Does anyone kow of any good product to stop a radiator leak? I can' see where the leak is exactly. And also may I have this leak because I bypassed the heater core hoses because it got messed up? And also have no thermostat.

Theres no "easy fix" for a radiator leak, most of the time the leaks develop in the seals between the plastic tanks and the aluminum core, the only FIX is a replacement radiator.
Most products that "seal" leaks work for a short time and could clogh the radiator passages.
Dont even try it, get a new rad.

Anything you put in your radiator to stop a leak, just isn't worth the hassle it will cause with all your other components!!!!
Believe me I speak from expierence!!!
Some mechanic junked mine up, and nothing has been the same since...
still contemplating changing out my whole coolant system!!

The best product I've seen for a leaking radiator for a mustang is a nice shiny new fluidyne. :thumbsup
