I Just need to know how to bleed coolant for 2000 Lincoln Navigator. The to upper heater hose was removed to replace bad alternator. Does this car require radiator to be bled?

I also need to use 200 characters so I can submit this post for this thread.

Site builders also need to put repair topic for coolant system, fuel system, intake and exhaust and various others if you guys require me to pick a topic because my topic doesn't fit your option other than repair.
Do you
have the same problem?

The 200 character minimum is force you to give enough information and details so we can come up with an answer of value as quickly as possible. In this case, when asking an engine-related question, it sure would be helpful to know which engine you have. Regardless, I assume you didn't find a bleeder screw on the thermostat housing. If you already ran the engine and the heater is working and the engine isn't overheating, you're done. Any air will expel into the reservoir when the coolant warms up and expands.

If there's an air pocket under the thermostat, it won't open, the engine will overheat, and most of the time the heater will blow cold air. Thermostats do not open in response to hot air. They have to be hit with hot liquid. Look for a coolant temperature sensor or switch on or near the thermostat housing. Remove that while adding coolant to the reservoir or radiator. I prefer to do that with the ignition switch off until all sensors are plugged back in. That will avoid setting any diagnostic fault codes and turning on the Check Engine light. Reinstall what you removed when coolant starts to run out. At that point the thermostat will open, and any remaining air will work its way out.

Forgot to mention, those selections you're asked to make are just so it can be grouped with similar ones that are added to other posts as possible related questions. We don't look at those. Those are for your benefit. That's how the "Related Questions" appear up there, right below your question. We're only interested in what you wrote, and any clues or observations you noticed that can help us figure out what's wrong. You get our attention by the first sentence regardless of which categories you picked. We can only see that first sentence, then we click and read the ones we think we can answer, and we follow some that other experts answer when we think we can learn something.

Yea looks like I most of the air out it bleeds it I jus force most of it by its own waterpump wit thermostat open heater and defrost on. I was hoping I didnt have to bleed like it like BMW or Hondas or other cars. Thank go ur help heater blow hot. When I took the hose off to change alternator it was bone dry anyways, I only had a couple of drops of coolant. If it didn't over heat then it's shouldn't over heat the way I bleed it. And it's the 5.4l motor not to hard thermostat and resovoir about even level.

And thx. I was jus reference if they want me to pick a topic it's should be more specific for example if it's engine topic I'm only thinking about machine like heads piston block and motor only. That's all I know the guys that are answering it only read the question line anyways that's cool.

Thx for your answer I was going to take the air intake out to remove the temp sensor but it started rain and seen it bled itself anyways through the resovoir.

Then look for a sensor that can be removed to let the air out.

Gotta run. Library is closing in 2 minutes.
