Another overheater
95 XJ 4.0
The Aux fan will not come on when over temp.
Replaced Coolant Switch (gauge)
Replaced thermostat (180)
Flushed Coolant (looked good)
Replaced clutch fan
Radiator & Pump have about 50K - 70k miles
No leaks ... no coolant in the oil
Started overheating after I flushed the coolant.
Runs good (fresh tune up)
any ideas ?
edit: the aux fan stopped working today but has been overheating for a couple weeks

did you flush it after t-stat replacement? if so could have something stuck in t-stat or could have air bubble in system still from flush?
