Alvaro, you said in your blog you fabed up some brackets for the mounting. This is probably the best way but what did you think of just mounting it to the rad with those 'cooler mounting kits'? The ones with the foam strips and the zip tie sort of thingy. Be much easier but maybe the bouncing would be bad for the setup.
:cool:
 
I agree Alvaro

Does anyone know what the effect on the engine's cooling system will be when blocking it with a smaller cooler such as the PS cooler? Perhaps you want at least a 1/4" gap or more between the two radiators to allow inter-air flow.

This is a legit concern. Toyota, however blocks half of the radiator with the AT cooler, so they cannot be that worried. My guess is that an engine driven fan pulls so much air, it does not matter that much. Another reason to run a real temp gauge.
 
nice job guys, another "must have" mod on the long list! Does the list ever get shorter? haha
 
Last summer mine started to leak from the tubing that is located under the radiator. My local mechanic quoted some out of the world price to replace with oe parts.

With some searching here on mud we came up with the idea like yours to solve the problem. If I recall the cooler and hoses were $50 plus $100 labor.

My understanding this is quite common in the northern areas because of all the lovely salt used in the winter.
 
Here are some pics from today:

The coil to distributor wire had to come off, the oil filter had to come off, the battery and the battery tray.

At one point we had to drive over to Andy's house and use his impact tools. The nut on the pump's gear and the gear itself were hard to remove using regular tools. We ended up using air tools

Getting the factory cooler was hard too. BTW, I have a perfectly good factory cooler for sale if anybody is interested.

I took the rig out for a spin, no leaks, the cooler is cool to the touch after 10 minutes of driving.

I will write more later once I get back from dinner.

Nice work. Is that you supervising? :D

Was it pretty easy popping the pump off the block?

great pic of the reservoir and fuel filter.
 
IB,

The pump came right off. That was not an issue.
THe hardest part is getting to the pump (battery tray removal) and getting the factory cooler off.

Actually, Alvaro did all the hard work. I just provided moral support and air tools where needed. This job is not as hard as I thought. The key, is making room to work. Having the battery and tray out of the way is good, and removing the oil filter is essential, especially if you use the big -41010 Toyota filters. We also replaced the high pressure hose-pulling that and the return line from the steering gear also made more room available.

One correction-the nuts holding the pump on the block are 14mm if memory serves.

Interesting that Toyota has updated the sealing washers at the banjo bolt on the pump. The old ones we removed were copper washers, the updated one is aluminum, with the two washers joined by a bridge-good design, and impossible to loose the lower washer during re-assembly.

Now getting the old steering cooler out without damage is a major challenge! It would be easy though, with the radiator out.

Anyway, Alvaro's truck drives nice, the steering is great, and we only spilled about 3L of ATF, most of it on my head.:rolleyes:

Hi Alvaro:

I have, for the last 2 years (awaiting a free moment) a small transmission cooler which I planned to install for the same purpose. But my idea was to hook it in series with the stock cooler, between it's out and pump reservoir in.

Would be this setup less complicated and faster to do and with less parts to remove :eek:

I just tring to convince myself to do the job for once and for all, before is too late :grinpimp: .
 
Rob-That would work, of course, but the real issue we set out to address was the low hanging PS cooler that looks like it should get smashed by a big rock. With the cooler moved where it is now, it is much safer.

Going forward, I am going to bend up new 3/8 hard lines and just use short sections of flex hose to make the connections. I think it is even possible to use factory threaded holes to fit the hard lines to the frame.
 
...man, and I thought I was gonna totally burn you with "I already did this!"
steering cooler.webp
 
And it doubles as SRS.

Nice!

Thanks Andrew, but I forgot to mention that I did a 2" front hitch on mine behind my bullbar and under the winch, which as a bonus protect the stock cooler.

I don't want to overtax my cooling system blocking some air flow to the radiator.

I noticed there is a diferent aproach between the USA spec and our third world version:

USA specs use a smaller core radiator and the transmission cooler is outside and in front of the radiator.

Ours have a deeper core, and transmision cooler is inside the radiator lower tank. Manual has the same radiator but without the lower tank transmission cooler.

I guess Toyota's decision to market this aproach in the USA spec could be based in the very common practice of towing. U-Haul is an example, you always are either moving or towing a boat or a cargo trailer. As I recall 80's Land Cruisers were always very expensive against it's american counterparts and first owners in 1992 didn't care about the low overhanging of the hitch option, no 2" lift, not oversized tires because they were drived the same as the Range Rovers: as luxury 4 wheel drive vehicles for the ranch owner or for the same Volvo minded driver on pack snow roads. A 40's series owner could not be compared with a 80's series owner. But this cruisers were inherited by the owners sons or ended years later in the used market were the new owners started the great mods we see and enjoy now.

Third world country 80's rarely town with the exception of the aussies so we don't overtax our automatic transmission requiring extracooling. They were purchased since day one to be in deep mud, remote deserts etc.

Because we are down the equator line, our all year around temp is quite higher (okay forgive me you Texas and New Mexico people) so we practically live with the air condition on and ours don't have the sunroof but got the console cooler (only on the luxury trim as mine)and in some markets there is even a rear air cond option. That demand a lot from our condenser and cooling system and that's why this rear air cond / console cooler model (not mine unfortunately)came with the electrical push fan.

That's why I don't want to add such a larger power steering cooler as Alvaro did, so there is some compromising situation and I need to choose between either not getting enough cooling inside the vehicle, driving my rear seated passengers nuts or damaging the power steering pump because the oil overheat after increased tire size:mad:

THe truth is, that the SA 80 series have less transmission cooling than the USA ones. In the USA, all the 80s have the tranny cooler in the radiator, PLUS the large external cooler covering half the radiator. This was part of the "tow package" that virtually all USA 80 series came with.

In USA trucks, the radiator I think, is the same as any other. In front of the radiator is the AC condenser, and the external transmission cooler. That is why a working fan clutch is so critical to the operation of the cooling system.

Yep that's what I meaned before, but I was not sure if the USA specs had both transmission coolers, I should know it better because my own service manual is a Toyota USA spec FZJ-93 manual I purchased in the states (but as I recall now it doesn't show the extra cooler):rolleyes: .

My question is how will behave a USA specs against a non-USA specs in a very hot weather because of the large external cooler ?

There is no doubt that the extra cooler should put an aditional load on the clutch since there is more airflow restriction.

Even if neither of them are towing anything, the extra cooler should convey some heat over the condenser and reduce is ability to extract heat from the air condition gas and I guess it will tax the air condition inside the cabin at low RPM even if the clutch is fully engaged.

Robmir,

After experiencing first hand the weather conditions in South America, I gotta say that the heat of the US deserts, specially in the south west is a lot worse than Venezuela.
In Venezuela, most of the heat is under high humidity conditions. In the Arizona, New Mexico, Nevada & California in the summer time temperatures can reach 49°C (120°F). With very, very low humidity (under 10%). Humidity in the air is what ultimately makes a cooling system work. With low humidity, a lot more air needs to go through the system to lower the temperature.

I think that a 80 Series equiped with the tow package would do just fine in South America.

Alvaro
 
Just for kicks I did a search on Outer Limits for the larger PS reservoir and found nothing. I posed the question for the folks in OZ, so we'll see what comes up.
 
nice job guys, another "must have" mod on the long list! Does the list ever get shorter? haha

I know just when I was getting close to the end of the list too.:mad:

This is a must do for me. Very cool Top 5 Mod

By the way that picture is great of Andy in his smock rooting around the front of the the truck with the large turkey baster in reach is funny. LOL

:cheers:
Sam
