Radiator for BJ40

[recyclingthepast]

been searching for a radiator for a 1978 B engine- did see in one post that the fj40 rad is the same? Anyone got any ideas? also the water pump, and hoses-

thanks

I believe they are not the same ,ie inlet and out lets are not in same position so you will have to reweld/position them??

The B-3B has upper and lower hose on left side, the FJ40 has upper hose on Left side and lower hose on right side, you can make it work with a thick gauge flex hose or get B radiator. I have never been able to find a 4 core BJ4x radiator so I went with a 4 core FJ40 radiator and used the flex hose across bottom of rad and then regular hose.

Possible a radiator from and H Series might work, but I am not sure anyone with HJ4x or HJ4x troopy know for sure?

Cheers,

Michael

See post number 56 in this thread (Might be some help.):

Do you want me to take photos of my spare B engine radiator?

the 3B has two different rads although both have the outlet on the lower left.
the earlier 3B with no PS has the inlet upper right side
the later 3B has the rad with the inlet upper left side
gasser do not have the same configuration they are lower right upper left.
the HJ is lower right and upper right

for interest sake, the 1HZ swap uses the gasser rad.

you could go for the 1981/82 3B rad and make it work, it 'should' be a straight bolt up but minor changes 'might' be needed (said this to cover my ass)

a good rad shop could probably move the inlet from the later 3B over to the other side if the earlier 3B part number is dead.

Years refer to the cruiser, not the engine, i believe.

My 3B is an 82 with PS (out of a 1983 BJ42) and it has upper left, lower right.

It is an 'earlier' 3B with the downwards-facing oil filter and in-line injection pump.

3B without PS vs 3B with PS is the deciding factor

 

[eleblanc]

If i remember mine are both on the left side, and i have a PS.

Check spectra premium, they do have radiators for the BJ42.

PS moves the rad inlet over to the other side so the thermostate housing can clear the PS pump...

Thank you for a concise and friendly response .

I reread your post and still find it confusing.

You recommended a 1981/82 3B radiator, and you seemed to classify 3Bs into 'earlier' and 'later' groups based on wheter or not they had PS.

I have an 'earlier' 3B (commonly identified by the upside-down oil filter) with PS that didn't fit the classification I percieved you made.

So, your advice for the 1981/82 radiator could have resulted in selecting one that had PS.

Long winded but at the end of a bad day it's the best I can do.

 

[crushers]

if you have PS then you will need a rad with the inlet on the upper left since the PS pump occupies the RHD side so the thermostate has to go over to the left to clear it...
16400-56101 or 16400-56111

clear as mud?

 

[lostmarbles]

These are part numbers from the last time I replaced these items:
Water pump: 16100-59055
Heater control valve 87240-60030
Coolant hoses to/from oil cooler 15777-56010 and 15778-56010
T/stat to water pump outlet hose 16261-56012
Water pump to coolant-line-parallel-to-rocker-cover 87245-30331
Lower radiator hose 16572-56020
Upper radiator hose 16571-56010

But that was back in 2000 & the items were purchased 1 or 2 years earlier



PS. And here's a photo of the spare radiator for my 1979 BJ40:

I have a very nice clean used radiator off BJ40 for sale.

thanks everyone for your posts-been on a job- the engine is a B- that is what the sticker appears to be- no powersteering and since a 3b appears to be easier to get i am gonna look into that for now any possibly have it moved- or doing the long hose trick= any pros or cons on the longer hose??

american psycho you must have your rights and lefts mixed up. I can see from the picture you posted of your engine that the upper rad hose comes out of the right side. I have the non-PS early 3b and it is on the left.

I think your differentiation of "early" and "later" 3b's is a little off in this case too? I thought the 3b without the inline injector pump was the 3bII or something and came only in much later models. I think any 3b you find in a Canadian bj60 is going to have a down-pointing oil filter and inline injection pump, but if it's older than 82 (1/2?) as Crushers says you will not have PS and your rad hose will be on the left. Also, I think the t-stat is different, which makes sense with the different housing...

Someone please correct me if I'm wrong as I don't "KNOW" all of the above, but it is what I've gathered...

Also you mention that your 3b is an "82 out of an 83 truck"... how is that? I think perhaps there is a confusing sticker on 3b's that says 82 (that maybe doesn't relate to year?), because mine as far as I know is out of an 81 bj60 and has a sticker on it that says "82"

Well this is the wierdest thing! All I see on this thread is the first paragraph of your post put when I click "quote" to reply I get to see two more paragraphs as shown here??????? (Edit - Now I know why..... You were editing as I was replying!)

Anyway - I can see from his photo that his upper hose come off the lefthand side of his radiator. (But then I live south of the equator.)

Edit - The convention is that "Left" and "right" designations are always given as if you are sitting in the driver's seat.

 

[joshoisasleep]

hummm that's funny I've only ever heard it referred to my way? The FJ62 has it coming out the right (facing the truck if you've got the hood open), and the old bj60's are coming out the left. If you're sitting in the drivers seat, you can't see the rad hose.

Yeah I tend to add to my posts after I post them...

 

[recyclingthepast]

still looking for a bj40 radiator for a "B" engine- just wondering if anyone came up with any ideas-

thanks
