I have a 2000 town car signature series. Having issues with it overheating. Hard to crank n stay running at first, but after I drive for a few minutes then cut it off, I have no problems recranking. I will throw out some key issues. Any suggestions will be appreciated. (Very much)
-purchased a week ago n had no problems driving it from new orleans louisiana to brookhaven ms. Owner was towing company n said it sat up 5 months.
-ball joint was broke, so had to reset fuel pump switch
-new alternator and serpentine belt, battery, thermostat
-EATC self diagnostics test returns no dtc's
-radiator fan does not kick on in low or high, with or without heater or ac on
-jump wire connected from radiator fan to battery proves fan motor is ok
-checked 4 fuses/relays, locations: 50 amp maxi fuse #3 (high speed cooling fan) & #26 which is low speed cooling fan 30 amp in main fuse box under hood. Both were blown so I replaced them. And 2 big relays in small box in between breather and main box, for low n high speed. Swapped relays around n horn still blowed so relays are ok.
-not showing power with test light to 2 15 amp mini fuses in main fuse box under hood, locations #20 (fuel injectors) & #21 (heated o2 sensors, tranny solenoid, evap canister vent solenoid, egr vacuum regulator, evap vapor management valve). Replaced both with new fuses, test light still wont come on. Is this normal or possibly an electrical issue?
-hoses from radiator n water reservoir have good pressure, so I dont think it is water pump
-have not saw any leaking hoses
-thinking a sensor could be the cause (coolant). But which one and how do I test it?
-any ideas/suggestions? I have both owners manual n repair guide book, but I am female and am not a mechanic. Lol. So please be user friendly. : ))
Btw, check engine light is on, flushed radiator. Still samr problem (overheating)
