Will it fit my Mazda MX 5?
Increasingly sold as a full housing unit with an integrated sensor on newer engines — check whether yours is thermostat-only or housing-and-all.
Tip: filter by your reg on eBay's compatibility check, or match the part number stamped on your old unit.
Signs your Mazda MX 5 thermostat needs replacing
- Temp gauge slow to rise or overheating
- Poor heater performance (stuck open)
- Overheating in traffic (stuck shut)
- Coolant warning light
Fitting it yourself
Usually a housing with 2–3 bolts and a coolant hose — straightforward, but refill and bleed the cooling system properly after.
