Whats the CFM of the current belt driven fan?valenburg wrote:I was thinking about this the other day when looking under the hood of the Pathfinder. Do you guys think removing the belt driven fan and mounting up like a 12+inch electric (2200cfm) fan as a replacement would yield any type of gains or even any negative effects? My grandma had an 85 crown vic and that was a mod that some did on it and my 81 toyota corolla as well. It might help to run a bit cooler too since at idle the fan would still be at a good speed. Just a thought.
You are correct, however I've never seen the electric kick in on my 05. I've heard it sounds like a jet taking off when they do though...08Datsun wrote:I'm not sure about the older models, but my '08 has a mechanical and an electric fan. The electric one is a two speed and seems to do most of the work. The mechanical fan has only engaged a couple of times, and that was 1 mph crawling in low range 1st gear in maybe 90 degree heat. It never has engaged otherwise, even in 120 degree heat or pulling our tent trailer. It will likely never engage for you up in Maine.
The fan of choice for electric fan swaps is a two speed fan used on the 3.8L Taurus. High speed is 4,000 cfm and I'm told it takes a 70 amp relay for the high speed.
