Still losing coolant after pressure test! Help!

My car is losing coolant for some reason.... The last time I did a coolant flush was two months ago, and today when I checked the coolant, it is already below the MIN level (no warning yet). What's really weird was that I did a pressure test before the coolant flush and it showed no signs of leaks as the pressure did not drop over a 5 minute period.... Please help!

Most likely your coolant reservoir is cracked. Mind did last year and it's common.

That's weird cause I see no signs of dried coolant near the reservoir though...

Did you bleed the system after the coolant flush? From max to min in 2 months is not bad after a flush.

I'd just top it off and check again in a month. Possibly some air that was still in the system. Really only 3 places it can leak, cracked expansion tank, into oil in the OFH, at the radiator connection.

Okay, I will keep an eye on the coolant level. Thanks!
