Thanks to all who responded to my question re: adding an oil cooler to my
AAZ turbodiesel conversion.
DM&FS suggested mounting the cooler below oil sump level to prevent
drainback. Since the lines start from an adaptor above the oil filter
mount, I don't think drainback will be an issue
Ralph M, I think we're dealing with the same issue: a 1.9 L engine in a
cooling system designed for a 1.5. I started out thinking I'd add water
cooling capacity, but there's not much space up front and the cooling
system is already a little sketchy with long hose runs, etc. I think oil
cooling may do the trick. You don't need to change sensors to "match" your
new 185F thermostat. But I don't think the thermostat is going to solve
your problem either.
I'm gonna try to keep it simple, use a thermostatic adaptor plate and a
cooler sized close to the opening of the vent into the engine compartment.
If I need to add a fan (relays, sensors, etc) I can do it later.
One dumb question: On oil changes, do the hoses and oil cooler drain out
the oil filter housing when the oil filter is removed? could be messy.
The List is a rich resource. Thanks, all. David
