radiator mount; What keeps the radiator in place?

I bought a new grille from Kaiser Willys (MD Juan). I pop riveted the shroud to the radiator (after this pic was taken) but I can't see an obvious way for the grille and radiator to be connected together. It looks like I will have to fabricate some brackets.

Do the two tabs off the front crossmember support the radiator?

My grille seems different to what appears to be an OE grille in this picture - did the design change?

I'd be keen for other to post pics showing the relationship between the fan and the shroud.

Thanks, Marty

Here's a pic of my shroud, radiator and grill from my 1953 CJ3B.
The radiator is supported only on the grill.

Loks like MD Juan did not make that grille like they should have. The radiator should not mount to the frame but rather to tabs on the grille assembly like the one in the photo Don posted.

marty,
Did you save your old Radiator Guard (grill)?

At first, it seems to me you could remove the inner support from the original and replace the incorrect on the MD Juan version. That would give you the mount tabs you need. Ironically, the Radiator Guard is the one body piece that seems to outlast all the other body parts. No donors nearby?

Also, to give you the option of removal, the shroud uses 8-15 x 3/8" pan head screws to mount to the radiator.

Marty, sadly, the MD Juan plant quite obviously totally lacks any idea whatsoever of quality control, particularly when it comes to the type problems you are now experiencing with the repro grill, added to correct placements and sizes of mounting holes, etc., fender and windshield fit problems, and on, and on.

With your current situation, Juan designers simply missed altogether adding the flange on the grill that supports the radiator, no two ways about it. That said however, and with the exception of the new fellow in Oregon who is now reproducing 3B stainless steel body parts in a factory very near the Juan plant, MD Juan is the only other vendor who makes these parts.

As has been stated in a thread above, it wouldn't be all that difficult to remove the flange from your old grill and MIG it to the repro grill; or, you could simply weld (add on) four short lengths of say, 1/8" thick x 1 x 1, pre-drilled angle to the new grill to support the radiator.

Thanks Larry and Rus. Unfortunately, the grille my jeep came with didn't have the flange attached. the PO had made some support brackets and I will have to make something similar.

What's even sadder (than MD Juan's always lack of quality control on just about every product they produce), is the fact that the vendor, Kaiser-Willys knows very well this problem exists, yet they don't advise paying customers about it.

I'm aware that for additional money, they will perform additional work on most all MD Juan tubs, etc. that they sell, as our MV club VP bought a new 2A tub ftom them last yaer and they drilled out, re-alighned holes, etc. for a better mounting fit, so one would think they'd easily cure the 3B grill problems before selling them. Another serious problem is that many individuals buying these products don't know enough to ask up front about mounting problems before paying out high bucks for the item(s) - they simply assume that a repro part is (and very well should be) exactly like what came on the vehicle, thus there should be no problems when they receive the parts.

malcom,
Sorry, I don't know which configuration you're referring to. Can you post pictures of your radiator (or specify which image you're referring to)?

ozmarty62,
The radiator mount on your reproduction 3B grille gaurd was designed similar a CJ-2A grille gaurd radiator mount.
For some unknown reason your frame has the CJ-2A tabs on the front crossmember for mounting of the CJ-2A radiator.
Bottom mount radiators are of pre 1950 jeep design.
Because of these 2 problems you may want to consider installing a Jeep / Harrison bottom mount radiator.

Russ, I have those two tabs on the crosstube on my 3B.I installed the radiator I got from my PO [and had recored at no small expense]. It has two posts on the bottom [like a 2A?]
I'm fairly confused. I also bought a 3A recently and it does not have the tabs on the crosstube and the radiator was mounted on the sides.Posting pics to try to clarify.
This is the 3A, the trans crossmember is just resting on the frame in this pic.There are two small screw holes drilled and threaded into the top of the tube to hold grill.Posted Image Posted Image
This is my 3B. the bracket on the top tank for the "support rod" seems wrongly positioned. Is this the correct radiator? thx

I'm also seeing that my 3B does not seem to have the correct shroud.

malcom,
Let's go one deeper and say that radiator doesn't look correct for a 3B either. If you look at the images near the top of this thread and compare to yours, I believe you'll notice some differences.

Unfortunately, I don't have near the depth of knowledge on multiple models that others do here. Once they recognize what you've got stuffed in your jeep, they'll be able to suggest what it is you actually have.

So simply put the 3B did not have tabs on the crossmember for radiator mounting (unless the late models had a change). All the radiator mounts that were stock for a 3B should look like the images above posted by Don (his shows all three attached together).

Rus, I was looking at Ozmarty's picture showing the two tabs like I have. Wondering now if I have other than a 3B frame. Thanks for the consult. When
the temp gets above 0, I'm going out with my camera.
