Old thread, I know - looking at adding a cooler to help with the added load from towing. I see all the questions about over-cooling in colder weather and reduced load, and I too wonder about that.
I wonder, why not run the lines from the transmission to the auxiliary cooler first, and then to the water cooled exchanger second ? Wouldn't this mean that engine heat would in effect regulate the CVT fluid temperature in a way, either removing still more heat if the auxiliary cooler could not do enough, or in the case of cold weather, bringing the CVT fluid back up to a normal temperature ? This would seem to me to avoid both the complexity of an oil thermostat, and the hassle of rigging some sort of block, particularly here in the mid-Atlantic shoulder seasons when it could be freezing for a day or two, then 50 to 70 over the next several days.
