hi all, i recently had problems with my car overheating ( a vh with a vn 5lt engine) and since the old radiator had been leaking slowly i decided to put in a new one. after putting it in i looked up the capacity for the vn 5lt cooling system to know how much coolant was needed. the only prob was it took much less than it should have..

so my question is is the vn radiator larger than the vh? maybe this is why im having trouble with my car overheating.. any advise would be much appreciated
