Yes, on both (due in 2 years).

Port coolant rad is 'cold' side, currently the hose runs from this port rad in
a distinct upward slope (20-30 degrees), then appr. horizontally over the
engine,
then down behind the engine to the coolant pump.
I was thinking to keep this routing and put the heat exchanger at the lower part
of this upward sloping section of the hose (close to the coolant rad). A
mounting
bracket will be required to retain distance between heat exchanger and some
underlying bits and pieces.
By doing so, from the coolant system perspective, only one thing will change: a
short section of rubber hose will be replaced with the metal bore of the heat
exchanger (and of course two added clips). Everything else remains unchanged.

This was exactly what triggered me to pop the question, thanks for clarifying.

(I am trying to understand the physics at work in the section between oil tank
and sucking oil pump, hence following questions - please forgive my ignorance
[Wink] )
(let's assume no leaks anywhere) I would expect siphoning in either direction
can
only be avoided if and when both of the following are true in case engine is
not running:
1. oil pump does not allow air from inside engine to creep back into this
section
nor does it allow oil to flow into the engine
2. oil tank does not allow air to creep into this section either
Can anyone confirm that the oil pump indeed prevents air from creeping back into
the hose and prevent oil from flowing into the engine - is it by any chance
the hydraulic valve tappet that takes care of this?.
If I am misunderstanding this part completely, can anyone please explain what
physics
are at work to close down this end of the section?
Assuming that the oil pump does indeed stop oil and air from flowing in either
direction, I would think that the 'pipe' that sucks oil from the oil tank
prevents
siphoning from that end because it sits well below the oil tank's oil level
(preventing air from entering that section). Is this reasoning correct?
