Up in them guts - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I've got pretty much everything between my engine and radiator dismantled (belts, fans, working on pullies) and have a couple questions.

I'm replacing the clutch fan and a busted a/c fan with an electric. Anybody have any recommendations on wiring it up? I have a method I'm going to try, wiring a switch to the a/c fan relay and running it off of there untill I can afford a thermostatic sensor. Wondering what some of you who have completed this have done.. .

Anything else I should do aside from replacing the belts while I'm all up in them guts? I wish I could afford an ASP underdrive pulley right now, that factory one is heavy as hell <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt='

'>

Oh and any tricks on getting the pullies out? I searched 240sx.org, found directions indicating I need to pull off the bigass bolt on the end, though that's just cranking over the engine. I don't have a pnuematic wrench, just a breaker bar, ratchets, and torque wrench.

er, project is a bit scrapped <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt='

'> The fan I bought didn't fit with the stock intake so I'm going back to the clutch fan. How I was going to wire it was run a switch to the a/c relay. In theory, I would hit the switch in the car to turn on the fan, and not need to run 12 guage wire all the way back to the fan. Not gonna happen yet, though. The only fan I can find that will fit is only 12", which I don't trust in the heat. Car's mostly put back together, been a great learning experience :-) Shout (the laundry stain remover) is great at degreasing parts when you have nothing handy. A slow oil leak going on for damn near a year, made one helluva mess down there. I'm suprised it didn't fry my alternator given how caked in crap the front side of it was. Glad I got in for a close look, and got the problem fixed and cleaned up :-)

Not sure about the S13, but on my 97' the A/C fan comes on if the coolant temp gets too high with the a/c OFF. I guess to help out the clutch fan... I was planning on just removing that little a/c fan and using the 12v source and relays from that circut to power my new fans. Makes sense to me..... <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/thumbs-up.gif" border="0" valign="absmiddle" alt=':thumbsup:'>
