Question about 2004 Lincoln LS
Hi as the thermostat has been changed it would rule out that being the fault, but you need to check that when the coolant was filled up that it was done correctly as you can get an air lock and this will cause it to over heat.
when you fill the coolant up you need to make sure any air bleed screws are undone if you have them then when you fill the coolant up you need to make sure its just trickled in to prevent air lock, then when its up to its proper level you need to start the engine and let it get to normal running temp with the coolant filler cap off then when its up to temp put the cap back on then see if it over heats.
if after doing the above it still over heats then you may have one of two problems you could have a faulty water pump or worse case head gasket failure.
make sure the coolant was filled up correctly then i would get a gasses test dont on the coolant this can be done at most garages for a small fee getting this done will tell you if the head gasket has gone or not. if its still over heating its not worth doing any work until you have checked the head gasket as you could throw new parts on just to find out the head gasket has gone.
let me know how you get on or if you need further assistance ok
plz rate this solution as i have a whole page of unrated posts, thanks
