Why isn’t there a driver side radiator vent?

[Kujiwara]

All 3.0L Autos have trans cooler in front and both Aux coolers on the sides. North American Manual Transmission 3.0L's also have both aux coolers. Not sure what other countries have.



No, the North American 3.0L B58 manuals have both aux coolers.




Must be an aussie thing because we have them on MT models here in North America:

Just found some photos of the 3.0L Manual in Australia. It does indeed have it's left side blocked. Sucks for you guys!

I wonder if there's a differences in cooling between GT and GTS models, they seem to get the 285kw(382hp) motors like NA so it's pretty weird they don't have the aux rad considering how hot it can get there.

I have two aux coolers in my EU spec 2025 3.0MT (340ps).

It’s indeed strange the Australian spec don’t get it considering they have the 6 port 382hp version with the higher state of tune.

Have the 2026 Track Edition Manual (Australia) (known as Final Edition in USA).
No LHS Auxiliary Radiator fitted.

My primary purpose for this car is competitive track days.
While I avoid Summer track days it can still be quite hot in early Spring and Late Autumn.
Sounds like I am going to have heat soak issues considering this Aux Radiator is meant for the turbo side coolant circuit from my understanding.

Now the question.
Has anyone ever retro fitted all the parts to a Supra that does not have the LHS Aux Radiator?
The diagram already posted is a good start.
But I gather there is going to be gotchas as there are probably other parts differences in what is on my car that won't allow fitment of all the below.

I haven't done it but I costed it out a year or so ago and it's not that expensive to do. I think the parts came to 600USD or there abouts and it's in the main cooling system circuit. The only issue would be if the front support frame has the mounts fitted the rest looks easily doable.

Have you got the full list of parts?
Wouldn't mind having it.

I am actually heading out to One Raceway tomorrow for the cars 2nd track event.
It is only going to be a top of 23C so not exactly going to test any cooling out.
Main aim is to sort the handling for next year's NSW SuperSprint season. I

Both the left and right aux radiators are for the main engine coolant circuit from what I know.

it’s still a good thing to add if you’re gonna be pushing the car hard I reckon.

This might actually be a good opportunity to directly install the Verus oil cooler, which has a lot of data from the time attack community. The tricky part here is that you might be missing some bracket/duct hardware, however.

I agree. If the OP is gonna be doing more frequent track events, it would be a great opportunity to install the Verus oil cooler which is likely something that you would eventually need when you go into the warmer months.
