Coolant Smell on 2002 Grand Cherokee – No heater core symptoms

This one is a mind boggler……

Got this Jeep in 2008 with a bad heater core. Bought the heater treater kit, new core, and new evap….figure I’d replace all in one shot while in there. This was done December 2008.

Core went bad again after 7 or 8 months and was replaced free in September 2009. The coolant smell stuck around though. Heat works great, defrost does too with no residue on the window. When I step out of the Jeep after a drive, I smell the coolant more around the front/engine area.

Coolant level is fine, no smoke or smells from exhaust, oil is clean, so I’ve ruled out head gasket, and there are no leaks in the driveway, garage, or parking spot at work.

Could there be some microscopic leak at one of the hoses or radiator? And then the heater sucks the smell from the engine bay into the vehicle?

It just doesn’t add up what could be causing the smell…..

Anyone?

Thanks!

How about a pinhole leak in the system such as this?

Don't think this is my issue.....no missing coolant, not one drop. I do smell the coolant in that general area.....so maybe we're onto something?

What are typical signs of a failing water pump (if any?)?
