thanks again

Toyota uses a red coolant that you can get from the dealership. It cools better and generally provides superior dielectric insulation. It is more expensive, but you only need a gallon... so it's no biggie. If the coolant system had any other type of coolant in it previously you MUST thoroughly flush the coolant system before returning to the red coolant. Some types of coolants are incompatible and will emulsify (thicken) when mixed.... don't want to add any more sludge to the system.
