Hi there i changed the engine on my 112cdi Vito and just need help with one problem ??

engine runs fine heaters work fan cuts in when should BUT.

the coolant pipes seem to be rock solid and just want to know if this is normal there is no loss of coolant. if i put overflow pipe in a bottle of water it does vent air (shown by bubbles) but only air no coolant. Normal or Not ??
