Have slow leak :

1- Got a new cap [ no it]

2- Tightened hose under reservoir [ not it ]

3- No coolant on cabin floor.

Did a search and found that some mystery coolant
loss cases can be a weak water pump seal.
Coolant slow leaks and evaporates to quick to fall to
the ground.

Also I read that the T-stat O ring or something like
that can leak over the water pump making it appear
that it's the pump.

My questions is : going to do oil changes soon.
Where can I look or feel with hand to see if this
is the leaks origin? I hear it's tough to see [water pump]
due to timing belt, etc.

**** One note : Some people in the search also said
a pressure test was of no help with
this type of leak.
