Transmission tunnel water pipe orientation

[Nick]

Hi,

What is the general consensus as to which should go on top, the hot or coldish one. Is this correct.

Heat rises so I would put the hot on top to minimize heat transfer to the cooled pipe.

Also it makes the physical installation simpler if you have the hot pipe on top and the cold pipe on the bottom as you don't have to cross over each pipe.

The hot coolant exiting the motor is usually up near the heads and the cold entering the motor is at the lower half.

Makes the plumbing much easier.

Thanks that's the way I saw it.
