Hi,

This is my first post here. I own a 2003 Toyota Echo US version with automatic transmission, which is equipped with a standard factory transaxle oil cooler. The cooler resides right below the radiator and connects to the transaxle via a pair of hoses.

The cooler is shown on page CO-14 of 2003 Toyota Echo repair manual. The manual does not show the flow direction of fluid. I wonder if anyone can help me to identify which one of the two hoses (driver or passenger side) that carries the fluid out of the cooler.

Thanks,

Simon

No answer to this since '04. I would also like to know this for I have a flush coming on my 2003 Echo. Wondering if it is the same one on a Corolla? I've done a few flushes on these.

Generally, the outflow(going into the cooler) would be the upper hose and the intake(coming out of the cooler) would be the lower hose, that way, there is never an issue of fluid not getting back into the transmission if the level was low.

Looking at the diagram, the passenger side is the outward flow from the transmission, and the drivers side is the inward flow back into the transmission.

CORRECTION

I actually just finished this flush and the correct hoses are the PASSENGER side hose is coming from the cooler back to the transmission.

The DRIVERS side hose is going to the cooler from the transmission.
