Application and Buying Notes

Before ordering, check that your replacement switch matches part number OFS42 and is intended for the same electric thermo fan application. A thermatic fan switch is not a generic universal item, and the correct application matters just as much as the brand name.

The supplied fitment information covers several Ford and Mazda applications, including Capri, Festiva, Laser, Meteor, 121, 323, 626 and 929 variants. Use the exact vehicle details, including model and year where listed, to confirm the switch is suitable for your car.

The warranty is stated as two years, with the feature information also referring to a 2 year / 40,000 km warranty. That gives a clear coverage reference, but it does not replace checking the part number and vehicle application before fitting.

If the cooling fan issue is being diagnosed, remember that a fan switch is only one part of the system. A correct switch can only do its job if the rest of the electrical circuit and the fan assembly are in suitable condition, so it is worth verifying the full setup before purchase.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number OFS42 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Compatibility note: Please confirm compatibility by matching part number OFS42 and the exact vehicle application details before ordering. Fitment should always be checked against the specific model, year and cooling system configuration.
