2009 Wolfsburg Jetta Cooling Fans dont turn on
 

I bought a 2009 wolfsburg jetta, replaced the radiator, intercooler, condenser, fans. and i hooked everything back on and the car keeps over heating! I cant find the valve to get all the air out of the cooling system. and the fans will never turn on! please help me getting really worried as i have put in a lot of money into it already.
