Engine will not warm up and no heat. on 2002 Ford Taurus

Replaced thermostat and both sensors, fluid is running into and out of the tank. Does not appear to be air trapped or at least I cant get it out if there is.

Get a better quality thermostat, yours is not working. If you were low on coolant, it wouldn't take very long driving to get hot.

How can I tell If its opening or not. In the Taurus, is the lower supply or return? Eg, which hose should be hotter? Usually I can not hold the top hose when the engine is hot but now it's cool enough to hold but still hot.

The way an engine warms is the thermostat. The thermostat stays closed to not allow the coolant to circulate allowing to stay in the engine block until it heats to the regulated temperature then opens to allow the coolant to circulate until it has to close again to heat the coolant again. It is a constant process of open and close to regulate the temp.

So then even a new Thermostat could be bad. Someone said to look at the fan thermostat. ??????? Nah! LOL!

That was a good answer, for stupid people. Yes the thermostat or any other part now days go bad all the time. The quality of parts now days are crap. The more expensive lines are supposed to be better quality, and do work and last longer then the cheaper line. I've replaced thermostats, brand new with a cheaper line, because the customer didn't want to pay the higher price for a better quality one. After replacing it twice because the heater didn't work as well as it should have, he then decided to pay for the better one, made some decent money on that one, but he learned what I was talking about at his expence.

Thanks Professor G. Changed the thermostat to a top line, flushed and burped and now I can blow dry my hair on the way to church. You are a life saver. Thanks from myself, my wife and my 2 year old. God Bless.
