Had to replace both cooling fans on my 2007 vw wolfsburg Jetta. Check engine light was on cand causing the engine to overheat. Causing the pressure relief lid on the overflow bottle to be activated causing coolant to come out. This would happen when the outside tem was 50+ degrees fahrenheit. Vehicle would be driving or idle.
