Hey guys! I'm checking (I tried the search but came up with nothing??) to see if this is a standard thing (it is obviously a diesel, and my boss has a 773 which is a diesel as well)- neither of us can see one on our machines??? Are they tucked in somewhere from the factory and are "hidden" if they haven't been used yet? Did you have to order it with it when new (both of ours have had previous owners)? If they didn't come with one, and if they did they should be VERY EASY to see- what do you guys recommend putting on; and where do you recommend putting them (ie, it one of the freeze plugs facing you when you open the door, or??)?? Thanks for some guidance to a newby!!! Also, while on the topic, what are most using for antifreeze? Do you have to use what is factory, or can a person use the ethynol (sp??) type? Will it hurt to use regular green AF if the other is flushed out?? Thanks again!!!
