needed a drop of coolant added since it was new! I added some coolant and
could see no visible leaks underneath tonight. Will check again in the AM.
If I see leaks...........it looks like it goes in the shop tomorrow AM.

On many vehicles the coolant tank also acts as an expansion reservoir that
accepts coolant that is pushed out of the radiator when it is heated up.
Coolant may also be sucked back into the radiator when the engine cools.
It is possible that your radiator may only be half full....after you fill
the reservoir, so a heat cycle may pull coolant from the reservoir and make
it look like you still have a problem. A few heat cycles, and keeping the
reservoir topped off, will let you know if you still have a leak somewhere.
Not seeing any coolant leaking or driping from the engine is good, but if
you have a head gasket leak or cracked head/block the coolant could be going
out the tailpipe. Maybe if there is a coolant leak into a cylinder, that
sparkplug will look different.
