Superior Radiator Radiator+Fan LS swap Jeep LJ

[I Lean]

Volvo 850 electric fan is the answer. Say, 1996 vintage. Ish.

This is the one I got. It's very deep at like 4.5" and will likely require a different shroud than what came on your radiator. I'll be figuring that out this week. Stay tuned.....

This one is a puller. Cost less then the pusher. https://www.summitracing.com/parts/flx-105390

I have to seriously question the CFM spec. Look at the amp draw compared to the SPAL fans

Exactly

I don't think that mean much, nor that an indication that it's a better fan

How that fan worked for you?

Whatever you want to believe.

Here is a fan out of a 09 mustang 4.0L. Is this enough for the ls motor?

Based on displacement and HP of the 4.0, I'd say no, but you're also not providing enough information for anyone to legitimately answer that question.

No running AC. What other info is needed?

I found another fan out of a 2003 Lincoln LS V8 3.9L, end up buying both for $60.
Not sure if the Lincoln v8 fan will be better to run. It has 4 wires, power and ground, and 2 other small wires.

For me it’s working great so far. It’s probably the widest fan out there so fitting it is hard. My passenger side head is about 1/2” from the firewall. If you have more gap than that it won’t fit. You’d really have to switch to a car accessory drive system. I cut the nipple off my water pump to clear with a bit of a gap.
You may want to stay away from that 4 wire fan. I’m guessing PWM is a headache you don’t want. Try the other one. Shoot, try the fan that came with the radiator. It might work for you.

It's a decent brand, moves a ton of air so those are good... but you want a puller, not a pusher since your fan will be mounted behind the radiator.

No Way the fan will go behind, no room. Will have to push radiator forward

 

[mdbs14]

Here's the 16" Spal fan I used, it's rated for 2000 CFM, has a low-profile motor and it's a straight blade puller. It's not too expensive, but it is loud like @UNSTUCK mentioned... I should see if I can get a curved, replacement fan blade for it.

Possible to see an image of how the puller fan get mounted?

For the dash, just buy a nice sheet metal brake. Bonus if you can source a used one that is also a good sized press brake.

But your fan is in front of radiator. Per your previous post I was expecting it to be behind the radiator 🤔

two common OEM Go to's are the Ford Taurus fan and the Lincoln Mark8 fan. I'm gonna be running the bigger Mark8 fan myself but a few of the crew i run with use the Taurus fans including my past build and they have worked well for us.
