In this case, the color of the coolant has everything to do with it. Unlike green coolant, Toyota's pink coolant is a non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology (a combination of low phosphates and organic acids).
From the manual: "Use of improper coolants may damage your engine cooling system. Only use Toyota Super Long Life Coolant or similar high-quality ethylene glycol based non-silicate, non-amine, non-nitrite....coolant....[etc]."
In 2003, that '95 Tercel didn't even have 30,000 miles on it when Jiffy Lube worked their magic on its cooling system.
