While undertaking my LE500 rebuild, I was looking at this radiator upgrade kit. But it can't be used with air con because the condenser is in the way.
However, I don't think it would have been of any benefit anyway.
After getting my car back together, I checked out the cooling system by letting it run in the driveway until the fans kicked-in due to the coolant temperature, and subsequently stopping when the temp had dropped.
Now that I'm driving it on the road, the coolant has never got hot enough to make the fans kick-in anyway.
My car does not even have the extra duct behind the fender that I have seen on other cars.
The only mods that I did were to:
1. Replace the underfloor pipes and the pipes feeding the coolant pump with stainless steel versions.
2. Replaced the little plastic tee piece with a home made stainless one (the plastic one fell apart in my hands).
3. Made sure the two vents back to the expansion tank had a very restricted, but continuous flow back to the expansion tank.
So far, no problems.
