Internet explorer is not allowing the downloads of the manuals. Can you send them in a PDF or something that I can print?

Does it take a special tool to diengage the hoses from the heater core and can I reach them from the cab to disengage them after I remove the engine cover?

I want to change the anti freeze anyway so would draining the radiator negate the need for the plugs? I'm just wondering on this but is the blowere behind the core, that is when I remove the core will I be able to see the blower or is the blower going to interfer in the removal?

Special tools are recommended, but you can remove the hoses by reaching in and squeezing the 2 tabs at the end of the fittings to release them you will hear them click when they release. After they release just pull the hose. From the inside if you can get to the tubes you can just cut them off with a hack saw since the core is already leaking then pull the hoses out with the tubes for acess to release the tabs. The blower should not interfere, Al
