The difference between the 5.9 efan/shroud and the 5.2 shroud is the 2 mounts under the radiator cover. When I did my efan I had to cut them I recall. The efan/shroud doesn't need the brackets for the 5.2 shroud, it has it's own integral brackets.

I thought the efan clipped into the square holes on the tabs that protrude from the bottom of the rad.

Right, the same as the 5.2 shroud does.

I think, somebody with a niner back me up here.

Sorry I'm a bit confused I thought you just said they were different. Maybe I'm reading too fast

The fan shroud has two clips at the bottom that slide into the radiator housing then bolts on the top.

The bottom of the shroud has two prongs that slip into the slots on the bottom of the radiator. The top of the shroud has two brackets that connect to the mounts on top of the radiator.

So the top mounts differently between 5.2 shroud and 5.9 efan/shroud. The 5.2 brackets are part of the mounts and 5.9 brackets are part of the shroud. What I am wondering is if the lower tabs on the radiator are different between radiators. I don't think so.

The rad I got from rock auto didn't have a spot for the e fan "prongs". I zip tied the hell out of it though. It's a work of art.

I think I know what you mean now. Didn't know you meant the top brackets before. Either way I want that silla. Might have to call silla themselves and get a price. Hope it's not too absurd. On their website I also see a two row all aluminum that says available soon.

Informative thread. My trans cooler is plumbed after the rad warmer/cooler and temp sending unit plumbed in the outgoing trans line. Sits around 200-205 on hill climbs. 180ish on the freeway. Think a Silla rad may be in my future.

Don't fear the regear.

Finished 4x2 --> 4x4 conversion.

Here's what I'm talking about with the fan and shroud mounting. You can see where I cut the bracket off. Crappy uneven cut, can't miss it. The niner efan has the brackets attached to the shroud so the 5.2 brackets are just in the way.

The trans cooler fan came in. I started the project even tho the temp switch won't be here til Tuesday. I hooked the fan up to a 12vdc power supply and I was amazed at how much air this little fan moves. Out of pure luck and nothing I planned , I'm able to pull the trans cooler up and away without removing too much. Grill, fan, shroud, and radiator cover so far.

A tip for removing the fan and shroud: once you get the fan clutch unbolted from the water pump without mangling your radiator, remove the radiator cover and move the radiator forward. The fan and clutch will come right out the top. Then you can pull the shroud up.

So that 30,000 GVW cooler has kept my trans oil temp at around 150*. After about an hour or more of driving it warms up to 170*- 180*.
