looks like your heater core is leaking.

 

do u know to take that black box off?

 

i am think you have to take the whole dash out.

1. Disconnect battery ground cable.
2. Disconnect heater hoses on engine side and plug heater outlets.
3. Remove right side cowl trim if so equipped.
4. Remove glove box, then structural brace through glove box opening.
5. Remove right half of instrument panel lower reinforcement, making sure to disconnect ground strap.
6. Disconnect control cables, then blower motor wires on engine side.
7. Disconnect wires from resistor block.
8. Remove screw holding heater to cowl side sheet metal.
9. Remove 6 heater retaining nuts on firewall, then remove heater.
10. Remove mode door crank and 15 screws to remove cover from housing, then slide heater core out.

thanks , i was hoping i didnt have to take out the dash, dammint
where did ui get the pic form what book?

 

i got the pic from alldata.

 

I also am going to have to replace my heater core so I sympathize with you. I am getting a fogged up front window when I turn on the defrosters and that fragrant aroma of antifreeze. The leak is still small enough not to be dumping fluid inside the truck. Good luck.

 

I had a leak also but it was the hose

 

can u share some more?

 

what more do you want?
