What to do if your Subaru coolant gauge is not working?

What to do if your Subaru coolant gauge is not working?

Check the fans are cycling properly and for proper operation of the thermostat. Next you need to read the coolant temperature sensor and if you have a scanner it makes it easy but if not, no worries you can just jump straight to the test you would have to do if you were having coolant temperature sensor problems anyways.

What kind of temperature sensor does a Subaru Outback have?

Now most vehicles use a two-wire temperature sensor and a one-wire sender that would be for the gauge. The other two-coolant sensor is for the computer. Subaru uses one dual function sensor so you will see a three-wire sensor.

What makes up the air conditioning system in a Subaru?

Typical Subaru Air conditioning Problems explained. The Air conditioning (AC) system in your Subaru is made up of the following. A compressor, Condenser, Evaporative (Evap) core, Expansion valve, receiver dryer, hoses and lines, thermo sensor and the controls.

Why does my Subaru air conditioner shut down?

So, the radiator kept the engine safe, but when the fans were kicking on, they were blowing A LOT of hot air at the evap unit. That would trip the AC temp sensor and shut down the AC. Yes that will happen if the radiator is clogged enough to limit air flow, thus not allowing the proper temp drop needed to take the heat out of the AC system.

Why is the fuel gauge on my car not working?

Some fuel gauges have an analog display while others have a digital or liquid crystal display. Electronic and software malfunctions may cause the fuel gauge in your automobile to inaccurately measure or display the amount of fuel remaining in the gas tank. If this happens, reset your fuel gauge.

Where is the three wire gauge on a Subaru?

Subaru uses one dual function sensor so you will see a three-wire sensor. They share a common ground and the other two wires are volt references to the gauge and PCM. Find the three-wire sensor in the water crossover pipe under the intake manifold, just right of center.

Why does my gas gauge keep pegging full?

The gas gauge might interpret voltage feedback from a dead sender as FULL or EMPTY, consequently pegging the gauge no matter the actual fuel level. Circuit Problems can cause the gas gauge to stop functioning normally.

How much does a Subaru coolant sensor cost?

You should be able to get a gauge from the Subaru dealer for less that $30.00 and the sensor is a little more expensive but either way this can be a relatively inexpensive fix that can prevent costly engine damage from not having a properly working coolant gauge. Well, that’s about it.
