Hello from Spain. After a few years with the car stopped, I am fixing it. The car loses a bit of coolant from the connector in the photo. It looks as if the thread has cracked, or maybe it's scale. Can you send me a photo of yours to see how it should be? I'm afraid it will break. If the thread of the engine block is broken, can it be fixed? thanks

 

That is threaded into the manifold - not the engine block - and of course it can be fixed. May require removal of the intake to properly accomplish it. Doesn't look like it's repairable any other way. Take it apart and replace what's broken/cracked/leaking, etc. You may have to modify it as you are in Spain and that part is probably discontinued even here in the US.

OKAY.
Do you know if there is any tutorial about how to remove the manifold? What else is convenient to change? Gaskets for example? I have looked through the pages that I know the part, but as you said I cannot find it. Does anyone know where they can buy it or the reference of the part?
Thank you

 

If it is still the stock part, it is pot metal (junk). GM used to sell a repair kit for these. Included the fitting, clip and some seals. I looked on RockAuto and didn't see the repair kit. Dorman's Help rack also sold the kit. Note that the repair kit used a machined steel part, not the pot metal.

Due to your location there may be a better way to go. It uses standard AN fittings and hose to replace the GM junk parts. I'll look for a thread on this.

OK, found the thread. Here is a link to the mentioned post:

A review of the whole thread is recommended.

Note that doing a few of these that the pot metal part breaks off and leaves the threaded section in the manifold. I've been able to get that part out of the manifold using an easy-out. But do need to be careful and go slowly. Don't want to crack the lower intake.

Hi.
The drawing that I have put above, is it correct? Does piece number 1 exist? Or does piece number 2 go straight to the manifold?
It's this piece ?

 

That is the repair kit, good find. The threaded part on the fitting is what screws into the intake manifold. Then the plastic clip and o-ring is used to retain/seal the water pipe. From your diagram it looks like piece 1 is the one that needs to be replaced.

Part 2 being the water pipe.

The spare part has already arrived and I have disassembled the broken part. It's a tough job if you don't have long arms and little fingers. I have not wanted to remove the clamps from the tubes because surely they are stuck or later it will be difficult to mount again. The connector has a shattered thread and is stuck inside the manifold. Do I take it out with salfuman ( clorhidric acid ) or some chemical product and scratching? Will chunks go into the manifold? There is no place to work. To remove the throttle body with the heather pipe, the pipe has a screw behind the alternator, but I can't get to the screw ( number 14 at the photo ). Must I remove the alternator?

 

solved. I have been able to remove the screw with patience. And the corrosion is not hard, so I can remove it little by little

 

I think there is too much separation, the threads of the thread are visible. It 's right?it goes very hard and I'm afraid of breaking it. Doesn't lose water

 

That is OK, the threads are tapered which is why it keeps getting more difficult to thread in. Too tight and the intake manifold can crack.
