Keep the radiator cooling fan switching on when the engine needs it with the Standard Ignition Engine Cooling Fan Module / Engine Cooling Fan Motor Relay (RY-437, also written RY437) — a direct-fit vw Jetta cooling fan relay that also drops into the 1995-2002 Volkswagen Cabrio and 1995-1997 Volkswagen Passat. It replaces the original relay for the 1993-1998 Jetta [All, L4-1.9L, L4-2.0L], 1993-1995 Jetta [L4-1.8L], and 1994-1998 Jetta [V6-2.8L]; the 1995-2002 Cabrio [All, L4-2.0L]; and the 1995-1997 Passat [All, L4-1.9L, V6-2.8L] plus 1995-1996 Passat [L4-2.0L].

  • Switches the cooling fan circuit: handles the control signal that energizes the engine cooling fan motor.
  • Direct-fit replacement: installs in place of the factory relay/module on the listed Volkswagen applications.
  • Addresses a failed relay: if a worn cooling fan relay is the cause of a fan that won't run or runs constantly, this replaces it.

Signs the original relay may need replacing include a cooling fan that never engages, runs nonstop, or cycles erratically — diagnose the circuit first, since these symptoms can have other causes. Listed as both an Engine Cooling Fan Module and an Engine Cooling Fan Motor Relay.

Frequently Asked Questions

Will this fit my vw Jetta relay location?

Yes, RY-437 fits the Volkswagen Jetta in L4-1.8L (1993-1995), L4-1.9L and L4-2.0L (1993-1998), and V6-2.8L (1994-1998). Check the Buyer's Guide tab to confirm your exact year and engine.

Is this a Passat relay too?

Yes. It fits the 1995-1997 Volkswagen Passat [All, L4-1.9L, V6-2.8L] and the 1995-1996 Passat [L4-2.0L], in addition to the Jetta and Cabrio applications listed.

What does this cooling fan relay do?

It switches the control circuit that powers the engine cooling fan motor, allowing the fan to turn on and off as commanded rather than carrying that current through a switch directly.

My cooling fan runs constantly — is the relay bad?

A stuck relay can keep the fan running, but so can other faults in the circuit. Diagnose the cause first; if the RY-437 relay is confirmed faulty, this replaces it.

Does this Jetta relay come as one unit?

The listed applications each use one relay. This listing supplies the Standard Ignition RY-437 module/relay for the covered Volkswagen Cabrio, Jetta, and Passat models.
