Automobile Repair

Saab manufactures cars that owners have come to trust. Even a trustworthy autos require occasional maintenance or repair, however. If you’re in need of Saab Auto repair from experienced professionals, your local Auto Helper can help.

The vehicle is not starting   
If your vehicle either takes a long effort to start, or the vehicle just won't start by any means then the most predictable issue can be a dead battery. You need to be very observant in order to correctly identify and troubleshoot such an issue with your vehicle. If In response of turning your ignition key the vehicle is totally silent than the issue is with the battery or connecting terminals for sure. If there is a cranking sound while ignition than the issue might be with the fuel intake or the spark plug. In any case, you can arrange a tow truck or if possible can jump start your vehicle using a jump starter kit to safely reach a nearby workshop for further investigation of the issue.   

A Sputtering Engine   
If your engine is sputtering, this can be caused by a multitude of factors too. A torn fuel line, bad quality gas, dirt in your gas tank, a leaky injector, a faulty coil pack, worn fuel pumps, and even something as simple as fouled spark plugs can all be the cause of you getting stuck on the side of the road. Hence, we recommend inspection of these areas as soon as the issue begins to present itself, working your way from the cheapest item to the most expensive or most difficult to repair. Hoping that it will go away can result in greater problems down the line, many of which can be very costly.   

Heavy Oil Consumption   
It is not uncommon for an engine to consume oil - this is a byproduct of heat and wear. However, if you find that your vehicle seems to be using more than normal (a quart every 1,000 miles or so is regular), then it may be a good idea to inspect your vehicle for leaks or other problems. Worn gaskets can contribute to a leak, as can an aging sump plug or a damaged oil filler cap, but if none of these appear to be the cause, then you may have internal issues. One possibility is blowby on the piston rings. A compression test can confirm if this is the problem.   

Battery  
The battery is one of the principal components of a vehicle that its needs in order to work appropriately. The life expectancy of a battery is around 5 years. The battery comprises of lead and highly corrosive acid. A normal problem that occurs with battery is bad terminals.  By applying lubricants on the terminals of battery you can keep the battery fit as a fiddle. In case you are not a big fan of maintaining a battery, what you can do is buy maintenance free battery, which will work for a very long period without any issues. However, you can do the following to ensure the proper functioning of your battery: 
1. Inspect battery terminal 
2. Inspecting the connecting wires of the battery 
3. Check the water level, if needed add distilled water. Be careful! 
4. Using the voltmeter check the battery voltage for the output of 12 volts  

Exhaust Smoke  
Unusual smoke from your car’s tailpipe isn’t good news and different colors of smoke depict a different story. 
• White or Grey Smoke: White smoke indicates that the coolant is being combusted along with the fuel and there is a leakage somewhere in the Engine block, cylinder head, and head gasket. 
• Blue Smoke: Blue smoke indicates that there is a leakage in the valve seals or guides or the piston rings have worn out, which are causing the engine oil to penetrate into the combustion chamber which is causing the oil to burn along with the fuel. Hence Causing Blue Smoke. 
• Black Smoke: This means that excessive fuel is being burnt in the combustion chambers due to a leak in the fuel injector, a stuck fuel pressure regulator, or a restriction in the fuel combustion pipe. 
This usually happens with relatively older cars and in such situations, it is very crucial to get the leaks checked by a specialized mechanic.  

Low fuel mileage  
Even though aggressive driving is one of the major causes of your car’s low fuel efficiency. However, if your car’s fuel efficiency is taking a hit despite you being a responsible driver then it is about time that you get your car serviced. Delay in car servicing can cause parts like spark plugs, O2 sensors, fuel injectors, and air filters to get dirty and clogged up, and hence they cannot function efficiently for optimum combustion of fuel. Hence, a comprehensive servicing of your car means all such parts are cleaned up or replaced (if necessary) and you can get your car’s fuel efficiency back on track.
