What the heck is this socket for?

[Jason280]

Picked this socket up at the pawn shop for $1, but can't figure out what it actually fits. I assume its some sort of axle/hub socket, but what exactly for? It has AmPro markings, but the model number is worn off.

Any guesses?

Appears to be the water pump tool for 4.6 and 4.0 Cadillac Northstar engines.

Link to see what a good deal you got, if you've got a Northstar in anything.

If you have a northstar, I pity you more than anything

You need a fancy tool for a water pump ? What was the engineer smoking when they designed such a thing ?

ever see where they put the starter?

Under the intake manifold

Could be worse, the engine could need case halves

Ever have to do heads on one? Go ahead and shell out the $500 for the block rethread kit. Coincidentally you'll need that water pump socket for the heads as well.

any kind of work on those are just nightmares.

I have something similar for my Bravo III outdrive.

yup.

So that sounds like the mercedes aluminum block that needed fancy $$$$$$ tools and inserts for the block. At least they kept the pump and startercin the right place.

An alternator on one is a real problem too. I had one, when it shate the engine I scrapped it.
