The canister style cooler for my auto trans rusted through (darn Minn. salt). I mounted a 10" X 17" auxillary cooler on the rear of the radiator and ran copper tubing with flared fittings ( I am in the propane business - we like flared fittings). I wanted to mount the cooler in the front of the radiator but the plow frame was in the way. Does anyone have ideas as to if the location behind the radiator will give me enough cooling. I should tap into the line and mount a temp gauge on the dash to measure the fluid temp. They don't sell the original coolers anymore and used ones are expensive on ebay.

 

It would seem to me that you don't get a lot of air thru the radiator unless the fan clutch is engaged. The fan clutch on my 92 only engages when engine temp climbs.

I know Minnesota is (usually) cool, but plowing is going to heat up the transmission oil, isn't it? The cooling flow isn't very good in reverse, I know.

I'm in the process of installing an 11"x11" cooler with thermostat and fan under the bed on the passenger side. The fan will come on when the trans oil hits 180* into the cooler. This will take the place of the cannister cooler that I suspected of leaking and removed.

Right now, I'm stopped until I can find a way to tap in a temp sensor (I want to see what's happening, too).

I believe according to hayden you only get 60% cooling behind the radiator, and thats wheem the fan is running. I run a underbed cooler as was mentioned above, its a far better system.
DBF mines mounted in a tee on the cooler, if your outlets are threaded just install a tee right there, seemed the simplist way.

 

loch, the problem is that the sensor bottoms out in the tee. I have to find a way (some sort of male-to-female converter, I guess) that is the right length to put the sensor in the fluid stream but not bottomed out.

The under bed cooler is the method that DC used on trucks that were shipped with the extra cooler installed. It works well and is a much cooler environment than anywere under the hood or near the engine....
Normally the DC supplied cooler was mounted between the frame rail and the inside fender skirt I think (???)

pb....

 

I have a 93 and I am trying to figure out what canister cooler you are talking about and where is it??

 

Look under the turbo.

 

Bob you are correct , it was mounted in front of the left tire. DBF dont put it in the center put it in one of the ends, it wont bottom out, i used a bigger tee than needed and used reducers,

 

Now *there's* an idea. I'll try that. Tx, DBF

 

There's a cooler for sale on Ebay if you want to replace it.
