Radiators: LC vs Tundra (1 Viewer)

[Thebedouin60]

Working on a side project and need some info i can't find on Toyota's radiators. Both rigs have the same power plant but different part numbers for the radiators.

Toyota LC 200: 16400-50382
Toyota Tundra: 16400-0S010

From what i can see on diagrams, there are slight differences on the brackets that mount to the side.

What i specifically want to know is if the Tundra Rad will bolt up to the LC mounts?

LOL, I looked into the differences concerning this a few years back... a little rusty in the memory, but I'll do my best to recall it. It may fit, but the gains will likely be marginal. The Tundra radiator is slightly narrower across the core but roughly 50mm taller in the core than the LC w/ 5.7 petrol. The Tundra core is single tube with a thickness of 38mm vs about 48mm with 2 core on the LC. After measuring and adding up all the tubes and surface area, both radiators have about the same surface area. I believe the fins per inch were pretty close, if not the same, also. A rough guess, the Tundra might, and take that with a grain of salt, be a little better due having more fresh core surface exposed on the face to fresh air unheated air. Where as the second row of tubes in the LC core uses air that has already gained much heat from the first row of tubes.

Now with all the above stated, Toyota produced a different radiator for the 5.7 Sequoias that were built for the GCC. They had different fins per inch to increase efficiency.

My advice, drop your coolant/water ratio to 40:60 or even lower. Add an oil cooler. I might actually get a kit made if someone pre ordered it.

I would imagine the radiators on 5.7 gcc lc are different than on the US LC 5.7.
