SOURCE: cooling fans will not operate
IF YOU HAVE A SCANNER, WATCH THE COOLANT TEMP. LET THE ENGINE RUN UNTIL THE FANS COME ON. IF THEY DO. THE SYSTEM IS DESIGNED TO COME ON AT AROUND 228 DEGREES.

Hi there, have you checked the colour of the oil in the motor, if not clear or normal and have a milky look, it sounds like the head gasket is on the way, it will still drive but the symptoms sound like the head gasket, Check the oil. Hope this will be of some help to solve the problem

First thing to do is replace you fuel filter, If there is a check engine light have the code read, Most parts store will do this for free. Get the code number type that into google for further advise.
