Thread: Fitting EL Falcon Thermos Onto Rangie Radiator

Hey Davo
I took mine off eventually - once the high South Australian summer temps hit, it just wouldn't keep cool. I am going to get the radiator checked to maker sure that wasn't the problem because it was much better with the electric fans but as you say the attachment point of the shroud left a bit to be desired. Having said that I have had a 4.6 fitted so there may be the need for a larger radiator as well to cure the problem, but it doesn't over heat with viscous fan

Hi Davo,

Can email pics, PM me an address. EL's in mine keep a 350 cool with a stock RRC rad.

Will be incommunicado after lunch today for a week.

cheers, DL

Ive got a Monster 5 Core Tropical fine core spare radiator to fit your model , in as new condition , that will fix it ! and you can run the standard fan / shroud combo if you wish . Going CHeeeeep !!!

I was thinking about this electric fan thing and I reckon you could reinforce the bottom rail with some angle iron to strengthen it and then swing the fans off that or maybe just swing the fans off a bit of iron rivitted to the crossmember below the rad. Or you could make more mounts up by placing a rivnut in the crossmember and then screwing a stud in to the rivnut then placing a rubber mount on.

Similarly perhaps you could make up a top mount that mounts to the bolts that hold the rad brackets but isolate from them.
You could seal the gap with a bit of Raven draught excluder.

The idea would be to have the fans not mounted on the rad rubber bungs as they would probably compress with the weight.

The common failure mode for cross flow rads is for the core to break away from the tanks due to impact and the inertia of the core. If the rubber bungs are compressed this can be made worse.

Spot on Philip.

When installing thermos on mine I noticed that the weight of the rad was on the side mounts rather than on the bungs on the bottom pins. Obvious potential for cracking the tank joints. I just packed the bungs so they took all the weight.

The weight of the thermo fans and shroud on mine is carried by simple fabbed ali brackets that go to the side mount points, no weight at all through the rad.

You are aware that the side brackets have slotted holes for up and down and side to side?
The easy way would have been to extend the relevant slot if the rad was out of range. The top mounts should hold the rad laterally and the rad should sit on the lower ones.
The bottom bungs wear down over time. I recently replaced all of mine, and they are the same as the top ones.(and cheap)

Thanks for all your comments, guys.

DL, can you post photos here? Or otherwise I'll PM you my email address. Let me know if you want me to post them.

Blitz, did you have the Falcon fans or something else? I'd be surprised if the Falcon thermos weren't up to it.

Philip, I did think about doing some of what you mentioned but at the end of the day the top and bottom shallow metal channels that connect the two side tanks are only attached to the tanks with some little rivets, so I can't see any extra weight not damaging them.

The other thing is that the radiator sits on those rubber bushes, and they are attached to the body, which also sits on rubber bushes. So you don't want a mounting that sits straight onto the chassis and has different vibrations than the rad and body.

I might take the trouble to make a steel frame that can take corrugations. Though I still can't decide where it would attach to.

Well I could not remember whether it is body or chassis. Hey but I AFAIR it is chassis because when you get a body lift you have to reposition the top brackets, so that the fan( on the chassis) does not hit the cowl( on the rad).
I will go and have a look. In any case, you can swing the fans off whatever it is that the rad sits on.LOL
