How to install an XC90 power steering cooler into an ‘02 Volvo V70 XC. This is a bit of an overkill unless you plan on doing some towing but given how many issues are out there with these racks i gave this a shot for kicks. Works great. Plan on topping up with at least 1/2 to 2/3 of a quart/litre of ps fluid when done. Also plan on a lengthy burping (first with engine off and wheels of ground and then with engine on).
