Engine Cooling problem
2001 Chevy Malibu 6 cyl Front Wheel Drive Automatic 80k miles
Engine Size: 3.1L Sti V6 'Good ol reliable' lol
Hi everyone! First post on this site and I hope theres some people still on this thing. And im sorry but I am going to rant!
I bought this car 9 months ago and it seemed ok (i didnt know much about mech's at the time) lets just say I had no idea of the car being the ultimate lemon in north american (i flushed out that beautiful dexcool in the dark trying to save my gaskets after reading about it lol)
Anyways about 2 months ago whilist on a two hour long journey my temp gauge died, didnt make a sound. Just stoped, stuck at stone cold. On a hot day.
Engine check light goes on next day whilist making the hours back home and this makes me nervous as I had overheating prblms on the really hot days when stuck in slow traffic and my cooling system would bleed out the surge tank saftey hose.
Ok so I read a haynes manual and it tells me that the 'Coolant temperature sensor' is responsible for the HUD gauge and for the ECM and tells the ECM when to turn on my fans. Big job for a sensor.
I bought a new sensor and just before I change it. ITS WORKING?
But not for long. It dies in a couple days again
So screw it, I got a deep socket and changed the sensor myself (in the canadian tire parking lot lol). Turn the car on and the gauge works for like a second barely making it a quater way up. And drops and dies again. Engine check light still on even after I unplugged negative battery cable for a few mins.
This is funny overheating in summer and now underheating in winter sigh*
So thats my problem
-Temp Gauge no worky
-Bad (meaning worse) gas milage
-Heater works but barely
-Engine fans always on
any ideas people? Help woud be very much appreciated
