Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnostic Aids
If an overheating condition is suspected, verify if it is due to an actualboilover. If gauge or light indicates an overheat condition and boilover is not evident, inspect gauge circuit for malfunction.
If vehicle is overheating and gauge or light indicates so but cooling fan is not coming on, check coolant sensor temperature using a "Scan" tester. Sensor may have shifted out of calibration and should be replaced. If engine is overheating and cooling fan is on, check cooling system.
