2009 Ford Taurus coolant disappears but no outside leak
White smoke appeared on the right side of the engine, but no visible outside leaks.
Refilled with coolant but lost half of it within 1 hour. Engine temperature indicator was
normal but engine sign "service engine soon" came on. Could this be gasket or heater
coil issue? Could this be a faulty thermostat or water-pump problem? Thanks
Sounds like a bad head gasket or cracked head. Take it to a shop and have it pressure tested.
there is also a combustion leak test kit you can do yourself, its around 45 bucks and is pretty easy, lots of you tube vids on how to do it too.
Sounds like a blown head gasket !!
