I currently have a stock radiator that came with the donor car and I also have a brand new aluminium Desert cooler radiator but the problem with the desert cooler is that the outlet/inlet are on the wrong sides,

So I have decided to buy a new aluminium radiator but with all the options out there IÒ€ℒm so confused

So letÒ€ℒs start off with a couple of questions

What brands do you recommend?

How many rows do I need IÒ€ℒm thinking 3 but is it better to go 4?

The problem I also have is that the previous owner of the car has cut the radiator support larger so that now a standard size radiator will not bolt up in the original location, so what I have done is made brackets so a standard radiator will bolt up (pics will be up soon)



The next question is should I stick to a standard size radiator (65-66) or What size radiator should i go with (67 size)

I have been looking at this Champion Cooling Aluminum 4 Row

The number of rows with an aluminium radiator can be different to copper/brass.
I think its something to do with the manufacturing process, but some alloy radiators are only two core, but the cores are much deeper, so they give better fin area for heat dissipation.

Are you running thermo fans? I cut out the Donor EB Falcon radiator supports and spot welded them onto the edges of the chassis rails and the upper brackets to the top of the support, then used the original radiator and EL thermo fans. I figured that it all worked well when i was driving the Fairlane that used the aircon and towed car trailers so why change it.
You dont necessarily have to widen the current support cut out as the air will still flow to the sides of the radiator.
The only downside is there is less room on the sides for air filter and coolant tank if thats where you are fitting them.

This is how I fit the aluminium rads, bottom mount is a length of 25 X 50mm square tube that has some 1mm rubber glued to it.













I make slots in the back of the tie bar to help with more air flow ....

the bottom mount that is just welded to the support bracket, strut rod

what brand/type radiator is that?

The first few pics are when i mocked it all up before, the restoration, i am not using the coolant bottle, making up my own stainless one.









In this pic you can just make out the bracket on the left rail. Ignore the funny curved sections at the top, they are to house the Fairlane A/C evaporator brackets.

Top mount is a Galaxie mount attached to the described square tube. Bottom mount (again the 25 X 50mm square tube) has 2 studs that bolt to the strut rod supports.

Rad is a Ron Davis & I am buying a couple this US trip for boofhead & gbx78. It is a NASCAR rad.

Same rad in the avatar car. Top mount using a Mustang mount combined with the square tube .....

Mount an external cooler to a bracket in front of the radiator, as most modern cars do it.

I currently have a stock radiator that came with the donor car and I also have a brand new aluminium Desert cooler radiator but the problem with the desert cooler is that the outlet/inlet are on the wrong sides,



Firstly,
put the Desert Cooler on ebay. They are no longer made to the quality they built the reputation on, and for another reason which will become evident in my further text.


The stock radiator, will cool a 5.0 fine. Your issue of mounting it is easily overcome by replacing the radiator support. The issue of the outlet being on the wrong side, can also be overcome with off the shelf componants. Tho there are more parts required....early timing cover, harmonic balancer, water pump etc...... Then there is the question, of do you intend to run the serpentine belt setup...that also can become an issue.


IF you decided you didn't want to replace the rad support, and you are adamant on an aluminium radiator, then I'd reccomend a VR-VS 5.0 unit.

I am using one of these in my 302W powered Patrol, and its the 2nd best mod i have done. You can mount a V6 commodore fan to it, and seems to be dragging enough air through to make it work.
You will also find that the inlet/outlet are on the correct side for your engine. A V6 top rad hose works with some trimming...........forgot what i used for the bottom hose...will look tomorrow if i get time.


You also say you are going to run thermo's. what is your plan to control them?


Remember, that if you use something '1 off' then if you have a problem, you are stranded...............(extra from the desert cooler comment)
IF you can use common componants, when you have a failure, you will be on the road again so much faster.


As my sig suggests, i'm a panel beater, but cooling issues are something I have learnt a lot about through my patrol.....originally had a diesel radiator (modified) keeping it cool, and despite the extra 80% coolant this provides i struggled initially. Got it on the right..and practicle path now

how does the VR-VS 5.0 radiator bolt up, is it a fairly straight forward install?

most likely the standard way by using a thermostat dry-bulb sensor

im currently preping the engine bay for paint i need to make a decision quickly if i should go with a standard size 65 radiator or a custom/67/VR-VS radiator any suggestions will be appreciated

Not the greatest example, but you can see my tranny cooler in front of the radiator and aircon condensor.
