I did a search for the answer to this because I know it has to have been asked in the past, however, I couldn't find it.

I need to get a fan shroud on my car before it's first 10 hour one way trip to Biloxi, MS. How do I determine what size shroud I need? It is an original FoMoCo radiator.

If you let us know your engine size and whether you've got AC, we can tell you the "right" shroud for your application. Or you can go with a '69 service part. I've been keeping my eyes open for the original '68 302 AC 4V shroud for a year now, and folks keep telling me to go with a '69 service part replacement.

My engine size is 289 w/o AC. I may put A/C on later but it will not be factory.

Look at the back side of your Radiator and measure from flange to flange it's either a 20 1/4 inch or 24 1/4 inch Radiator.

odds on you have a 24 in and the reproduction shroud will run appox $65 - 75 plus shipping.

My 66 mustang is a 302 with A/C, automatic trans, and has a hipro radiator. The fan shroud is very thin and I hardly feel it will make a difference to have it on. It maybe sticks out 2 inches? Is this going to help cool the engine really?
I have it off right now.
Thanks.

Well, here is my two cents. If the shroud wasn't needed, Ford wouldn't have put it there. From a technical standpoint, it greatly increases the airflow into the radiator which helps to cool the engine. I have got by without one for 2 years now, but I would feel better if it were there. At least I could know for sure that an adequate amount of air was flowing through the radiator.

A shroud will make a huge difference , you may want to get one that sticks out 3 to 4 inches ( after market available item ). Your standard pully attached fan is really only good til about 30 to 40 MPH , after that it is the forward movement of your car that forces air through your rad. At an idle or low MPH the fan , shroud and hood work together to direct the outside air through your rad. A six bladed flex fan will also really help cool you down

Does this mean all the cars came with shrouds from the factory? Mine is without a shroud and I thought it must have come that way. I thought shrouds were an "add-on".

I have a 68 coupe with 289CiV8 and a C-4 auto. My engine does run pretty hot especially at lower speeds. time to get a shroud?

No , not all cars from the 60`s and 70`s came with shrouds , for some of them it was a dealer or factory option add-on


Get a shroud , can never go wrong with one , also a 6 bladed flex fan. Would not be a bad idea to check your rad for some blockage , water pump working O.K. ? Check that your thermostat is working O.K., what temp stat are you running ? Something else to remember is that your tranny fluid is also going into your rad ( at the bottom in the small tranny tank ), this will also heat up the water in your tranny a little bit. Don,t forget to check that your temp gage is also working O.K.

oh I didn't know what was original, haven't had one on the Fairlane I drive, just ignorant. not one one the 67 mustang either.(technical I am not!)
thanks, though. I can put it on,no problem.

Forgot to say I do have a 6 bladed flex fan also. I have experienced high temp at low MPH, and went through all the items you mentioned in the cooling system and only found what I didn't think would matter...one of the transmission cooling lines was pressed right against the lower radiator hose, causing a small indention. I have new waterpump, good flow on the radiator, 185 thermostat, so I re-routed the cooling line.
Haven't driven it lately-rear end went out.
Thanks for the input.

If its a non A/C car it would be a 20" radiator(I think). Most non A/C cars I have seen did not come with a shroud, but luckly the non A/C shrouds are much cheaper than the A/C ones. If you plan on adding A/C later(after market or stock) invest in a larger radiator and a shroud to fit it and a 6 blade fan. Heck, pick up the fan either way you go. Extra cooling never hurts

Get the shoud it will make a great difference
