Antifreeze OEM Toyota or OEM Honda

I did this a few weeks ago on my '13 Sequoia, but I did not flush it. Just drained the rad and the valves on the block. Replaced with Toyota red and distilled water at 50/50. The fluid I drained was as clear as the fluid I replaced, so I felt flushing was not necessary.

I'd recommend genuine Honda coolant. Others tend to cause water pump to leak.

Toyota brand coolant is top notch, supposedly can last for the entire life of a car and never needs to be replaced
