Hello,

Yes the heater control valve is located down low in the front and the passengers side. You we need to drain the coolant first.

Here is a guide on that.

You can do the job using a hose clamp tool.

Here are some diagrams (below) of the how to do the job.

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken
