Fans setup to be pushers, flip them around and you'll have much better luck. Hard to push air through objects, it works much better creating low pressure behind the object and drawing it through.

If you need a physical example try pushing a rope. You will spend an eternity trying and get anywhere besides creating a big pile on the ground. If you pull it, very easy to get it where and how you want it to go.

That's a nice radiator. You should have no problems with cooling a FG33. Looks like its a front to back double pass. I would change the fans to be pullers like 914forme said.

Yes, you could use the AC wire as a switched source to power the fans manually if you wanted to.

On the EZ30 you can also use it to bump up the rpm if you have low idle issues. The ground wire for the power steering pump will bump up your rpm as well.

Thanks,..Iam hoping to flip my fans over this weekend,get my engine in place and start to wire it up,..plus ,get my rad system completed, I will mount the pressure can and the overflow bottle in the front trunk area,only problem is my bleeder valve is on the bottom of this radiator so not sure if I can burb it as I need to with that design. ??

To burp it right you need to add a bleeder at a high point.

(IMG:style_emoticons/default/agree.gif) Or break a hose clamp loose to bleed which is messy and dangerous to your pets health so don't leave it pooled on the ground. You could get a head start on it by pre-filling the radiator. BTW, I measured those fans and they're too wide; each 13"W. (IMG:style_emoticons/default/beerchug.gif)

vacuum bleed the system is the only way to get it the first time. Used to do this with all the ricer crap that came through the shop. Even with the bleeders the Civics where horrendous for not getting all the air out. Started to vacuum bleed the systems, and problem went away.

They are pretty cheap and worth it in the long run

[flmont]

Thanks 76-914,.appreciate the effort.

914forme, I found a inline radiator splice that has a presure cap on it was going to try and fill the system from the outlet side,run engine and burb with the presure cap,.Ill try and capture a picture of it dodges use them but they are made of plastic...

I'd use this as it has space to catch air...

Pretty much the radiator bleeding setup of my first water cooled 914.

Or install a brake bleeder valve so you can use a wrench instead of your hand to bleed off the air from the hot coolant...

[flmont]

Ahh thats a good Idea Thanks

[76-914]

I've got Schroeder valve in mine. (IMG:style_emoticons/default/beerchug.gif)

[BIGKAT_83]

Looks to me like the radiator already has a bung in the top left corner. You might be able to add a Schroeder valve there.

[914forme]

You can also use a VW Deathstar and make the system self bleeding.



The larger connector goes to the inlet side of hte pump using a Tee fitting. The top taps from the pressure side of the engine with a smaller Tee. Put it high, and it will create a self bleeding system, pretty simple. And it has a fitting for coolant level monitoring so, you wire it up and you'll know when you need to add more coolant to make up for the air you sucked out of the system.

You can do the same idea in Aluminum and other materials also.

914forme,..is that the VW beetle tank..??

and BigKat yes good catch didnt even look at that ,but yes I can now switch those 2 around and have a bleeder on top...Thanks Frank

Beatle, Jeta, Golf, EOS, maybe even crossed into the Audi lines. The Deathstars where used for lots of years over many many models. Can be sourced cheaply from pick and pulls. If overheated though they are junk, replace them. You can tell if no longer a sphere find another one.

[flmont]

I would think the out bound line is the highest point to fill the system right,I intend to do it this way ???

[flmont]

914forme,..is there a bracket that goes with that ???

[914forme]

Yes Pick and pull is your best bet. Some have the mount flange in plastic just bolts to the car. Some have a metal cage to Keep it in place. Majority of 1990s to 2010 VWs have them.

If using the VW death start or similar coolant tank, you make it the highest point. Then you have a smaller line tap into the highest point on the cooling system. A larger line goes to the inlet side of the pump using a Tee. bam you have a fill point, a bleeder system, and majority of your worries are over.

Of course you can still have pockets of air that might exists, so you could still need bleeders at high points. Top of Rad for example. That is why I now vacuum bleed all my systems, negative pressure helps remove all air from a system. Especially when it can only draw coolant back into the void.
