Are the fans in series in our LT1 engines? Can I remove one of them and still have one working fan? I'm in the middle of doing a few things on the car and the engine isn't running so I'm hoping someone knows before I reinstall everything.

QUOTE (Jon A @ May 31 2004, 02:56 AM) On your '94 you have one fan that kicks on first and a second that kicks on after that. In '95 or '96 they switched to a dual speed set-up where both fans kick on at the same time at low speed and then they both kick up to high speed when required. Not 100% correct. (Wow, I'm correcting Jon) This is all taken from my Helm manual and personal experience with my '94. Early '94's are the way you described-one fan at a time. Later '94's run both fans at two different speeds. The older models run one fan at 12 volts and then turned on the other at 12 volts for high speed operation. The newer ones run the fans in series at low-speed and in parallel at high-speed. IOW, at low speed they each see 6 volts and 12 volts at high speed. My '94 was built in 12/93 and has the newer system. I found this out when wiring my cooling fan switch. I believe the only difference is the wiring (series vs parallel), but I'd have to check my Helm manual to be sure. It's been a while since I wired up my fan switch. |
