Confusion, auto gearbox cooler on a UK car

[BOB B]

I posted a thread on Supra chat a few weeks ago about replacing the standard UK radiator (with built in auto box oil cooler?) with an after market radiator and separate auto box cooler, which I now have. I have taken a few things off the car to start this, I followed the pipe work and the confusion for me is:- I have a line running from the gearbox to one side off the radiator, another line coming out of the other side of the radiator which then runs to one side of another cooler in front of the window washer bottle, out of that cooler and onto the other point on the gearbox.

 

It seems to me that the oil has either two coolers (the rad and the one under the front passenger wing) or is one redundant, also if the UKs have this set up why do I need to fit an after market cooler, can I not run the lines straight from the existing cooler to the gearbox.

 

Any help on this before I start removing the bumper to find a spot to fit my new cooler would be very helpfull.

 

Thanks.

No one got any comments on this?

Im not sure but Some one could have fitted an extra cooler before you got the car

I think this is standard fit for a UK but I can't figger why, I'm trying to avoid removing the bumper if I can help it, bit of a work up with the auto spoiler, just can't understand why UK's are like this and imports are not.

Does sound like you've already got an extra cooler fitted. I'd be inclined to move it though and fit it to the front of the AC rad so it's in direct airflow of the viscous fan to give better cooling.
