Press. it up hot.
Lost down from 21LBS to around 15LBS, When I noticed Some coolant leaking from around the waterpump area.
Either the bypass, (wich I did not change) Thermastat gasket, or weep hole.
Anyway Im going to tear it down this weekend and find where its comming from.
I think I will change the WP even if its not leaking, since im down there.[&:]

Glad I dont have to change the heatercore
