Its got the old type bottom hose fitting,a strange level float in the header tank,a hole in the front of header tank that looks like a sensor should screw in there,two small outlets on the header tank just above bottom hose,and a Gti6/Rallye rad cap will not fit it properly(neck of rad is too deep so cap does not compress on second stage of turn)
Cheers
