A4LD cooling

[X-North]

Hi
Anyone ever changed the OEM tranny radiator of an Explorer 1991-1994 ?
What car or truck you took it from and did you put an electric fan on it ?
Thank you

i just put on a summit brand tranny cooler on mine removed the factory cooler .
its a big cooler so i dont need a electric fan on it , also i removed the ac rad as its not working anymore

 

[X-North]

AC system was all removed even the AC rad and the lining and the condenser except the compressor because of the strap

You could remove the AC compressor and put a new belt on that fits a no-AC engine. That's what I did a couple of years ago.

yes i could but mine is almost new and a new one cost 60$ where i am...dont talk me about buying it from usa because i will have to eait the custom...pays shippings fees etc..it would cost even more...but next winter i will do the swap for sure

Does anyone also know what is the flow of the fluid? On the radiator is it the upper or lower fitting that is inlet and outlet ? I have seen that the guy before me put a aftermarket radiator in-line with the oem radiator.

 

[fordnut71]

the explorer comes with a external tranny cooler in the front grill an also the engine rad cooler. the flow goes threw the engine rad cooler then out to the front grill cooler an then back to the transmission.

ok but on the rad wich one is the inlet form the tranny to the engine rad?

According to my notes, the upper line ON THE TRANSMISSION is the return line.

Sooo, just follow the upper line on the transmision to see which spot it goes to on the radiator.

The upper fitting on the radiator is the return line to the transmission.

Thank you man. I was thinking about removing the lining to the engine radiator and putlong hose under the hood ...cut a hole in the hood bolt the small tranny radiator there and put a ram air cover. It will be redeck but why not?

There is plenty of room to mount it in front of the a/c condensor (behind the grill).. I even put a Fan from a Geo Prism on mine (10" fan) and it BARELY fits.. I could put it closer to the a/c condensor to make it fit with more room but it is fitting as it is.

I'm using a permacool plate style cooler as my aux cooler (I have two aux coolers).. I'm using a piece of 3/16" strap metal from the center radiator support (the verticle piece under the hood latch) to a side piece of the radiator support. I can then just bolt the cooler right to it (I only have it mounted at the top of the cooler.. many miles later and it is still fine).

We dont have geo prism here sorry and my a/c rad is already gone with all the AC hoses and system. Can you post picture here because i am not sure to understand what you are talking about.

 

[Maniak]

the Geo Prism fan is also on the Chevy Prism and the Toyota Corolla (I'm not 100% sure on the Corolla model but I know its a Toyota).

Here is a pic of one of my early cooler setups.. You can see the black cooler behind the fan. I have a piece of 3/16th steel from the verticle steel piece in the center to the metal on the right (you can't see that piece).

Since then I replaced the cooler you can see on the left with a plate style and I mounted it like I did the cooler you see on the right.

Since you live in a cold climate, you should not bypass the cooler which is part of the radiator. It will warm the fluid up to the correct operating temperature, then the external cooler will maintain a cool temperature. JC Whitney sells the heavy duty stacked plate coolers. # 52 in my list of useful threads has a cooler line identification chart for many different types of transmissions: http://transmichigan.com/html/cooler_line_id.html

Unfortunately not all auto equipped Explorers came with aux tranny cooler. both my explorers 95 &96 didn't come with any. I wound up adding one off a Hyundi on my 95. I still need to hook in my tranny temp gauge.

I will stay with the idea of a ram air cooling system. Cheaper and also easier to do. Thank yuo for the link i will do that this summer maybe putting a third cooling rad

 

[X-North]

It was an error to say that the upper radiator line is the return ...its the first line that take the oil from transmission and go to the rad the lower go inside the aux cooler and then go back to the tranny
