I have a problem with my Ford Mustang 2000 V8 4.6 L

I've already replaced both gaskets. I think the problem might be in the water circuit because the water pump's impellers are on the right side, and the accessory belt drives the pump pulley on the left. It works like that. This link shows the pump it uses: articulo.mercadolibre.com.ve/MLV-4158271...or-ford-original-_JM . I downloaded the workshop manual for a 2000 Mustang. The last thing that happened to me was that it overheated and the water mixed with the oil.

The normal thing is that the water from the radiator in the upper part goes, remove the sleeve and try to see where the water goes with the engine ripped. Greetings!!
