Coolant Temp Sensor for Ford F100 F150 F250 F350 V8 4.9L 5.8L 302 351 6810428

BRAND NEW *OEM Quality* engine coolant temperature sensor to suit Ford F100 F150 F350 V8 4.9L and 5.8L 302 & 351 models.

A drifting coolant temperature reading can throw off fuel trim and idle quality on these engines, showing up as hard starting, black smoke or an illuminated Check Engine light. This direct-fit replacement restores accurate readings so the ECU can do its job. Same-day dispatch from Cranbourne VIC.

TO SUIT

Direct fit for the Ford F100, F150 and F350 V8 4.9L 302 and 5.8L 351 Windsor/Cleveland engines across the RWD and 4WD Standard Cab, Ute and Chassis Cab range. See the full engine/year breakdown further down this listing.

FITMENT CHECK

F250 is included in this listing's title for search purposes, but F250 does not appear in our AU-market application data - only F100, F150 and F350 are AU-confirmed. If you're fitting to an F250, please confirm against your OEM number before ordering.

PACKAGE INCLUDES

1 x OEM Quality Engine Coolant Temperature Sensor (2-pin round plug, 24mm spanner size, 3/8"-18 NPTF thread).

ABOUT THIS SENSOR

On these V8 Windsor and Cleveland engines a failing sensor commonly shows up under load or towing, where an inaccurate reading can push the engine into an over-rich fuel map and noticeably hurt fuel economy on a heavy-duty pickup.

Replacing it restores correct fuelling and idle behaviour and is a common, low-cost fix on these older US-sourced V8s.

COMMON SYMPTOMS OF FAILURE

Check Engine light illuminated
Poor fuel economy, especially under load or towing
Black smoke from the exhaust
Rough or unstable idle, especially when cold
Engine overheating or an inaccurate temperature gauge
Difficulty starting when the engine is cold

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.
