Re: 1940 fan shroud
Nope! But there was baffling on the front side of the radiator to help direct air flow through the radiator. DD

Re: 1940 fan shroud
No original shroud. But I fitted a walker plastic shroud to my 41 pickup. You have to measure and cut the hole, but it works well. I found a few threads on here about others who did the same.

In addition to the side shields on the radiator, there was a lower pan below the radiator as well as a left and right "engine" pan. These all should be in place for proper air flow beneath your hood. You shouldn't need a shroud. If a shroud is installed and helps, there are underlying issues that have not been properly addressed.

Re: 1940 fan shroud
Mike, Can you post a picture of the side shields. Mine might be missing.
Thanks, Phil |

No issues, just trying to make sure all is where it should be. I have a bucket of parts that I do not know where they came from and I am trying to work it all out still.... |

Re: 1940 fan shroud
My 40MERC has a hot air heater with a shroud and pans. My 39Ford has a shroud from a 38 dump truck

Re: 1940 fan shroud
Here are three photos depicting all of the shields required. The side shields for a 60HP are different than those in the attached photo.

Re: 1940 fan shroud
Hi Phil,
They fit between the grill louvered grill parts and the fenders. |

Re: 1940 fan shroud
I found them. Just never noticed them before. Wouldn't it help to add an additional panel to the top side of the grille like the shoeboxes have? There is even a bolt on the upper member going nowhere. As it is, there is a big gapping hole over the grille that will send air up under the hood instead of through the radiator. I see panels are for sale for the top for about 100 bucks.

Re: 1940 fan shroud
Make 2 thin sheet metal, smooth hardboard etc. panel that you can tuck up inside the nose of the hood. Mine are held in with a dab of silicone glue. been there 20 years. I only painted one side.
Doing this, you don't need to buy that $100 piece. Last edited by 19Fordy; 08-14-2020 at 07:52 PM. |

Between the pan and frame, a small piece of duck cloth was installed to prevent rattling. That can be purchased at any fabric store. You'll need to remove the pitman arm to install the left pan. To install the right pan, you'll need to remove the exhaust pipe.

Re: 1940 fan shroud
I know it's not the correct OEM thing to do but you can install the panel that goes around the pitman arm if you make a hacksaw cut and flex it to fit. I also made a little sheet metal clip that was installed afterwards to secure the kerf. Sure beats pulling the pitman arm.

Actually, if you do decide to use the panel, make one out of thin sheet metal like the stainless piece, paint it the color of your car so it doesn't look like an obvious add on. It looks better when you open your hood and don't see that stainless piece on top of your grille. You want it to blend in. But, that's just my thinking. I never did any before and after temp checks regarding the panel I made. It would be neat to see a wind smoke tunnel test showing how the air coming thru the front grille circulates and flows through the radiator under the hood and then exits for new incoming fresh air. Wonder if anyone knows? Last edited by 19Fordy; 08-20-2020 at 01:01 PM. |

Re: 1940 fan shroud
I made a set from 1/16" poly. painted with product good for plastic. Two small sheet metal screws are all I used to hold them in place.
