ACDelco Gold 213-4792 (88865045) Engine Coolant Temperature Indicator Switch

Was a replacement for my v6 boat

went right in and direct fit for my 75 3/4 454 suburban. mine has the single spade wire connector. there is a second design with a round pin so it could be either or

Works

I bought this on the description given by the Amazon website. It says it is a switch with normal open contacts.My intention was to wire it to just an over temp indicator light. When the engine came up to temp, my light justbarely glows, so I measure the so called switch with an ohm meter to ground to find 1000 ohms to ground afterthe engine had cooled down some. So this must be a sensor, not a switch !!! This could be why it has many returns !

Came ready to install with thread sealant already on it.

The product did not fit my 55 Thunderbird so I returned and they refunded my money. Thanks

This is a OEM AC Delco temperature switch. For those like me who are interested in it for generic applications; when I tested it in a pot of water on the stove with a cheap thermometer the switch closed and reopend when the water temperature crossed about 185 degrees Farenheit.

It was advertised as correct sensor the my Chevrolet motor and when I tried to screw it into my motor it was the wrong size threads and would not mate to the engine block
