Why not take the propeller idea all the way and extend a shaft through the radiator and put some kind of prop on the end? If you even add some kind of duct, you'd get a kind of 'ram-air' huh?

how easy would it be to put a round hole in the (middle) of the radiator core?

BTW, thanks for all the info. I'll have to try it all out if/when I get my car back. I have a long list of stuff to do...

thx

A good radiator shop could modify the radiator, but you would probably need some sort of bearing to support the longer propeler shaft. Also might want to put some universal joints on it to keep it lower so it wouldn't hit the hood.

When you take the fan off, do you have to first remove the fan shroud? there doesn't seem to be much room to work inside the shroud. I assume using some spanners, you can get those long bolts out?

thx

Well if you can do it without removing the shroud your pretty good I'd say .

once u get rid of that just a 10mm spanner i think from memory or was it 8mm :cheeky: .

You'll have to remove the fan shroud first. Drain the coolant and reomove the upper and lower radiator hoses. Remove the splash pan from underneath. Remove the three screws that hold the two halves of the fan shroud together. Remove the lower half from underneath. Remove the screws that hold the upper half and remove it. I use a deep 10mm socket on a 1/4" drive ratchet to remove the four bolts from the fan. Remove the four nuts from the fan clutch. When re assembling, if you put the retaining clips that hold the screws on the bottom half of the fan shroud, you can screw the two halves together from the top and next time you wont have to get underneath the car or drain the coolant to remove the fan and clutch.

Good thing you replied i didn't realise it was so much work to remove the shroud none of my Z's have had one unless you count the thermo fan 260z i owned.

I think they didn't come on the early 240z's but i might be wrong.

It sounds like it's not too hard. But it'll take me a few hours to do.

thx.

My associates at work know me for being very thorough in my research. I have all the info I need, thx. I think we're thoroughly discussted about this subject?
