thanks man damn lt1s are wierd to me and do you have any idea or a solution for the fan issue thats kinda the main thing we need to take care of i mean we really dont want to switch to a manual switch so whatever help is appreciated thanks
Could be tuned to come on like that. If there is a "check engine" light on, that will cause the fans to come on immediately.

I've ready many things while going through the process of rebuilding my Z28. I've read that from the factory, the fans are programmed to kick on at an insane temperature reading, which I can confirm that is true. Before my Z lost half a compression ring, I was irritated when going out for lunch break trying to get something through a drivethru quickly, and every time I had to shut off the car while waiting in line so I wouldn't chance it overheating.
My suggestion if burping the coolant system don't help much:
Get a 160* thermostat, get your computer tuned for the fans to kick on at a much lower temp (pcmforless.com is where i went)
good luck

Chavez is correct, if the check engine light is on, the cooling fans will come on by default. If the light is on, scan for codes and post them here.
