Fan shroud on 70 CJ5?

I think we discussed this some time ago, one is 17 or 18", the other is 22"? Not sure which is which, but I do remember the thread Jim is talking about. Seems like the Commando version did not work after all.

 

May I speculate? Maybe the new grille for the Jeepster (ca 1965) allowed a wider radiator. A wider radiator on the CJ would require a redesign of the existing grille.

 

There is a simple solution to this debate, call the guy who I said is making the shrouds and ask him to give you some dimensions.

 

beeser did that some time ago....we're waiting for him to catch wind of this thread

 

The 70 and 71 model cj has the wider grill box and radiator. Patrick and I compared our 2 radiators and grills at Tellico.

 

Soooo....you were all up in his grille?
<rim shot>

Beeser bought the fragile V6 shroud I had and he said it didn't fit or something like that. Hope he chimes in.

 

good luck getting one. Just make sure someone didn't change the radiator for one of a dif. engine. I just got sick of the fan and went to electric pusher mounted on the inside of the grill. I believe you can buy a radiator for about four hundred bucks for the v6, but good luck finding the shroud, no one makes it that i know of.

 

My cousin recently bought the last Jeep NOS shroud for his '69 from the dealer in Aspen.

 

I don't know, never seen a Jeepster to compare it with.

 

Hello all you CJ5 guys, I know this is old post but I was searching for a photo of a CJ-5 fan shroud and ended up here. It's amazing what you find on the internet especially when you find yourself in the search. My name is Don Fletcher and my business is Partsdude4x4.net formally www.jeepsterpartsdude.com. As you can see, I no longer just supply Jeepster Commando parts, I’ve expanded my site to include Willys, Kaiser and AMC model years. As I read through this old post (wish I was following back in 2006), lots of questions on the Jeepster shroud fitting a CJ-5. The Jeepster shroud measures about 21" across and the early CJ is about 17 1/2" across. I finally found a CJ-5 shroud to make a mold out of but it was missing about 1/3 of it. I worked with the fiberglass company that produces other parts for me including the Jeepster shroud and was able to build a prototype shroud from what we had to work with, I’m ready to test it on one more Jeep.


I attached a photo of the shroud installed in a CJ-5. Because theses need to be a perfect fit, I need really good feedback on the changes, I need one more jeep to test fit the shroud before moving into production.

I need someone willing to test the prototype in their jeep and provide me with feedback on the fit with photos, in return I’ll send you a finished shroud. I would also need your permission to use any photos you take on my web site. Best way to contact me is e mail
partsdude4x4@hughes.net

Only need one person for the R&D

I can have these available in a month if I can find that CJ-5 owner that can give me a quick feedback and photos on the shroud. This is the 1st part I’ve ventured out on the manufacture that was not related to Jeepster, I have many of those models to test fit my parts on. My wife tells me I will not be buying a different model jeep every time I want to make a part for.

If anyone has a photo of the original shroud out of the jeep and one installed in the jeep that would also be helpful posting.


Thanks for your help

Try hosting through photobucket. I dont see a picture.

 

As was posted further back in this thread, there's two different versions of the v6 radiator. So,it seems to me you'd need two different fan shrouds to cover all years.
BTW I have a shroud on my 70 and it really helps with cooling.

 

I have the jeepster shroud I've been making for a few years now (21"), the new shroud is for the small radiator (17 1/2"), are you saying there are two shroud sizes for the early CJ-5?


My experience with adding the shroud to the Jeepster is 20-30 degrees cooler

 

This is the post I was referring to. I dont remember the exact difference, but the radiator did change in those years.
BTW I totally agree with you on the effectiveness of a fan shroud. Mine made a tremendous difference in airflow on my CJ.

 

Hey Don,
I bought one of your Jeepster shrouds about 3 years ago, and I am running it on my '70 Yellow Barn Find. It fit pretty good, but I did need a little clearance cutting for the alternator pulley.
This is a poor picture, but you can barely see the clearance notch I spoke of...

Don, thanks for the post, I might have to drive over to Rio Linda so you can show me how to post photos on the site .

OK, post update. Thanks to Brent Johnson and his CJ 6 for testing the shroud. Brent took some great photos of the test, I tried to use the "insert image" tab with no luck. I have a word doc with photos if someone would like to post this test with the photos, PM me your e mail address and I'll send it to you.




Here's the write up

Installed in the engine compartment of a fully restored 1967 Jeep CJ 6 with a 225 V6. The original clutch-fan had been replaced by a previous owner. In place of the original fan was a flex fan with a spacer that brought the fan approximately 1 inch from the radiator. At idle, with a 165 degree thermostat, the Jeep water temperature would climb to approximately 200 degrees in cool weather.

On the edge of the radiator the tab to mount the fan shroud is clearly visible. Since I did not have the original fan, the first thing I had to do was measure the size of the flex fan to ensure proper fitting with the new fan shroud. Also, since the fan shroud did not have the mounting holes pre-drilled, I had to determine if it was possible to measure and drill the mounting holes without removing the radiator. I determined everything would fit, but the radiator needed to be removed to ensure a good fit in the drilling and mounting of the fan shroud to the radiator.

I drained the radiator by opening the petcock, un-hooked the top and bottom radiator hoses, unbolted and moved the support rod. Finally, I unbolted the four bolts that held the radiator in place to the front grill. The top radiator bolt on the driver’s side is clearly visible just above the support rod.

With the four bolts removed, the radiator was separated and removed from the grill, I was now ready to go to my bench top and drill the mounting holes in the new fan shroud.

I fit the fan shroud to the radiator and marked the holes from the inside using an awl. I then drilled the holes. I used the identical procedure for drilling the holes on each side of the fan shroud. This photograph shows the fan shroud resting on top of the radiator and the alignment of the holes. As indicated, some indentions on the fan shroud do not exactly line up with the factory location of the holes on the metal tabs of the radiator. Since I had completely rebuilt my Jeep using stainless steel hardware, I decided to use stainless steel. I skipped using a sheet metal type screw and instead installed the fan shroud with six ¾ inch long, #8 button head stainless steel bolts, six #8 stainless steel washers and six #8 stainless steel ny-lock nuts (the total cost of the stainless steel hardware was about $5.00). I determined because of the location of the holes on the mounting tabs of the radiator, it was best to mount the bolts from the inside out.

I then reassembled the radiator to the grill in the opposite order that I used when I removed the radiator.

After the radiator was reinstalled and all hoses hooked up, I replaced the coolant in the radiator and started the engine. I allowed the engine to idle for 30 minutes while I checked for leaks. After 30 minutes of idle, the engine water temperature only raised to 175 degrees. Therefore, with the fan-shroud installed, the water was over 25 degrees cooler at idle, a big improvement. From start to finish, the job only took me about one hour to complete.
