What if I just got a hydrologic engine fan for a 2001 Lincoln ls and the temperature gage is still going up

Wait for an answer no longer...lol. some of the simplest things first, could be a clogged radiator or faulty thermostat.
Could also be an air pocket in the cooling system, or yes a thermostat that is stuck closed. To troubleshoot the thermostat just take it out and see if it remains at or below operating temp
U could have air in ur cooling and need to bleed or ur accuator is bad in the fan or u have a head gasket gone
It is a sealed air tight system and it can be a pain
