Cooling

[Rampant_ant]

Has anybody out there thought or heard or installing cooling fans on the FJ?

Its been on my mind but I don't know if it would be worth it

I believe it has been thought about and dismissed, a fan big enough to be effective would be too big to mount.  It's spoken about from time to time but I've never seen it done.  It's a great idea until you apply some serious though to it.

A bigger oil cooler would be a better alternative IMO. I've seen some threads here on the subject.

A fan for the oil cooler itself would be a good idea if you have to deal with a lot of traffic and if you have increased compression. Setrab makes fan packs.

See thats what I was thinkin. Bigger cooler and maybe a fan but I don't know.

Its a regular occurance on my commute that people decide to drive into each other because they suddenly forget how to drive

 The cooler is really only effective when air is flowing through it. Stop and go traffic gets the engine hot...real hot with extra compression. Even with a large cooler.

An oil cooler fan on the FJ in Aussie heat would be pointless, especially in traffic where the ground temp can be up as high as the air temp (35-40 deg C) plus all the exhaust and engine heat - it would simply be blowing hot air on hot oil and not much heat transference would occur if you were standing still) just a drain on the battery

Thats somewhat valid but moving air at 35° is stilll better than the stationary air in the cooling fins at engine temp.
It's not as effective as cold air but any difference in temperature has a cooling effect.

The principle is effective on liquid cooled bikes with a radiator and fan and they operate under the same conditions (in regards to exhaust and engine heat). Obviously liquid cooling is more efficient but the same principle is involved. The fact that the oil is hotter than the surrounding air (and it better be or you wouldn't live to talk about) it will lose BTU's to the fan driven moving air. When it is that hot and you know you will encounter stop and go traffic use a liquid cooled bike if it is possible.

Sure I understand that, but where would you put the fan? and how big would it need to be to make a worthwhile or even a noticeable difference?

and JMR: do you have a spare liquid cooled bike on hand?
I wish I had the $ for another more fun commuter, the time to ride both bikes more often, and somewhere to store said bikes!

Check out the fan packs Setrab makes....they are pull units that are about 5" thick. I'm sure they can be made to fit. I haven't done any testing so I cannot say what temp drop etc would occur but a well designed fan can pull pretty good CFM.
I use my busa a majority of the time now. My FJ enjoys a well deserved pampered life now.

You have a link for that Jeff?

[Brook]

....... sorry for the delay, No Sir, no link.
but, what Tengu said, is 100% correct. [with the fan in that location, anyway] all it is doing is blowing a lot of hot air on top of the motor ........ at red lights with the fan turned on, the oil temp.gauge, shows it.

That's why I removed it and installed two small computer fans in front of the... Earl's 10row oil cooler.

I put the fans in front on the cooler, just for that reason. I did not want the same results [the fans blowing hot air]. > all trial and error<
