Frequently Asked Questions

Q: Why is my starter suddenly making a grinding noise?
A: Several things could produce grinding noises. First check to see if it has come loose. If so, install and replace any shims for proper drive gear to flywheel alignment and re-torque to OE specs. If it is still grinding, remove it for closer inspection, making sure to give the flywheel a detailed look. Replace components as needed.

Q: What is a gear reduction starter?
A: In short, it’s a super torque starter. It has a set of planetart gears that give it a lot of speed and the reduction of those gears gives it a lot of torque, providing the best of both worlds. These starters were previously known as Super Torque for racing applications for use on high compression engines. Today, however, nearly everything has a gear reduction starter on it. These starters are lighter, faster, smaller and use less CCA (cold cranking amps) to get going.

Q: How many amps does it take to start an engine?
A: It takes 500-800 CCA (cold cranking amps) on average. High compression engines will pull even more depending on compression ratios.

Q: Why am I hearing a whine or whizzing sound without the engine cracking?
A: The drive gear is slipping and not engaging the flywheel. Replacement is needed.

Q: Why does my starter keep running after the car starts?
A: It is either the solenoid or the ignition switch. You should consult a mechanic immediately.

Q: My car leaks oil on the starter, will that affect it?
A: Yes. An oil-soaked armature commutator and brushes will wear out much faster and you run the risk of a dead start burning up the field coils.

Q: Why does the battery cable on my starter smoke?
A: Resistance. Either from a weak, loose or corroded cable or a failing worn starter. Replace components as needed.

Q: Why does the starter quit working and turning over on my car when it’s hot?
A: It’s most likely a heat-soaked solenoid. Heat-soaked solenoids have much more internal resistance when hot. Replace if needed and add a heat shield and/or wrap the headers with heat barrier wrap.

Q: When do I need to replace my starter?
A: Replace your starter under any of these conditions. 1)If your engine doesn't crank constantly every time the key is turned. 2) If the engine will not turn over and you hear a loud click. 3) If the starter fails to turn off or grinds the entire drive. In summary, if you have a strong battery and any one of these conditions exist, you should replace your starter.
