So all this talk of water pumps has me thinking, been trying to problem solve an issue with our FG Falcon. Heater is not working, no heat, so did the usual FG problem, heater control rod, HIM unit and changed the thermostat, which have not fixed the issue. So tinkering around in the engine bay, drop the fan belt to check the water pump for any slop, grinding noise, etc but nothing, when I changed the thermostat I changed the coolant and gave it a flush, surprisingly not that dirty when flushing it. I also checked for error codes and nothing there either.
This morning I started it up and let it run for few minutes now the engine side of the radiator hoses are hot and as I slide my hand down the hose its getting colder, once I get to the radiator its stone cold, top and bottom are the same. The temp gauge is reading fine, it does go up a little when stuck in slow moving peak hour traffic but that's it.
I need to replace the idler pulley and fan belt, may look at doing the tensioner as well
Now before I go pulling off the water pump and replacing it, is there anything I am over looking?
