Hole in my Exhaust? Losing Coolant?

[Peloton]

Hey guys, I suspect there is a hole in my exhaust just after the engine block, possibly underneath the passenger side area,
I am also losing coolant somehow (possible gasket leak?), and can smell exhaust fumes from the engine bay
(I suspect it is actually a hole in the exhaust which I cant see directly but I see small amounts of exhaust smoke coming out of faintly.)

• My Yaris is a 2007 Sedan Model
• 170 000 Km, Automatic
• Live around Hamilton, Ontario and drive quite a bit on the QEW
• Harsh winters with alot of salts (I believe this is where the it has rusted a hole in my exhaust)

If anyone knows about exhaust problems with the yaris, any help will be appreciated.

The coolant leak issue is somewhat a mystery to me, I've had the water pump, and alternator replaced,
alternator being the latter. Could this issue stem from those two replacements? Or do you think it could be a gasket issue?
