Guys I am thinking of buying a PWR alloy Radiator with a single 16" 2000 cfm fan for my LS2 in my LH
I would like to know your thoughts before I make up my mind and out lay any $$$
If any one has a pic of this set up and how it sits would be great

Cheers Kevin

How's clearance? The front of the LS engines is bulky. I had to go twins on the LJ as I couldn't fit the hub of a big single in the centre of the radiator.

Thanks for the reply Rexy
I spoke again today to the guys at PWR and they assured me that it would fit with the measurement that I gave them ...
PWR Radiator is 70mm thick and fan is 88mm thick so a total of 158mm
And I have 182mm between the Rad support and nose of the water pump
So if I have done my maths correct there should be 24mm between the fan motor and water pump nose

Is the radiator a downflow or a crossflow radiator?

 

I did have a PWR crossflow radiator with a 16" SPAL fan. The radiator fitted with plenty of room but the outlets did not suit my setup so I ended up changing to a downflow radiator with twin Derale 2200 cfm fans.

 

 

You will find some other pictures here.

i might have this wrong but whats with running more earths to radiator.is it something about current,cant actually remember what is was

[ls2lxhatch]

Aluminium radiators are more susceptible than brass/copper radiators to corrosion caused by stray current from faulty electrical components.

 

Some tech articles recommend grounding the radiator and others recommend you do not ground the radiator. There seems to be more support for grounding the radiator.

 

They all agree that you must use appropriate coolant and test for stray current regularly using a multi-meter or dedicated device (Koolit Indicator). If you find current in the coolant then you have to find a fix the electrical component that is causing the problem.

ls2lxhatch.....Radiator is a cross flow design

[BIG KEV]

I will have a look and get some photos of mine tomorrow. Mine has a 4 core Ausie Dessert Cooler with twin thermos

Also there are different pulleys for the front of an LS. It may depend on which one you have.
Mine is different to Rexy's

Grant ..Rexy's pullie looks like a ls1 set up
My motor is ls2 but I converted all the bolt on's back to ls1

ls2lxhatch.....Radiator is a cross flow design

 

I thought it might be as the 16" fan overhangs the Torana  down flow core. The typicall  cross flow core (2444 cm2) has a slightly larger area than the downflow core (2340 cm2) but more of the down flow core is exposed to airflow than the corse flow core.

 

 

 

I went with the down flow core as the location of the transmission cooler suited my setup better and I could run more fans with a decent shroud.

Andy I am planning on buying the cross flow design with just a single 16" 2000 cfm fan the 3000 cfm fan needs a 60 amp fuse and I only have 2 30 amp fuses in my new wiring kit ,by the way I don't have room for a shroud
what are you guys doing about the air bleed line from the front of the heads
I have heard that you can drill and tap into the top of the water pump
any ideas ????

Nice rads! Expensive but the quality is there. 

I am running the same set up on Purple. It fits nice with the 304. 

 

Does it work? I don't know yet ..... but soon.

It is common practice to connect the steam line to the top of the water pump. You have to wonder why it is not done this way at the factory.

The only difference I can see between connecting the steam line to the water pump instead of the radiator is that the radiator is that the radiator is typically higher than the heads so the system will self bleed.

I connected my steam line to the top tank of the radiator as it was simpler for my setup.
