Replacing Time-belt is the major part of the car maintenance after every 60,000 to 100,000 miles. And it’s repair bill can cost you more than you thought. The repair goes upto about $450 to $1,000 typically along with other recommended services—it is very tempting, though, to try it yourself. But Avoid. You can potentially damage your engine enormously. If you cause some another fault in the car, it can cost you extremely high.
Battery Change
It is though very inspiring to change the car battery yourself but if you have a little knowledge about it, DIY is off the table. Replacing a battery yourself saves an average of nearly $ 60. This is again very tempting, but even the more skilled street mechanic requires an extensive troubleshooting for diagnosing any related issue. So, it is better left to the professionals. Or, you never know, when your battery ditch you and make you bankrupt for repairing it again.
Overheating issues
A skilled home mechanic with some level of training and right tools can repair a cooling system– like replacing hoses, and the thermostat ( some of the more advanced repairs). But if your engine is already overheated, skip the thought of doing it yourself. There is too much risk involved (your engine and your beautiful face can change shape).
Driving issues and error codes
When your car doesn’t start or you have other drivability issues, accompanied by ‘check engine’ lights, you just cannot have enough ability to do it yourself or diagnose the issue. Commonly, people try to get under the hood themselves and create some new problems in the process.
This kind of issue serves as a lottery for the shade-tree mechanics, as they are not actually experienced to troubleshoot the problem. Most of you commit mistake of trusting them and their half held service start up to add more money.
Repairing Transmission
This is no manual transmission. Repairing automatic transmission can be overwhelming because it contain thousands of small parts, precise tolerances and narrow passage to hydraulic fluid. Transmission repairs must be left on professional and qualified mechanics than doing it yourself. Maintenance like flushes and fluid change must be made done by the skilled mechanics and not from any random workshop or oil-change place. Because, they do not do the cleaning very efficiently like any car service shop. This can leave girth or residue around connectors or gaskets, which can spoil your household budget in future. Even a grain of sand can wipe out your transmission.
Suspension components replacement
It seems very easy to replace suspension pieces like struts, arms, and bushings. Immature mechanics cant make many blunders while doing this. For instance, a beginner does not understand the amount of force a compressed coil spring holds while replacing the struts. You may not do it correctly and in result can harm yourself and your engine as well. The suspension supports the front subframe and the engine and is quite complicated. A home mechanic cannot practically just do it—lack of proper equipments is one reason. All this can doom your budget lately.
Now, you understand why it is not very cost-effective and safe to repair some car issues on your own. Do it yourself is a little prohibited here.
