Anything special to removing the temperature sensor on a 425? I would like to install a tell-tale guage to replace the idiot light.

 

That's the oil pressure sensor, isn't it? The temp sensor is on the intake.

 

The temp sender comes off with the correct sized hex socket.

The oil sender (pictured) comes off with a special socket available at many local auto parts stores.

 

How do I ask for that socket?

 

To tell the truth, I've always just used a wrench. Even a crescent wrench, if you can get the jaws in there.

"Oil pressure switch socket"


If they scratch their heads on that one, then they should not be in that business...

BTW, the size is pretty universal. The one I got for use on my Ford 20 years ago fit the one on my 72 Olds.

 

I should have guessed!

 

Here's a pic of my universal oil pressure switch tool.

They come in left and right hand so you have make sure you get the correct type.

 

but can I get one in metric?

 

They do not come in left-handed models, that's for sure.
I complained to the Vice Grip company and threatened to sue for discrimination on left-handed folks...

 

I bought one of those oil pressure switch sockets. It works great.

 

Southpaw huh??

Maybe in The Land Down Under the universal wrench is metric, upside down and backwards??...have to ask the Colonel.
They do call redheads "Blue".


I think I have one of those sockets, I always wondered what it was for.
I buy boxes of tools at fleas and garage sales and get some strange ones, look mostly for cheap broken Craftsmen so I can trade them in for new ones.
The local Sears Hardware clerks forget to take the tool back and throw it in the steel 50 gallon yellow drum-o-bustedness behind the counter so I periodically take the same broken one in. I've got at least ten 3/8" ratchets and a ton of Craftsmen chisels/screwdrivers.
I never have to change sockets, they all have their own dedicated ratchet.
