I am curious about this I4 conversion. How long have you had it
installed, and has it ever cooled correctly at idle for extended
periods of time?

I haven't done the research, but with this conversion, aren't you
messing with the engine's ability to be cooled down by switching out
which vehicle the motor was intended on being installed in without
taking all the same engineered parts over to the new vehicle..

I know it isn't rocket science, but then again, I understand that
certain setups were designed to cool in a specific way, maintain a
certain pressure, have T-stat open and close at certain
intervals...blah blah blah...

I thought that on the air cools, specifically (although certainly not
same comparison) the air shroud is a very important part of the
cooling system as its intended to direct airflow in a certain way
according to the design of the engine...Could the I4 have been
designed to not be in a rearward "cavern" of sorts and able to shed
less heat than if it were under the hood in front of a vehicle? Is
that enough venilation??

I know on my P30 chassis motorhome, they have had all sorts of trouble
cooling down engines based on the fact that they don't have enough
airflow guided to the right place...it shoots all over the motor, but
doesn't get directed correctly to the radiator, etc...

Just some thoughts....maybe some sort of air dams, or additional fans
in the rearward vents to SUCK cool air into the engine
compartment...Or maybe the radiator needs more frontal space? I
dunno...
