rent or find a buddy that has a coolant system pressure tester and use it. you will chase youre taill trying to find a coolant leak without one unless its obvious. a coolant system pressure tester will give you an answer in a matter of minutes.

x2 about that

add the dye to the coolant , then drive the vehicle to allow the dye to circulate all through the coolant.

you will need a pruple ultraviolet light to show where the coolant is leaking from
