Topic: 3 row radiator dimensions..

Questions on the 3-core radiator for an 86....

I'm not looking for the core size or header tanks, but fore/aft mounting and size differences because I used the additional space in front to stuff in a engine oil cooler between the radiator and the AC condensor and I have an electric fan, so I don't have much room between the fan motor and the water pump pulley........

How much thicker than the 2-core?

Where is the additional thickness?
Engine side?
Or in front?   (the stock radiator isn't flush, but set back a little with some additional space in front.)

Basically, I might not be able to fit a 3-core  and I'm trying to figure out if it will fit with the electric fan and engine oil cooler.     
 

Help

thanks

the thickness of my 3 core is just under 2 3/4"  dont know my fractions very well

Ok, here's the problem.

The 2 row radiator core is set back from the flat portion of the mount.

I used that area to mount an engine oil cooler, and there was enough room in the mount to drill holes without touching the core as follows:






I then made a bracket to mount the fan on the fan shroud mounts on the engine side as follows:





The fan is flush against the core, and the mounting brackets allow me to not use the cheesy thru-the-core attachments, and allow fan removal without the radiator.

The clearance problem would be the fan motor and the water pump snout. (can't quite tell on second picture)


I core could probably move forward about 1/8-3/16" and rearward a bit (the core is recessed from the the rear fan shroud mounts too........)    So header tank measurements aren't quite enough info.

Yep, data transfer rate exceeded...........

I'll put up some smaller pics, and repost when it lets me...........

What does that mean? Heres a pic of my 2 and new 3 core radiators. I bought the 3 core from

Fixed, see above

Don't think you will have the room, mount the cooler in front of the condenser.

OK, just checked mine and there is 1" maybe 11/2" between radiator and condenser. But you will not be able to go through the radiator bracket with your oil cooler lines.

The actually core on a 2 core is 1 3/8" thick and the 3 core is 1 7/8", making it a 1/2" thicker. The mounting brackets on the side of the radiators are the same and the extra thickness in the 3 core should be to the front.

What I did on one rig was cut out and moved the radiator mounting holes on the body forward about a 1/2", but you might have to move your condenser forward also if the oil cooler is between them.

[hilux-1983]

I had taken one of my 2 cores down to the radiator shop and had them "unglue" the mountings from the tanks and move them so that the radiator could be moved forward and inch. Then I was able to install my "black magic" electric fan. The fan setup kept taking a dump for this reason and that so I took it out and got a refund. Went back to a mechanical fan and a new 2 core radiator. Finally to a 3 core.

No room in front of AC condensor

[emsvitil [OP]]

I figured out how someone could help...........

For those with a 3-core.

The thickness of the side plate:  front mounting surface to fan shroud mounting surface (outside to outside)

The distance from the core to the fan shroud mounting surface (inside to inside)

Thickness of core  (header tanks don't matter)


thanks

Do you think a notchs in the mount and the front chassis opening would work?

The cooler is 3/4", and with the angle aluminum and mounts it's about 1".     

So 1 1/2" still gives me some clearance.........

[DeadlyPeace]

The thickness of the side plate:  front mounting surface to fan shroud mounting surface (outside to outside) 2 15/16"

The distance from the core to the fan shroud mounting surface (inside to inside) 1/2"

Thickness of core  (header tanks don't matter) As I mentioned above 1 7/8"

Thank You, Thank You, Thank You     

I'll measure what I've got and see what can be done now......




A little more background......

7 years ago when I towed my Grandparents 64 Valiant from Pennsylvania to California.

(picture <-----  )

I only had 1 cooling problem.     

The hill outside of Needles to Barstow (110 degrees).     I had to turn the AC off and turn on the heater on and the needle stabilized at 3/4.    Everywhere else it never got above 1/2 even with the AC on.

In Barstow, I checked the oil level and it was down 2 qts.    It was ok when I had left Flagstaff, so I figured it burned off because it thinned out up the hill out of Needles.   (Normal burn rate of 1 qt every 2k-2.5k miles before and after that).

So when I replaced the timing chain a couple of years later with the LCE dual-row chain conversion kit, I figured I'd cool the oil to avoid any future oil burn off problem and add a little bit of cooling at the same time.


Anyway,  I've been having some intermittant overheating problems and the only thing I haven't tried is a new radiator.

So I figured I'd might as well 'GO BIG'

[emsvitil [OP]]

Ok here's the differences


.........................2...................3
Side mount       2.75               2.9375
core/shroud         .375               .5
core                   1.25               1.875

Derived
Front mount to
core                   1.125              .5625
Front mount to
rear core             2.375              2.4375
So the core is mostly forward.

With the 2 core there's about 1.375" from the core to the AC condensor.   This would be .8125" with 3 core.    Not quite enough for the oil cooler.

But if I mount the radiator closer to the engine with 1/2" spacers, I'll have the same clearance for the oil cooler.    The hoses would be a little trickier, but it's doable.

I currently have 1.25" between fan motor and engine belts,   call it a safe 1"

With the 1/2" spacers    and the slightly different position to the rear of the core.   I'll still have a safe .4375" clearance between fan motor and engine belts..........

[emsvitil [OP]]

The thickness of the side plate:  front mounting surface to fan shroud mounting surface (outside to outside) 2 15/16"

The distance from the core to the fan shroud mounting surface (inside to inside) 1/2"

Thickness of core  (header tanks don't matter) As I mentioned above 1 7/8"

What exact part number is this?   As it looks like it's doable.....


thanks

I don't know if this is of much help, but I've got some side-by-side comparisons of a 2-core vs. 3-core here:

Not sure. I got mine about 8-10 years ago from a local radiator shop. Went through all my receipts to see if it was on there, but it just says 3 core rad. I believe that there are three different sizes, but not completely sure on that. Could try calling Radiator Barn and see if they could help you out by giving them the dimension. I've heard that they are really helpful.

scroll down to cooling system  and click on radiator. I like the silla 3 row aluminum radiator.

Thanks, that gives me something to check out


Although I can't stand the aluminum/plastic radiators...................

(can't fix the minor problems you eventually get with solder)

[CrazyYota]

I was talking about the one that's all aluminum.

[emsvitil [OP]]

I was talking about the one that's all aluminum.

Can't solder ALL aluminum either.............

 


I've had  3 solder repairs............

All up top  (part of top seam, filler neck, overflow tube).   All were very minor seepages...

All I had to do was lower the water level and put wet towels around everything.....

Radiator was at least 5 years old before any repairs...

It's easier to just fix a minor problem than having to R&R a radiator (even if you have a lifetime warranty)

Learn something new everyday. I did not know that

if your looking for better cooling on a 22r i used a v6 radiator out of a 4runner on my 22r and i had to drill 2 holes and i used a clamp to hold the bottom of the radiator in so it wont vibrate around and break anything it works amazing and all my hoses off my 22r worked with the new setup
