My check engine light came on i brought a new battery it went off i had mycar checked the mechanic said ineed a 02 sensor to keep from burning a lot of gas i also have a antifreeze leak but my car does...
When you removed the old battery and installed the new one, you effectively reset your Check Engine Light-until the fault (I assume it was a fault for the O2 sensor) reset. A new O2 sensor, installed should run you somewhere in the neighborhood of $70 to $125 depending on how difficult it is to get to, what brand is purchased-there are wide variations and some places will use 'universal' O2's to cut costs.with mixed results. A new O2 sensor will react more quickly to engine demands and conditions, allowing the car's computer to adjust parameters more rapidly and efficently translating into better fuel mileage. The antifreeze leak is hard to predict since you did'nt say where it was coming from-if it is a radiator or water pump, in the low hundreds. If it is a heater core, in the mid-high hundreds, maybe worse, they can be a bear especially on fords. A hose is usually easier and less costly. The big thing about coolant leaks is they can get much worse, and dramatically too. Y ou don't ever want it to overheat an engine that is aluminum-if it does overheat it probably will never be the same. Pay careful attention to the temp gague until you can correct this, it is much more important to fix this first.
