If what's in there is anything other than the color red, you need to flush the coolant system to avoid mixing different types of coolant, which will gunk up and cause corrosion inside the cooling loop.
Hey, thanks for the reply. I don't know what's in there currently. Just looking at what I need to get to top off. Thank you.
Assuming that there's some kind of colored coolant in there now; because you don't really know what kind of coolant it is, the safest route (until you can do a complete drain/refill) would be to just top off with distilled water. The total capacity of the cooling system is 11.6 quarts; even if you're topping off with more than a few quarts of distilled water, the risk of freezing is negligible. Especially now that that were into summer. The distilled water will eventually mix with the existing coolant.
Once topped up, check the coolant level for the next few weeks to make sure the level stabilizes and doesn't fall. You shouldn't be losing coolant.
You really can't go by the color of the existing coolant to determine what type of coolant is in the system. Simply because most aftermarket coolants are designed to mix with whatever color the existing coolant is. There is no standard for coolant coloring. Coolant chemistry is more important.
The attachments should be helpful when drain/refill becomes necessary.
Anyone have experience with Aisin ACT002 50/50 prediluted coolant? I noticed it at Rock Auto the other day and was curious as it was quite a bit less expensive than the Toyota branded coolant and it was Aisin branded.
