What's in the Box

Info

Maximize your radiators effectiveness with a tight-fitting fan shroud. Use of these shrouds has produced temperature drops of up to 30 degrees!

Walker shrouds are vacuum formed from a very dense polyethylene. This high-impact, heat resistant material has a lightly textured, semigloss black finish. The cooling fan hole is not cut out so the installer can tailor that to the exact fan location and diameter.

See Application tab for application information.

Converted 1940 Ford and 350 from electric fan to engine fan

October 30, 2015
The end result was excellent but I noted that the plastic re-welded just behind my jig saw as I was cutting out for the fan. This required a second pass at slow speed. Recommend using a wide kerf blade when you cut out for the fan. I also needed to trim down both ends of the shroud to fit in the allotted space on the specified radiator. These were minor issues overall and the final result is excellent. I was converting my Ford from a front push type electric fan to a rear pull fan which is more effective (and far more quiet) To make the system work a little more efficiently and get the fan nearer the center of the radiator, I raised my radiator 1 inch and moved it 3/4 inch forward to achieve the proper fan clearance. The end result is efficient, reliable and looks good as well.
Pros:
  • Final Solution Worked Wel
Cons:
  • Some Minor Fit Issues
Yes, I recommend this product.

Fan shroud definitely reduced my engine

September 11, 2014
The fan shroud required extensive height alterations as well as reinforcement to keep the mechanical fan from making contact with it at higher RPMs. I have a 1940 Ford Deluxe Coupe with a small block (350 cu. in.) Chevy engine in it.
Pros:
  • i would purchase it again.
Yes, I recommend this product.

The core opening on the shroud is 16 x 21 ¼ plus the flange for mounting. The shroud is bulged to accept up to a 17” fan which would make the fan larger than the core dimensions on the radiator and be a readily available mechanical fan. The Shroud will need minor modifications for fan clearance if going larger than 15”

The dimensions listed on these shrouds are width and height of the radiator. The mounting bolts pass through the support channel on the side of the radiator. These fan shrouds have applications and also dimensions listed which might help you choose the shroud which will work best for your radiator.

It is possible that this shroud will work for other applications than what is listed. Compare the specs listed on the shroud to determine if it will be a good fit for you.

How does this attach to the radiator? My Walker 497-1 radiator doesn't appear to have a flange for mounting

On the radiator the side straps that go between the upper and lower tank on each side can be drilled for attachment of the shroud via 2-3 screws per side. The core with the coolant sits inside this side strap and taking care not to slip while drilling the holes and damaging the core is important. On our website you can see the shroud mounted with 3 silver headed screws per side.
