My daughter recently purchased a 2010 FFH. Great car and a great deal ($3,650 with 150,000 miles and some cosmetic paint damage). I am an avid shade tree mechanic and enjoy learning about different vehicles. I'm in the process of performing the 150K mile maintenance and am having trouble finding out how to drain and replace the hybrid system coolant. I've purchased the AllDataDIY subscription for this vehicle but it does not go into details on how to perform this maintenance action. Is it as simple as draining the hybrid drive radiator and poring in the new coolant into the hybrid drive coolant reservoir? Thanks! Bruce
