LOL- I am no way a expert. There is possible that the pump and thermostat are still working but either the thermostat is sticking or the pump is failing?

For example this is more related to my car. But recently it threw a code , and it turns out the thermostat was not opening at a fast enough rate and threw a code. That's a first for me. And of course like the Spyder it was no easy task. Its was built into the thermostat housing so you have to replace both.

So with Lew' issues it really sounds like a sticky thermostat or pump related. Thats as long as all the ports and things are not clogged.
