I just finished flushing the coolant system on my old pickup. Years ago a added a 'T' fitting at the firewall on the inlet hose to the heater core which makes flushing the system with a hose very easy.

I just drain the block and rad, turn on the host, set the heater on inside and then run the engine for a few minutes till the water run clear.

I wanted to do something similar on our V70 XC but I didn't see a good spot to put a 'T' in for the heater core. Nor did I see the block or rad drains.

I wonder what the best way is to perform a proper flush on the V70?

In terms of antifreeze, is the common Prestone OK or should I stick with the factory coolant because of the metals inside the engine and cooling system?

Thanks,
