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?

Asked by Jul 12, 2013 at 10:15 PM about the 2004 Volkswagen Jetta GL 1.8T

Question type: Maintenance & Repair

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~
