SWITCH THERMO 10 C PREHEAT (Crown CR65.27435-6003)

A damaged thermo switch can disrupt preheat timing, leading to hard starting in cold conditions. This aftermarket replacement part references Crown as the OE maker and carries the cross-reference number CR65.27435-6003. The switch type is a thermo switch, which opens or closes an electrical circuit based on temperature. Its plain mechanical function is to sense ambient or coolant temperature and trigger a preheat cycle. A concrete generic failure consequence is that a stuck-open switch may prevent the preheat circuit from activating, causing extended cranking. Keeping a thermo switch in sound condition helps ensure reliable cold-start performance. Verify the serial number or application, then call (562) 693-7748.
