BRAND NEW *OEM Quality* engine coolant temperature sensor to suit Subaru Liberty, Outback and Forester with EJ25 and EZ30 engines.

On these Subarus the usual complaint is a gauge that sits low, fans that will not settle, and fuel use that has crept up over a year or two. A new sensor puts the readings back where they belong. Packed and shipped from Cranbourne VIC.

TO SUIT

Fits the Subaru Liberty BE, BH, BL, BP and BR, the Outback BH and BP including the H6, and the Forester SF, SG and SG9. Covers the EJ25, EJ251, EJ255 and EJ25DET four cylinder engines and the EZ30 flat six.

FITMENT CHECK

This is the 3-pin triangular plug with an M12 x 1.5 thread. Some rows in our application data are restricted to the EJ251 only, so confirm your engine code if you have a 2.5 litre Liberty or Outback.

ABOUT THIS SENSOR

On the EZ30 flat six the sensor is buried behind the intake and rarely gets inspected, so a slow drift can run for years before anyone connects it to the fuel bill. The four cylinder EJ25 is easier to reach but sees the same heat cycling.

These are family cars that do a lot of short trips, which means the warm-up map runs more often than it does on a highway car. A sensor reading cold therefore costs more fuel here than the same fault would elsewhere.

COMMON SYMPTOMS OF FAILURE

Fault codes P0115, P0118, P0125 or P0128 stored
Temperature gauge slow to rise or sitting below normal
Fuel economy worsening with no other fault found
Cooling fans running from a cold start or not engaging at all
Rough idle and hesitation until fully warm
Heater slow to produce hot air

How do I test a coolant temperature sensor?

The most common test is to measure the sensor resistance with a multimeter at a known coolant temperature and compare against the manufacturer resistance curve. A cold engine (20 degrees C) typically reads 2,000 to 3,000 ohms and drops to around 200 to 300 ohms at operating temperature (90 degrees C). An OBD2 scanner showing a fixed temperature reading that does not change as the engine warms up is also a strong indicator of sensor failure.

Can a faulty coolant temperature sensor cause my engine to overheat?

Indirectly yes. If the sensor reports a lower temperature than actual, the ECU may not activate the cooling fan at the correct time, allowing the engine to overheat. It can also suppress the dashboard warning light, meaning you may not be alerted until the engine is already at a dangerously high temperature. Replace a suspected faulty sensor promptly.

Do I need to drain the coolant to replace the sensor?

Not always - many coolant temperature sensors can be replaced quickly with minimal coolant loss if you work fast and have a replacement ready to thread in immediately. However on some vehicles the sensor location requires partial coolant drainage. Check the sensor position on your specific engine before starting. Always use fresh coolant when topping up after replacement.

What are the symptoms of a faulty coolant temperature sensor?

Symptoms include poor fuel economy, black smoke, engine overheating warning, incorrect temperature gauge reading, hard starting when cold, and rough idle. Fault codes P0115 to P0119 are commonly associated with coolant temperature sensor faults.

Is it safe to drive with a bad coolant temperature sensor?

A faulty coolant temperature sensor can cause the ECU to run rich fuel mixtures and prevent the cooling fan from operating correctly, risking engine overheating. Replace it promptly - it is a low-cost part that can prevent expensive engine damage.

How do I know if my coolant temperature sensor or my thermostat is faulty?

A faulty thermostat typically causes the engine to overheat or never reach operating temperature. A faulty coolant temp sensor causes incorrect gauge readings and running issues but the coolant itself may be at the correct temperature. An OBD2 scanner showing live coolant temp data helps distinguish between the two.

Are there two coolant temperature sensors on my vehicle?

Many vehicles have two sensors - one for the ECU (engine management) and one for the dashboard temperature gauge. They look similar but are not interchangeable. Check your vehicle's service manual or contact us with your vehicle details to confirm which sensor you need.
