Loyd Carrier cooling question.

Rob Beale · #1 02-11-08, 09:51

Here's one for the team: A Loyd carrier has its engine facing to the rear, with the radiator rearmost.

What is the airflow direction through the radiator? Is it over the engine and out through the radiator?

Does this mean the fan blades have a reversed angle to the normal Ford V8.
If so does any other V8 have the same fan?

I dont know the answer, but my guess is that the fan still sucks the air through the rad, The fan will be more efficient that way. and your forward speed will have little effect on the flow of the air inside the engine cover.
Now I'm waiting to find out too.

Hi Rob,

As we own and restored a Loyd carrier we found out that the airflow goes from the engine through the rad at the back.
If you install an ordinary fan with the airflow from the rad to the engine, you'll get some serious headaches from all the fumes and crap from the engine inwards the carrier, very nice if you have the tarp on (NOT).

Good luck finding the correct fan,

Cheers,

Stefan

Thanks Stefan,
that makes sense, as the dust cloud behind would be drawn back inside the vehicle.

I had the opportunity to drive a Loyd on the weekend, and there was a long running discussion on the airflow direction. A fan with the opposite angled blades has been found (ex tractor) but it will need an adaptor made to fit.

It is about 1 inch smaller in overall diameter, but I think the rearward airflow will overcome any loss of efficiency at the fan tips.

Lynn,
the engine cowling is completely open at the front, with a wide spaced mesh. Possibly the wheeled Carrier has the same set up too.

The Ford Rear-Engined chassis used in the Wheeled Carrier has a normal rotation fan that draws air FORWARD through the radiator. The Wheel Carrier bodywork has a upward facing vent to draw air down into the radiator, and an open bottom to the engine compartment to vent hot air away. Although there is an access panel between the crew compartment and the engine compartment, there is no through ventilation.

As far as I can see on pics of the GM rear engined chassis (Fox, Otter, Rhino), the fan also appears to be a normal rotation fan that draws air forward through the rad.
