Intake manifold?
okay so over the last few days its been gettin cold, ive noticed a few things about my new truck..
when i first bought the truck i noticed the ac and heat go to the defrosters when on the gas. so i googled it and thought it was gunna be a quick vaccum leak. all the hoses behind the battery look brand new. no leaks i can feel or anything.
im loosing antifreeze, its dripping down around the starter and off the bell housing. i can smell antifreeze sometimes in the truck, almost always when i shut it off and get out.
Last, my heater doesnt blow near hot enough, after driving for a while, it does get comfy in the truck, but the air actually comin out of the vents is warm at best.
could all of this be caused by an intake manifold leak? it seems plausable to me. also i have tired to tackle each of these problems seperatly, with no luck fixing any of them. any help would be greatly appriciated guys!!!!

Second the antifreeze leak. Most commonly will be the plastic quick connects that connect the heater hoses to the heater core. Could also be a bad heater hose so check all that.
Third is the warm heater air. Probably broke blend door or a bad blend door actuator. Need to cut an access hole in the plenum behind the glove box to check blend door operation.
