Cooling Solution for early (1984) cars.

Alan, mine has the same set up.  I never had any problems although I do not recall sitting in traffic much which is when it will be needed.  Apart from fitting a larger fan in front of the rad (which will be more of an obstruction to air flow when moving) there is not much option with a Xflow that I can see

Hi Alan,

We have the same setup on our car. Do you have the shroud that goes around the fan? This will help somewhat, but still a pretty dated design. There is not a lot of room on the back of the radiator for a fan either. We are considering an aluminium replacment radiator and would try and fit the largest fan possible on the rear (as the oil cooler and ARB are in the way on the front). You should get a decent sized fan mounted to the rear of the radiator, above the steering rack.

Hiya, long boring story but here in australia its a tad warm, albeit my cars a bit different, K series.

 I went radtec radiator (excellent) 10' fan on front with a  relay and switch on dash, then used the original thermo cut in fan on the back, with a flat carbon sheet cut to be a very close fit and mounted on the inside, in effect it ensures that the thermo fan works at maximum efficiency and draws air across the entire fin surface not just the fans diameter. Along with a couple of other things car runs all day steady temp, 80/85 degrees in traffic/ track days warm down lap I just nudge the extra fan and its a dream.

Makes sense but definitely research cooling radiator shrouds, very convincing when you look at the physics of it, I guess there's a reason why all the major manufacturers waste tons of invaluable underbonnet space with elaborate shrouds.....I chose carbon sheet as its relatively cheap, (ebay) thermally efficient, fairly easy to work with (watch the dust - think asbestos!) and looks good when done neatly.

Hi Timb2117,

Do you have any further details or photos on the radtec radiator you used? was it one of their off the shelf models?

Where in Australia are you based?

Chris

Alan,

I would imagine someone removed the fan shroud to save a bit of weight as it seems to be made of quite a decent gauge thickness of steel! I will be interested to see photos of your final solution

Hi Chris literally off shelf at demon tweeks, phoned had a chat they were very good and it was here in Brisbane in bang on a  week, fitted perfectly first time, side pass (tanks on sides not top and bottom)

Price cant quite remember but it was cheaper than having it locally made up.
