The reason I brought up the coolant is because of the different types out there.Cooling systems that call for ethylene glycol may not be able to use the newer coolants.I personally would stay with the Peak or its equivalent.

Picking the right antifreeze
Most antifreeze is made with a base chemical called ethylene glycol. Green dye is used in most brands, except Toyota, which uses red. Extended-life antifreezes, also with green dye, were on the market until two years ago. But the newest entry is a superlong-life antifreeze with a totally new rust/corrosion inhibitor developed originally for heavy-duty use (such as trucks). The original, from Texaco (used as original equipment by GM), is called Dex-Cool. The latest is Prestone Long Life 5/100. These two are orange.
The rust/corrosion inhibitors vary, but if antifreeze is green, assume that its life in a car with a lot of aluminum components is two years or 30,000 miles–whichever comes first. You can push that to a third year if the engine is all cast-iron. "Toyota Red" is a specific formula, but if you drain it, you can replace it with any name-brand American formula. Here again, the replacement interval is two years or 30,000 miles.
The inhibitors in orange antifreeze are not chemically compatible with what's in green or red. However, if you have at least 5000 miles on the green, the chemical bond with the aluminum components is "solid." So if you want to get extended life with a coolant installation, just do a thorough drain-by-dilution, at least three times. The coolant you drain out should be virtually clear, like the color of water. If it's still green, you have to repeat the process until it's all out.
With the radiator and reservoir drained, pour in the amount of antifreeze necessary–there should be plenty of room–and then top up with water. Follow the procedures we've discussed to ensure a full system.
