Back flushing

WARNING: This page is about a different car, the 2005 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

Following the power flushing equipment manufacturer's instructions, connect the equipment so the flushing fluid flows in the opposite direction of normal fluid flow.
Flush oil cooler/lines until discharge fluid is clean.
CAUTION:
- If the cooler can not be properly flushed using recommended equipment, send the radiator out for subcontractor cleaning or replace.
