Hey guys,

My coolant level is below the "low" mark on the overflow tank, so I figured I'll pick up a gallon and top it off. After doing some searching around the forum, I found a few conflicting part numbers, so I just wanted to know if anyone can confirm my assumptions or correct me if I'm wrong. It seems like both of these coolant types are the same, but the toyota stuff is ~$10 more.

Here's the conclusion I came to:
Toyota p/n: 00272-GTBC1
Subaru p/n: SOA868V9270

So, are these the correct coolant part numbers for our cars?

Thank you!

Coolant expands as it warms up and contracts as it cools, so you need to specify when each measurement was taken. Also, make sure the car is level. If you actually are loosing coolant that is not normal or a good thing. There is another thread asking essentially the same question, you may try to search for that. If you are truly loosing coolant there are only three possibilities. Its dripping/leaking due to a loose hose or connection (not to bad), its boiling-over and literally overflowing from the reservoir (not good, could be worse), or it is getting into the combustion chamber and being expelled in the exhaust (very bad).
