As an aside, there is one mod that all MDX/Pilot/Ridgeline owners should be doing. As the rad ages, the barrier between the engine coolant and the trans fluid can fail, causing the transmission to be flooded with engine coolant, destroying the transmission.
A simple and cheap fix is to install an aftermarket trans cooler. The OE cooler is then capped off, and if/when the OE rad goes south, the trans is isolated from the rad.
My poor Ridgeline owning neighbour found this out after his rad broke.
