    So, I have heard or read somewhere that in order to add antifreeze to the coolant system you have to go to the dealership. Now I could understand this if you replacing a large portion of the coolant and had to put the system in a vacuum. But is this trus if you are just adding some to top it off.?

    I think what coldheartid meant was if the cooling system is pressurized and to add coolant that the dealer had to do it. If you drain the whole system you need a vacuum system to get the air out of the system so you don't get a vapor lock and over heat. To just add coolant , don't open rad cap when car is hot just like any other vehicle, let it cool down and you will be ok. I took my rad cap off and checked the spring pressure on the cap and nothing happened. System is not under constant pressure.
