Um this wont work for back flushing the block, unless you dont run tstat. They are designed to open at a set temp.

Now if you mounted it to the heater line on the housing it will work.

It would work fine if you mounted it to the heater core output line. Mounting it to the heater line on the thermostat will accomplish nothing because it is still before the thermostat. Either way, if you run the car long enough, the water will get up to temp regardless of fresh water running through it.

Not back flushing.

The heater line on the t stat housing is before the tstat, this way you can get heat quicker so you dont have wait for it to open.

Sorry I didn't add that little detail.

Remove thermostat and reattach housing.
