Hyundai Santa Fe Temperature Sensors
We source temperature sensors for every Santa Fe generation sold in South Africa, then check the fit against your VIN before it leaves the warehouse

What Are Hyundai Santa Fe Temperature Sensors?
The coolant temperature sensor (ECT) tells your Hyundai's ECU the engine temperature, driving cooling fan activation, fuelling and the dashboard gauge. Across Getz, i20, i30, Accent, Sonata, Creta and Santa Fe we see this sensor fail often — a stuck-cold reading stops the fan and causes overheating.
Signs You Need New Temperature Sensors
Before you order temperature sensors for a Santa Fe
On the Santa Fe, SM, CM, DM and TM are all in circulation locally, and they do not share one parts list.Five- and seven-seat derivatives differ well beyond the third-row seat itself — floor pan, trim, glass and rear HVAC parts all follow the seating configuration.
Engine families fitted to the SA-market Santa Fe:
Air-conditioned and non-air-conditioned Hyundais take different radiators and fan assemblies, and the CRDi diesels add intercooler plumbing that the petrol cars simply do not have.
Send us petrol or diesel, and whether the car has air conditioning with your enquiry and we will confirm the correct temperature sensors against your car before anything is dispatched.
In South Africa the Santa Fe is mostly the tow car of the range, so cooling, driveline and rear-suspension components carry loads the same parts never see on a lighter Hyundai. That is the wear pattern we stock and source against.
Santa Fe Temperature Sensors: Common Questions
Will temperature sensors from another Santa Fe fit mine?
Not automatically. The Santa Fe sold in South Africa as SM, CM, DM and TM, and five- and seven-seat derivatives differ well beyond the third-row seat itself — floor pan, trim, glass and rear HVAC parts all follow the seating configuration. Send us the generation code off your VIN plate and we will confirm it either way before anything is dispatched.
Can you source temperature sensors for the Santa Fe if local stock is dry?
Usually, yes. The Santa Fe a platform relative of the Kia Sorento across several generations, which gives us a second catalogue to search when Hyundai-listed stock runs out. We will tell you what we are quoting rather than leaving you to guess.
What are the symptoms of a bad Hyundai coolant temperature sensor?
Temperature gauge jumping or stuck low, check engine light, poor fuel economy and a cooling fan that won't activate. Hard cold starts with the engine running too rich are another tell — the ECU thinks it's always warming up and keeps dumping fuel.
How much does a Hyundai coolant temperature sensor cost in South Africa?
A Hyundai coolant temp sensor (covering i10 to H1 fitment) costs around R65.93. A workshop charges maybe an hour's labour to fit. Request a free quote through our form for your specific engine — 1.4, 1.6 T-GDi and 1.6 CRDi use different sensors.
Can a faulty coolant temperature sensor cause my Hyundai to overheat?
Yes — if the sensor is stuck reading cold, the ECU never triggers the cooling fan and the engine cooks in traffic. We see this across the i20, Accent and Creta range. Replace with a revised OEM part, not a cheap generic, or the fault returns within months.
Why is my Hyundai temperature gauge jumping to red?
Either genuine overheating or a failing sensor giving false readings. Stop and check coolant level first — low coolant confirms a leak or failed thermostat. A solid cold dash on restart with no actual heat signs points at the sensor.
Can a bad coolant temp sensor cause poor fuel economy?
Yes. If the sensor reports cold when the engine is hot, the ECU keeps the mixture enriched as if still warming up. You'll see fuel consumption climb 10 to 20 percent, especially on shorter commuter trips. Replacement restores economy immediately.
