Auxiliary Coolant Pump Location ‘05 Super V8

I was wondering if someone could tell me where the auxiliary coolant pump is located on my 2005 Super V8. The heat goes away at low rpm (idle), but returns when driving. I assume the auxiliary is not working.

Thanks,

If its anything like my 1999 X308 its just in front of the firewall on the left side of the engine bay looking towards the car from the front.

This link says it’s under the header tank. Be very careful moving that so not to break the plastic nipple for the small pipe.
