Application and Buying Notes

Before ordering, compare the part number V42-99-0009 with the part you are replacing. For temperature switches and radiator fan control components, matching the number is usually the first and most reliable check, especially when the description only identifies the part as a switch and does not list vehicle models.

Because this item is listed simply as a temperature switch for radiator fan control, the vehicle application cannot be assumed from the product name alone. Check the original switch style, connector arrangement, thread or mounting details if available on the vehicle, and confirm the application through your parts catalogue or existing component before purchase.

The listed warranty is two years, and the part is supplied as each. Those details are useful when comparing replacement options, but they do not replace fitment verification. If the cooling system uses a specific thermoswitch or temperature-controlled fan circuit, make sure the replacement matches the required specification for that circuit.

If you are replacing a failed radiator fan switch, inspect the old part carefully for its markings and any other identifiers beyond the visible label. Electrical control parts can look similar across different applications, so the safest approach is to confirm V42-99-0009 against the vehicle details rather than relying on the general description alone.

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 V42-99-0009 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.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

The listed warranty is Two Years. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.
