Battery, Charging, and Starting Systems

Often times a dead battery is an indication of another problem. Using “state-of-the-art” electronic equipment we diagnose the most common electrical problems in today’s vehicles. This check ensures that all electrical systems are operating properly, thereby achieving maximum life and dependability.

Electrical Check Includes:

  • A full analysis of your battery’s condition, including its state of charge and ability to hold a charge.
  • An inspection and analysis of the vehicle’s starting and charging system, including the starter, the alternator and the voltage regulator to ensure proper charging to maximize the life of the battery.
  • An inspection and adjustment of the alternator belt if necessary. A loose alternator belt can cause your battery to discharge prematurely.
  • A cleaning of the battery’s connection and cable ends, as well as an application of corrosion protection.
  • Professional battery installation including cleaning the battery tray and cable ends to ensure good, clean connections.

Cooling System Maintenance

Coolant protects your engine from freezing or overheating, but its effectiveness can diminish over time.

A cooling system failure is the number one reason for automotive breakdown on our nation’s highways. Unlike a flat tire, you can’t stop and put on a spare. Trust Mr. Cool to get your vehicle operating at the right temperature. Mr. Cool’s ASE-certified technicians will efficiently have you back on the road with a properly maintained cooling system!

Recommended interval: Every 6,000 miles or every 6 months

  • Your vehicle overheats.
  • Your coolant light comes on.

Computerized Wheel Alignment

An easy way to substantially improve your vehicle’s handling, and extend the life of your tires, is to be aware of signs of misalignment and to have your wheels aligned immediately if signs appear. Wheels become out of alignment due to many factors such as dramatic stops and starts, hitting curbs hard, accidents, heavy loads, potholes, and normal wear and tear as the vehicle gets older.

Mr. Cool’s Complete Auto Care technicians will align your vehicle so that your tires wear properly and the vehicle travels straight while driving. By properly correcting Caster, Camber, Toe and Thrust Angle, it will increase tire life, reduce wear and tear on steering components and improve the handling characteristics of your vehicle.

Alignment Problem Warning Signs:

  • Your steering wheel is not straight when driving on a level road.
  • You hear strange noises in your suspension system.
  • The vehicle wanders from side to side.
  • Your vehicle pulls or drifts to one side when you drive in a straight line or brake.
  • You hear squeals when you turn.
  • You feel vibrations in the steering wheel or through your vehicle’s seat.
  • The vehicle’s steering feels loose, mushy, or too tight.
  • Your tires are wearing prematurely or unevenly.
Engine Tune-Ups

When your car is properly tuned, the ignition system, fuel system, emission system, and the computer system are all working together. This results in peak efficiency and optimum performance. A drive-ability problem is not always solved by a standard tune-up. The problem may be unrelated to a tune-up and may require a comprehensive diagnostic service. Trust Mr. Cool for expert maintenance tune-ups and engine diagnostic services.

Engine Performance Warning Signs

  • You lose power.
  • Your gas mileage drops.
  • Your engine “knocks” when it accelerates.
  • Your engine stalls.
  • Your engine starts hard, even when the battery easily turns the engine over.
  • Your engine continues to run after you turn the ignition off.
  • There is a noxious (harmful) exhaust odor.
  • Your engine runs rough at any or all speeds.
  • Your engine backfires, spits or pops.
  • Your engine dash warning lights stay on.

Mr. Cools Maintenance Engine Tune-Up service includes

  • Installing new spark plugs
  • Set timing (if applicable)
  • Adjust carburetor (if applicable)

Fuel Injection Service

When your car idles rough, hesitates, stalls, or it does not seem to have the power or fuel economy it once had, a Fuel Injection Service may be the answer. Often these symptoms are mistaken as signs that a tune up is needed.

As you drive your car, carbon deposits build up on fuel injectors, engine valves and in the combustion chambers. Deposits also form on the throttle body, and in the intake manifold as well as in the catalytic converter. This accumulation of carbon and sludge can cause a drastic drop in both fuel economy and performance. Fuel additives are largely ineffective because they target only the fuel injectors and are not concentrated enough to clean away stubborn carbon build up. They do nothing to address the other areas that are arguably more important than the fuel injectors.

The only proven way to clean the entire fuel and intake systems, as well as the combustion chambers, engine valves, and catalytic converter is by performing a comprehensive Fuel Injection Service. For this service to be effective, it must be performed by a qualified technician using the proper equipment and solvent solution.

It is recommended that this service be performed every 12 months or 15,000 miles as part of your routine maintenance schedule to keep your car running clean and efficiently, and performing like it did when it was new.

Fuel System Warning Signs

  • Your vehicle is hesitating.
  • Your vehicle is having trouble starting.
  • Your vehicle is achieving poor gas mileage.
  • Your vehicle is operating sluggish with poor performance.
