I can see the value of that. There is the possibility that the radiator cooler will perforate allowing engine coolant to get into the transmission oil and ruin the automatic transmission. I think that Volvo should prescribe a 5-year interval for changing the engine coolant. The anti-corrosive chemicals in the coolant are not rated to last for more than 5 years.

Only some petrol engined auto's need an extra oil cooler if towing in very hot climates according to Volvo......http://vccs.volvocars.se/Accessories...ent/VCC-423211

Does the manual really prescribe an ATF change every 4 years or 48 kmi? Is this the maintenance schedule for the 6-spd automatic?

That was what was advised if towing.

Interesting suggestion Clan.

Is the rad heat exchanger connected via pipes that can be disconnected?

indeed it is yes , "quick release couplings" the fluid flowing through them is very low pressure , just the oil flowing back to the gearbox sump via the oil cooler .
