okay so when i got my truck i noticed that it was running kind of hot. (my temp gauge only says C & H and it was between half and hot) and so i get out and figure out theres a low level of coolant in the radiator. stick some in and the truck runs a lot cooler. once i park it, the coolant starts dripping out really fast almost pouring out from who knows where i think its a radiator hose or something but it leaks fast and i can go through a whole can of peak 50/50 coolant in two days. i put that alumaseal stop leak in there and it didnt work... now my radiator has a really low level of coolant and none in the overflow tank. what should i do? how do i replace the radiator hose if that's the problem? can i just dump water in there for now as a temp fix? on the can of 50/50 it says do NOT add water but there's gotta be a better way than blowing 7 bucks for coolant each time i want to go for a drive.
