Mazda MX5 Mk1 Cooling & Heating
Running hot in traffic or losing heat on cold mornings? A fresh MX-5 Mk1 radiator sorts most overheating issues, and it's one of the most requested items in our MX-5 Mk1 parts range for the NA roadster.
Radiators, Pumps and Thermostats
An ageing MX-5 Mk1 radiator loses efficiency long before it visibly fails, so swapping it alongside the water pump and thermostat gives the engine a proper reset. Top up with fresh coolant and the correct grade of Mazda MX-5 engine oil while you're at it, since both jobs are usually done together.
The heater matrix is worth checking too if the cabin's blowing cold, and our drive belts keep the water pump and alternator turning as they should. A clogged radiator often points to a tired filtration system, too, so it's worth checking that at the same time.
If your fan isn't cutting in as it should, the fault usually lies with the electrical system rather than the cooling parts themselves. Call 01522 568000 for help identifying the right MX-5 Mk1 parts for your cooling system, or browse our service kits to bundle cooling work with routine maintenance.
