Larrie Posted August 27, 2004 Report Share Posted August 27, 2004 Hi guys I just inherited a 98 STS with 8000 miles on the odo. First question: The coolant is original and tho low milage is over 5 years old. Should I flush and replace and if so use a chemical flush or plain water? #2 The AC blower has a deep rumble. Is it motor bearings or should I check for an unbalanced cage. Can this be checked from the interior or the engine compartment. I've checked the firewall and didnt see a familiar blower hump.
