Engine overheating

Can a bad aux water pump on 02 ls v8 cause overheating? Changed thermostat and it quit overheating for about 90 miles. Car began to overheat again. Heater also doesn't work. Cant get steady stream from bleed hose by degas when I try. Already have electric fan bypass installed

Inhad the car for about 7 months woth the heater not working before having any over heating issues. Woukd that matter? Will follow link now

Bottom of oil cap has residue like described in link

It is overheating. I have replaced the thermostat and it fixed the problem for about ninety miles and then overheated again. There is no coolant in my oil or oil in my coolant. I have tried to bleed the system, but I cannot get anything to come out of the bleed hose by the degas bottle. None of the hoses leak that I can tell. It "boils" over in my degas bottle. I have been reading that those degas bottles can fail quite often. So that was where my next stop was going to be. However, today I was told it was likely the auxiliary water pump. When Googling it mentioned heater not working. Which my heater has not worked since I purchased it used. Would this cause overheating? About to just sell this car if I cannot figure it out quickly. Thank you.

I was just driving on the interstate, then like four hours into the trip the car started to overheat. So I turned the heater on in the vehicle and the temperature went down. However, I ran into traffic then it took a dump on me. The status indicator advised pulling over and shut off ignition. I did so and let it cool off turned it back on and checked oil level, and coolant levels, both were fine. There were no leaks, so I turned the car on after cooling and checked the engine compartment turns out the radiator fan stopped working. Please help me out.

I thought the Lincoln IS v-8 does not have a relay for the radiator fan. Although I am not sure. Is this an easy fix?

I am almost positive that driving at highway speed will force enough cool air into the radiator to make the vehicle drivable on the highway. I mean is there anything I can do mechanically speaking to at least get a temporary fix until the morning?

Thank you very much for the information, you were very helpful.

Hello team, please check this over heating issue.I never pass a similar experience like this.

Basically the car LS 2003 V8 had an issue with the thermostat. This was necessary be changed after 50 miles of drive the car. In the last 4 miles the temperature increased in a short period time to the high limit. With the protective system the car was turn off. One time with the mechanical service the follow items was changed: thermostat, radiator, coolant temperature sensor, water pump, plastic joint parts (housings), head seals, coolant and the 2 caps (radiator & coolant tank), this last was damaged by the pressure during the over heating.

After all parts changed I still continue having in the car the high temperature in 8-10 minutes of continue engine operation, after this period time the car turn off automatically by the safety system.

I need information about the coolant flow in the system, the pump pulley rotation, the belt installation, the manner and values to test the old temperature sensor, auxiliary pump and the current CTS (cylinder temperature sensor).

Notes: the fan motor is working good, none coolant leak is present, and I already test without thermostat (none change in the result).

I'll appreciate your help and comments.

Since your there all night, let me explain the situation right now. I drove six hours from Williamsport, PA to Waterbury, CT. I attempted to drive on the freeway because I assumed that with it being thirty degrees outside that the cold air would cool some of the engine heat down. Turns out I made it not even two miles up the interstate and it over heated again. I managed to make it back to the place I was at earlier in a safer area than the ghetto I was in and now I am waiting for the shop next door to open up. I am terrified that I will not be able to make it home i.E. I am totally freaking out right now. I am not that mechanically familiar with the Lincoln so I am pretty much helpless. I do not know what I should do. Just venting I guess, wish I could know what is going on with my car.
