Having problems with your 2003 Toyota Corolla ?
My mechanic told me the drive belt tensioner is leaking. What does that mean?
The engine coolent is ofter routed through the belt tensioner by cheap plastic fittings that leak.
I think that model may use a hydraulic type tensioner, if its leaking, its bad.
