GW Coolant Level Sensor vs Aftermarket Coolant Level Sensor

[SoquelDude]

Hi!

My coolant sensor is dust, so I need to replace it. I wanted to see what folks felt about the GW sensor. How reliable is it? ANy problems using it with the original, plastic expansion tank?

Thanks!

I have the GW sensor and it has worked without issue for over a year.

My recent new plastic tank lasted 13 months and cracked.

If your coolant reservoir is over on the right side of your engine, you may like SmallCar's aluminum tank.

I modded an old cracked original VW sensor and a NEW URO////Parts sensor. Pics.here.
The mod has only been tested a few weeks though.

The brand of the tank matters if we want to understand data.

I've been mounting Febi tanks with great success the last few years.

OK, I did some troubleshooting today. I cleaned the sensor probes and electrical connector.

However, I noticed the expansion tank was 2/3 full. From all of the topics posted about the expansion tank, I was under the impression that the tank should always be full. So, I topped off the coolant in the tank and started the engine.

The level LED started blinking as before, so I'm convinced the sensor is bad. However, what would cause the drop in coolant level in the expansion tank. I saw no signs of a leak, and I can't believe a bad sensor could cause this. DO I need to bleed the coolant lines?

Pull the plug off the sensor.
Put a jumper across the plug (from socket to socket).

Does the LED stop blinking?

If the paper clip doesn't trigger the light to NOT come on, then it's an instrument cluster printed circuit issue or a break in the wiring.
Check the ground wire at the connector is actually grounded, then
with the jumper on, just check continuity on the opposite end of the wiring harness dashboard side to ground. That'll take care of the harness. Once that is good, you're onto the next step...

I recall you have to cycle the key once the led is flashing. So with the switch harness jumped, be sure to have the key in the off position.
