious issues. Reliable oil pressure monitoring is crucial for engine longevity.

How do I know if this is the right oil pressure switch for my Vanagon year and model?

For 1983–1985 Vanagons, this is the only oil pressure switch you need. For 1986–1991 models, it's one of two required switches. Always double-check your Vanagon's year and refer to the location (driver’s side, by push rod tubes for cylinders 3 & 4) for confirmation. The blue color and part number 028-919-081D also help ensure proper identification.

Is the Oil Pressure Switch - Low Blue a high-quality, reliable part?

Absolutely! This oil pressure switch is a quality aftermarket part, highly rated by GoWesty customers for its fit and function. It’s designed to meet OEM specifications, ensures dependable oil pressure monitoring, and is easy for both first-time and experienced Vanagon owners to install with confidence.

Oil pressure switches fixed the problem

My 91 Vanagon uses 2 of these. I replaced both and it fixed the lack of power while accelerating and oil light buzzing issue. This one goes under the engine on the driver side. The other, which is gray, goes below the water pump pulley.

Gowesty is a life saver for these vanagon!! Always making new items. Great about sharing there tech skills! The lower temp sensor works great! I would definitely recommend Gowesty to anyone with a vanagon! Thank you for all the help your business shares! Most of us are doing the work our selves now days,as most shops prioritize the newer easier jobs!

this appears to be of high quality; I'm in the process of finishing my upgrade to the cooling system. I bought to replace the current sensor while everything is apart, and I can get to it. I don't want to replace this on the road.

Arrived fast and was a perfect fit

Great quality just what I needed

Easy Install

Need 24 mm deep socket. Just take off the cover and the torque spec is like 22 ft-lbs.

Works alright, easier to deal with than the original

I was hoping replacing this sensor would magically reveal that my low oil pressure problem was a non-problem, but it did not. But at least I know I've got a proper alarm and can move on to the next step of trouble shooting. This sensor is also much easier to install/remove than the chunky plastic brown one that was installed originally.
