hi i just finished winterizing my 2000 v/p 5.7 gsi after i drained the water from the manifold and block i put 2 gallons of anti freeze down the hoses to the manifold, block and the large hose to the water pump. i turned the engine on for about 30 seconds to mix it up. on my old omc when i did this i'd have anti freeze come out the outdrive. on the vovlo nothing came out the drive no water or anti freeze. is this normal? thanks, bob
