Dont know if the cooler can be added to a 1.9. Dont be mislead by the
coolers small size. This is a liquid to liquid heat exchange. A comparable
air to liquid exhanger would be about 25 times larger in area.This would
just about match one of those aftermarket auxillery auto transmission
coolers.The kind with the fins and needs air to blow through the coil. One
point to consider is that the rubber gasket can fail when the weather gets
cold any you can get a leak of oil.So whats new.
