Apparently the heater hose on driver side I leaking.
looking for instructions how to reach clamp and or gain access to the hoses. To replace.
there are no manuals. I purchases the emanualonline but it sucks. Seems like it should be simple. Sorry for my ignorance.

 

I assume it leaking coolant into the interior? Not sure about the 07s per se, but usually the problems on the older Volvos are either the heater core is bad or the o rings between the heater core and the hose need to be replaced. To access you need to disassemble the center console and you should be able to see the bottom of the heater core from there. Did you try going onto Youtube to search for vids on a Volvo V70 heater core replacement tutorial?

 

My bad, it's the Coolant hose on driver side that goes into top of motor. I'm not sure if it the Mass air flow sensor, a large box that is blocking access to the hose. Maybe I should take to mechanic.
