or if you want NOS
www.nos4gn.com

it could also be the fan switch on the intake, the fan itself or the harness/connector.

If the fans are coming on late it sounds like the intake switch (hi speed fan) is working and the low speed is not.

Are you sure the fan signal from the ecm is working?

If only the high is coming on it shouldn't be overheating.

have ya pulled relays and checkd connections for corrosion, is integrity of cooling system sound. is the pcm commanding fans on for a reason?
if above all checks out have you checked into control ckt of relay. aka coil side of armature.
