CCEGR Radiator Vacuum Switch

The number 3830981 is an identification number, not the Chrysler catalog number. 3837622 is the correct Chrysler catalog part number. If you want one that looks like the original switch, you will have to find a good used one. All the replacements, including Chrysler 3837622 do not look like the original switch but function the same. The replacement switches appear to have 3 vacuum ports, but the center one is just a locating stud used on some models. The switch is activated when the temperature reaches 60 to 65 degrees. Examples can be seen by searching eBay with the number 3837622.
