What does the temperature gauge on a Vanagons mean?
2) Engine temperature exceeding about 15/16ths on the gauge. The coolant temperature sensor is a variable resistor. Its resistance DECREASES as the temperature INCREASES. If you unplug the wire (s) from the sensor, the gauge should read cold.
Where is the coolant level sensor on a Vanagons?
When troubleshooting, check the two wires going to the coolant level switch in the pressure tank. Remove the plug on the level sensor, and make sure that brown wire is providing a ground path to the sensor.
What’s the coolant level on a Vanagon expansion tank?
The Expansion Tank also has a built-in coolant level sensor, which detects a low fluid level and triggers a flashing red warning light in the dashboard temperature gauge. This same warning light may also be triggered by separate coolant temperature sensors, located elsewhere.
Where is the engine located in a Volkswagen Vanagon?
Most water-cooled cars, including the one you probably use as a grocery-getter, has the engine up front, right behind the radiator. So, the entire drivetrain is in one compact package. Like all previous Volkswagen vans, the Vanagon/Transporter’s engine is located in the rear of the vehicle.
Why is the temperature light blinking on my Vanagons?
If you touch the wire to ground, the gauge should peg and the light should flash. During your tests, if the blinking light is ever activated, remember that you need to reset the system by turning the key to the off position. If it passes this test, you know the wiring and gauge are working properly, and you might have a bad temperature sensor.
When does a Vanagons fan come on at a higher speed?
In that case, if the temperature gets up to 95°C (203°F), the fan comes on at a higher speed (loud!). This all happens at a temperature gauge reading of about 7/8. This is also normal, but start paying close attention.
