hey, quick question...My truck is starting to smell a bit like coolant inside, usually after the engine has warmed up. Not a real strong smell but it is there. Also my windows take quite a while to defrost. I'm thinking its the heater core. Any other ideas what it is. And also, does anyone know where i can get a guide on how to either check the condition of the heater core or how to replace it. Thanks alot!

Take a look up top at Steve00ram360's Merry Christmas thread and you can download the repair manual. That should help you out quite a bit.
