You can avoid getting stranded by identifying signs of extreme wear before they break. In 2003 GX470s with the 4.7 liter engine, coolant leaks are most likely to occur where the hoses connect to the engine, but it can also leak from the reservoir or from the hoses. Look for cracks in the hoses and analyze the brittleness or squishiness of the hoses in your GX470 - if the hoses are hard to squeeze or squeeze very easily, it's time to replace them. The video above shows you where coolant hoses on your 2003 GX470 Base are located and the steps needed to analyze them.
