How Much Does a Coolant Temp Sensor Cost?

The only price that counts

There is no honest set price for a water temperature sensor replacement — and anyone quoting one sight-unseen is guessing with your money. On this job the figure genuinely moves with sensor versus wiring versus gauge — the diagnosis is the job; access on your engine; and coolant loss the fault may be masking. So we don’t guess: we find the actual cause first — our $374 incl. GST pre-paid diagnostic, a reserved two-hour booking with a written report, not a free quote, then you get a fixed written price for your car before any work starts. The written figure is the only number that binds anyone — hold every workshop to that standard, including us.

What drives the cost

Coolant temp sensor cost is usually modest — the part is inexpensive and access is often reasonable, though some are awkward (and may need a little coolant drained). Confirming it’s the sensor (not wiring or a thermostat) comes first.

It’s a cheap fix that can resolve surprisingly varied symptoms.

What the job involves

We read the sensor’s live data to confirm the fault, replace it, top up coolant if needed, and clear the fault — restoring correct fuelling, idle and gauge.

You get a fixed written quote once confirmed.

A fixed written price before any work

The honest answer to “how much?” depends on your exact car, parts and condition — so we inspect first, then give you a fixed written quote before we touch anything. No surprises, no scare tactics.
