Hello everyone - I just got back from a short drive in my 03 Corolla that has only 21K miles, and
I'm changing the oil and discover some dried pink caked looking stuff on the inside of the serpentine belt,
on the back inside rims of the drive pulleys and on the passenger side of the radiator.

Anyone have this problem before and know what it is?

Is it leaking coolant? If so, from what?

Thank you for your help.

Never mind - I figured out it's coolant leaking from the water pump and the pumps are crap on this vehicle. Water pump leaking at 21.9K miles.
Pretty much sucks.

Yup, coolant leaking from the weep hole on the waterpump. Similar pumps to the ones that they put on the 8th gen Corolla - but on the 9th gen - they switched to a longer life coolant. Not sure if that had anything to do with it. Sort of hit or miss with the 9th gen - either they go bad early (under 30K miles) or go 200K+ miles with no problem.
