Picked up a '90 325iX with 213K miles from the auction. No prior service history. After letting the car idle for about 25min, needle was all the way in the red. Popped the hood and the AUX fan wasnt even moving. I will be doing water pump, timing belt, valve cover, spark plugs and coolant flush to prepare it for the winter DD duties. What should I look at and / or replace to start diagnosing the overheating issue?
UPDATE: I did timing belt, water pump, thermostat and a coolant flush and she runs great! No overheating, no issues at all!
