I would like to know what the ';coil pack'; on a 2002 Saturn controls. What sensors does it control?

We had the oil changed and a few days later started having problems with the engine missing out. Took it to the shop and found out that there was oil all over the ';coil pack';. Cost $150.00 to have it cleaned up and we're having other problems (radiator light comes on, still missing out, bad gas milage, etc.). The place that changed the oil will pay to replace the coil pack if we can prove that it's the problem. Help!!!I would like to know what the ';coil pack'; on a 2002 Saturn controls.

The coil Pack is for the ignition. Your spark plug wires are connected to it. If for some reason the oil shorted the coil pack, that would cause a miss in the ignition. Use a DVOM to check the coil pack if you know how. If not, Check each spark plug wire to see if it's firing. If it's not, the coil pack is probably bad. Also check the plugs.


A miss will cause bad gas mileage.


The radiator light has nothing to do with your other problem.


It means that the coolant is low. If it's not low, check to see if the sensor is hooked up. To check the sensor, simply unplug it and see if the light goes out. If it does, the sensor is bad.

The coil or coil pack(s) provide energy to the spark plugs. $150.00 to 'clean'? This sounds like a very excessive clean-up cost, more likley this is replacement cost for the unit. Contamination of the unit with oil could possibly short it out, causing misfires and poor fuel mileage. The packs can be tested at a mechanical shop for optimum electrical output.
Well the coil pack controls the coils anf tells what coil to fire and when. It in itself doesent controll any senser the sensers control the coil pack.


Things like the crank shaft senser tell the coil pack where the piston is and when it should fire the spark plug.


If the place that filled the oil got oil all over the coil pack, it will cause the coil to short out and not fire the plug at the right time.


My advice to you is make them pay for a new coil pack regardless, If thy spilled oil all over it, cleaning it will not help.


It is clear to me that thy got oil all over the pack and now are trying to wiggle out of paying for there mistake.
sounds like the oil is shorting it out the coil pack controls just about every thing when it goes out it will even shut down the fuel pump
