You can look at dipstick and check for moisture in oil , looking under oil filler cap for milky residue. Drain oil and send for analysis is another option.
So I’m not clear on your statement about dealer calling for pictures- they wanted your pictures or they sent you pictures? How did they...
Who at the dealership told you that- service writer guessing or did they perform some testing and then provide you with results pointing to HG?
You’re a captive audience to them and they’ll try and sell you an expensive job- so beware.
But you’ve already done a system pressure test as...
Can’t really tell from photos but if you think coolant is leaking down on tensioner from above - I suspect the underside of the thermostat housing area.
If it were water pump I think you’d first see it leaking from the weep hole and it looks dry in this picture.

But check your coolant 1st thing in the morning- under the cap as explained above.
Are you clear on how to check for coolant leaking under the crank pulley- to rule that out?
As others indicated- the radiator must be filled to the top of the neck where it’s trickling into the overflow. If it’s not it will keep drawing from the reservoir until it’s level. It may have never been burped/purged properly from your last TB service- and you’re now just noticing it. You...
I would not let them do a TB service just yet- and definitely no to Napa parts (strike one for your new shop). As remarked above any measureable coolant leaks under timing cover from water pump area would be wet under crankshaft (harmonic balancer pulley) at the weep hole.
is the radiator the...
Help us to Help you - if you start with providing a brief service history of anything relevant to the concern- such as- How long since the last coolant system flush? How old is the radiator? It’s it original or a replacement ? When last were heater Ts replaced, water pump replaced when? What...
