How Bad is this Coolant Leak?
So... topped this off for the first time in April after a warning... now two months later, another warning and lost half an inch.
should I panic and only drive this to get headbolts replaced or could this be anything?
i have just under 100k miles.

If you breached the HG, the heads need to come off.
Check for evidence of coolant in your undertrays before you toss it on the flatbed.
If it is in fact just a leak, consider yourself lucky. The bolts can be done one at a time in that case

Update: they found now internal leak so assumed to be being burned off in the exhaust.
My Indy shop will be replacing all the gaskets and headbolts.

same same. After our years there’s an updated pn. Since headbolts require removal of the “buckets” people doing bolts almost always seem to update the buckets to the more wear resistant version. Take a look at RM European. They had them on sale not too long ago.

So... bolts not broken but two were stretched and corroded.... replaced head bolts, gaskets, spark plugs, etc but coolant also got to and damaged water pump so replaced that too.
