BRAND NEW *OEM Quality* engine coolant temperature sensor to suit Nissan Patrol Y61 GU 3.0L ZD30DDTi.

If your GU Patrol is smoking on cold start, the temperature gauge is reading oddly, or you have a P0116-P0118 code logged, this sensor is the direct OEM replacement to fit. Same-day dispatch before 12pm from Cranbourne VIC.

TO SUIT

Covers the Nissan Patrol Y61 GU 3.0L ZD30DDTi from 04/2000 to 03/2007 and the ZD30DDTi Euro4 from 03/2007 to 12/2016, in Wagon, Cab Chassis and Pickup, manual and auto. Also fits the Nissan Caravan E25 3.0L ZD30DD and ZD30DDTi grey import. The sensor threads into the coolant passage near the thermostat housing.

FITMENT CHECK

This listing is for the 3.0L ZD30 four-cylinder only. The 4.2L TD42, 4.5L TB45 and 4.8L TB48 six-cylinder Patrols use the same sensor but are listed separately in our store. Earlier GQ TD42 engines before August 1995 run a different plug and a different sensor - check the connector before ordering.

ABOUT THIS SENSOR

The engine coolant temperature sensor is a thermistor that changes resistance as coolant temperature rises. On the ZD30 the ECU uses that signal to set injection quantity and timing, and it tells the glow plug controller when to stop cycling.

The ZD30 runs close to its thermal limits when towing or loaded, so a sensor feeding a false cold reading can mean sustained over-fuelling and rising exhaust gas temperatures. Corrosion inside the coolant system is the usual cause of failure, and these sensors can also weep coolant through the connector.

COMMON SYMPTOMS OF FAILURE

Hard cold starting or extended cranking
Black smoke on start-up and under load
Glow plug light cycling incorrectly
Temperature gauge reading incorrectly or not moving
Radiator fans running constantly or not at all
Check Engine light with codes P0116 P0117 P0118 P0125 P0128

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.
