So I confirmed that the thermostat was replaced.

Now that the weather is getting cool I haven't had any issues with the car over heating for about 3 weeks.

Also now that it is getting cool I have no heat for the interior of the car.

The two possible causes I have come up with are:

1) A clog causing reduced flow which is more noticeable at high RPMs when the higher flow rate is restricted

2) A mechanical failure of the pump causing reduced flow at higher RPMs

What is the best way to clear or find a clog?
