D1SC Fan Shroud question
D1SC Fan Shroud question I have a 02 Trans Am with a iron block AES 390 with a D1sc with FMIC. The problem I'm having is that driving around my temps are about 210 normal, but when I get on it or drive up around 80mph temps start climbing up towards 230 and then I either slow down or crank on the heat on the floor.
I have replaced the standard ATI fan with a Zirgo 16" that flows 3260 cfm. Temp got a tad better, but still can't run the air without temps climbing. So I just purchased another 9" Zirgo fan that flows about 839 cfm. I think it will help keep my temps at bay. My question is: Do I need to re install the radiator shroud? Or can I just mount the fans to the radiator?
I know most schrouds channel the air but in this instance it's just a flat peice of metal the fan mounts to. Which is a PIA to remove from the top, without pulling radiator hoses.
I have also drained the radiator and plan on putting in some new fluid.
Any insight is greatly appriciated!

I have two fans on mine with the shroud that came from procharger. I live in the desert and mine stays cool in hot weather but no matter what on red lights your temp is always going to creep up somewhat. I would check to see if there is any bubbles in your radiator; crack the radiator open turn on the car and wait until your thermostat opens then fill it until its full.
Well, it's currently drained completely, I'm going to flush it out, along with hoses and storage tank and put fresh antifreeze in. So should I put the fans on the shroud or just attach them to the radiator?
did you put the shroud back on underneath...the plastic piece that would normally scrape in those pesky driveways. it diverts air over the radiator etc....and I hear tell that leaving it off, can cause this. I was not planning on -putting mine back on, but looks like I will have to, but I am getting a new one since the old one has seen better days. just a thought.

Yes it was installed. They cut it like it says to in the installation manual. I brought it to work today and I'm improving on the design and building one out of aluminum.

What temp T-stat are you running. You could try a 160 stat while the coolant is empty if you don't have one. Also are you sure the fan is pulling and not pushing. When I installed the procharger supplied fan and wired it up per their directions it was pushing. Car would heat up when moving and then cool off at stop lights.

and I have also added 2- 12 inch pushers in front of my ac condenser to keep mine cool. It kinda seems there is alot more overheating issues with fmic's but I dont know. jeff
I agree, you want the shroud. Bob

I do have a 160* stat, I have the lower airdam, and the fan is wired correctly. I guess I will add the 9" Zirgo fan to the schroud, put in new coolant and see what it does. Thanks for all the input.

just my thoughs on it though, not sure if you could test it with and with out and see if there is any difference.
Well, brought the shroud and two fans to work today. The housing on the 16" Zirgo fan is larger than the stock ATI fan and won't allow enough room to mout the 9" also. So I'm going to have to make a new shroud and see where I can move the fans to get them to fit.
I disagree. The fans outer edges are against the radiator, so any air it is moving has to go through the radiator. With the shroud in place any additional air movement that would go through the radiator would be stopped with that big metal shroud. With out the shroud air can go through radiator at any given point plus have the fan pulling air through it.

The shroud gets the fan out away from the radiator thus drawing air from the entire area the shroud covers.
Well, I was able to get a new schroud fabbed up yesterday after noon at work. I can mount both 16" Zirgo fan and a 9" Zirgo fan and still have room to clear the Procharger Hat.
The outside diameter of the fans is quite large compared to other fans that I have messed with. But according to thier specs pull more air with less draw on the electrical system.
