My DJ with l head engine has a brass bushing on the head that my electronic sensor screws into. Does this adapter replace that bushing if I change over to a mechanical temperature unit

Willys Jeep Parts Tech:
Please email more info and year on your DJ. But it sounds like you have 914777 and 905926

After installing this bushing into the engine block, does the sensor probe from the gauge compress down into the bushing creating a seal so as to not have coolant leak out?

Willys Jeep Parts Tech:
The fitting on your gauge will make the seal once tightened down with the prob.

Would this fit your your after market water pump for a m38a1?

Willys Jeep Parts Tech:
This is for your temperature gauge if you have the earlier style gauges used on MB/CJ-2a ect. You are looking for part number: 7372808 or 7372810.

I have a 52 cj-3A the water temp sensor on the motor is an electrical sensor with a 14 inch thread will the adapter bove fit this application for the mechanical one you sell. Do you sell Stewart Warner stand alone gauges

Willys Jeep Parts Tech:
647886 is what you should have installed on the CJ-3A. The A3557 is required for it.
