check engine light is coming on and saying its because of a cooling problem but i cant figure out whats wrong with it can someone help?
My check engine light has recently turned on so I got my code reader and ran the code
and it told me that it was a cooling system problem I have replaced the coolant sensor
and that didn't work and the fans kick on as soon as the temperature of the engine gets
over 190 so I don't think that's the problem. Can someone please help me out? Thank
you for your time
get a NEW battery....undo the connection at the end of the 1/0 battery cable what connects to the ground/chassis...coarse wirebrush this free of paint and corrosion....re-attach assuring 300 Cold Cranking Amp starting ability...this and the one that goes to the motor block....the ECU gets fuzzy because it is seeing variable amperage and variable voltage...we aim to correct this condition by providing Solid Steady Power....incidentally the CEL will be reset once you disconnect the bolt for cleaning....fyi~
I had the same thing happen with my 2002 Jetta. The engine coolant light started flashing but my gauge temp wouldn't rise past the 190 mark so I figured it was my engine coolant sensor and I went out and bought a new one. When I got it installed the light was still flashing so I did some research and found the problem was my sensor in my coolant reservoir. The harness that connects the wire leads to the sensor on the side of the reservoir wasn't fully snapped in.once I clicked er in the light stopped flashing. Hopefully it's the same thing with your car. It could also be that the sensor itself is bad and in that case you will have to get a new coolant reservoir tank
