Yesterday I discovered that my coolant was leaking. The temperature gauge started to go up so I stopped and had a look. The leak is coming from the pipe that comes out of the front of the engine between the alternator and the flywheel. The pipe is connected to a rubber hose that runs into the firewall and inside the truck. There are 2 hoses running side by side into the firewall. Can someone tell me what this pipe is called so I can try and order one as soon as possible and get a new one replaced.

 

I believe you are talking about the water pump. You did not say which engine you have.

 

........2 hoses running side by side into the firewall......

Sounds like heater hoses to me!
