coolant problems
 

I recently posted about some problems with my Rx-7 one of wich was a leak in the coolant. Well originally I filled the radiator with this liquid alluminum stuff that was soposed to seal any hole that were leaking but I dont know if it worked or if there is a different problem as to why it is leaking. I looked under and its dripping in the passenger side area but I dont know what it is.
I was going to just get a new cooling system for it but I want to know if anyone here knows what els I could do.

Theres a number of hoses on the passenger side. Most notable is the heater hose. It runs from the firewall to a hardline, and then closer to the radiator theres another 10 inches of rubber line. This hose is about 1 inch in external diameter and is prone to leaks due to manifold heat. THere are also some small hoses which run throughout the throttle bodies, and if you have a turbo, the cooling line comming out the bottom is a small short rubber piece about 3/4 inch in diameter.
