Do you have any coolant in your system?

Have you confirmed that these new fans are actually coming on? With the A/C on you will have the secondary fan running and as the engine temp reaches between 202 and 212 degrees, the CTS= coolant temp sensor will activate the primary fan through the ECM= electrinic control module. A scanner will confirm that a request for activation is taking place. Sounds like you need a qualified technician to walk you through the diagnosis of your vehicle.
