So today I replaced my factory radiator which had the dreaded crack at the bottom end tank of POS plastic unit. I ordered my CSF 3328 (aka Stillen Performance Radiator) from AutoPartsWarehouse for $304 shipped to Cali. I won't go through the nitty gritty of the install steps as the existing posts on there have more than covered them and covered them well. I will point out a couple things I ran into. First for some reason during disassembly I noticed that the passenger side post on my AC condensor was not actually being secured by the upper mount on the radiator. After putting i the CSF unit it sits the same way so I'm not terribly worried about it but it is weird. Next my external trans cooler did not fit into my CSF unit. It slid into the brackets on the stock unit and the holes lined up perfectly for the bolts but on the CSF unit I got when the cooler was fully seated in the lower bracket on the CSF unit the bolt holes were too high. I took care of this by grinding back on the cooler's lower mounting bracked to make it sit futher down which brought the upper mounting holes were they should have been. First I'd heard or seen that so thought I'd share. While I had the radiator out I took the time to replace all the transmission cooler lines from the front end of the hard line (under the truck and just behind the radiator) as well as the upper and lower radiator hoses and the expansion tank hoses. I decided to ditch the factory pinch hose clamps (which I despise on several levels) and went with standard worm drive hose clamps at all points. I used factory Nissan upper and lower radiator hoses and the factory Nissan expansion tank hose but went with some Dayco 5/16" External Trans Oil Cooler hose from the local Autozone. I ended up using just under 5 ft of hose to do all the different lines. I also filled up the new radiator with some Peak Extended Life 50/50 and two bottles of Redline Water Wetter as well. I just recently had replaced by serpentine belt so didn't need to do any work there although if you haven't dont it yet and are going to replace the radiator its the PERFECT time to do this. Enough blabbering from me. Here's some pics of my install. Any questions please ask em.

Last 5 pics including some of the truck in its current state. Took it for a nice car wash after the install. Hope you enjoyed.

Same here. Did mine last week, and ran into the same problem. Quick fix with the grinder...but a hacksaw would have sufficed.

Same here as well!

I bought 6ft, and only used 5. An FYI for the rest of you guys, in case you're wondering how much to buy. It was $2/ft, so no big deal.

Good to hear I wasn't the only one on the trans cooler bracket. I figured my truck was jut the weird one again like it always is. Also good to confirm I didn't under or over cut any of the trans cooler line if you used the same amount as me. Congrats on the install. It wasn't terrible but got a little annoying at times when I didn't have an extra set of hands.

Has anyone had to cut the fan shroud so it fits closer to the radiator? I just installed one in my 06. Under normal driving and even heavy footed driving the fan did not rub. When the engine was under heavy torque the fan blade would rub in the front of the shroud, not the sides like you would expect it to with a bad motor mount. The fan blade actually broke and got thrown it into the radiator, ruining it. I had just replaced the fan clutch with a factory Nissan one at the same time as the radiator install. I thought I read somewhere that someone had to cut the shroud. I didnt because at the time it wasnt hitting anything. When it was all installed there was about a 1/2-3/4" between the fan blade tips and the fan shroud.

No I didn't cut mine. I noticed the same thing though that the shroud doesn't sit completely flush but didn't see any issue with the fan hitting on mine. I towed my boat out to the lake this weekend and didn't have any issues with it hitting

Ok comparing this CSF 3328 radiator compared to the stock Nissan radiator, the mounting locations moved in 1" towards the fan blade. This is based on the pin bolts that go in on the top and the bottom pins that fit into the radiator support. That difference is a 1/2" when you cut the fan shroud to move it back in towards the radiator. Not cutting the fan shroud, puts the blade in touching distance to the shroud, especially when you add in fan blade flex. Reason? Poor engineering on there part, or is it to maximize cooling?
