The heater core is inside the cab under the dash on passenger side. The 2 hoses on the outside you disconnect over by the old fan housing. Only thing I can think of is when you crank the truck up it sloshes the left over coolant out of the heater core and it runs down into the cab. Get a shop vac and suck it out are better yet take the inside housing out of the truck also since it's not going to ever work again.
