This is an electrical part in the engine management group, and it is intended for applications identified as CITROEN and PEUGEOT, including Citroën BX, Citroën CX, Peugeot 205 and Peugeot 505 references in the fitment data. As with any temperature switch, the important check is whether the vehicle calls for the same part number and matching temperature range before ordering.

The listed description is radiator fan switch P205/505, so the part identification matters just as much as the vehicle family.

Application and Buying Notes

Before buying, check the old switch and the vehicle application against part number 819770 and the stated temperature range. The important figures here are 87°C to 92°C, with an additional listed shut-off point of 88°C and switch point to 83°C, so it should only be used where those values match the original requirement.

This type of part is often selected by the cooling system calibration rather than by a general model name alone. A Peugeot 205 or Peugeot 505 listing in the fitment data is useful, but it is still best practice to compare the original part details, because radiator fan switch specifications can vary between engines, model years and cooling package combinations.

If you are replacing a failed switch, inspect the old unit for the stamped number or any matching reference before placing the order. Valeo 819770 is the key identifier provided here, and using that alongside the vehicle application is the safest way to confirm you are choosing the correct switch for the car.

Because this is a switch sold each, the purchase is for the component itself rather than a kit or assembly. Make sure the replacement matches the original electrical part type and the engine management application, and avoid relying on the vehicle badge alone if the existing switch differs in temperature setting or part reference.

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 819770 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.
