I don't know why they don't put a warning light along with the temp
gauge but they don't. Who constantly monitors the temp gauge? Anyway
you did one of the things you shouldn't never ever ever ever ought let
happen to an engine with an aluminum head, mainly overheat. The steel
sealing ring on the head gasket is apt to embed into the aluminum and
indent it but it may hold, probably should and will hold if it didn't
get to hot but it's not a good thing to have happened, and it also
messes with the effective torque of the head bolts by pushing the limits
and having to then hold when the engine is started cold. I'd take it
easy when the engine is cold and let it warm up before gunning it to get
on the express way.
Find the source of the anti-freeze loss and keep an eye on the
reservoir. A radiator cap not sealing and holding proper pressure will
lead to loss of coolant over time.
So what to do now? I'd make sure the sealed part of the system is
topped off the radiator cap is sealing properly and drive it and keep an
eye on the reservoir and don't let it run dry. Keep looking for leaks
it's a good habit to look under the car before getting in it and when
you back out (every time) to see what new stuff has dripped from it,
engine oil, transmission fluid, power steering fluid, antifreeze, AC
condensate what ever it might be. Hopefully it's just an easy to fix
leak and you will get many more miles down the road.
