Trial the Engine in a Hyundai
The engine in your Hyundai is built to extreme in excess of 100,000 miles. While Hyundai engines are built to be economical, they are not "perpetuation unpaid." Over duration, you may bound into problems with your Hyundai engine. Some of the enhanced typical problems are valve spring prostration, leaking purpose gaskets, and, on high-mileage Hyundais, a popular loss of compression as the engine ages. Happily, you can easily research for the most commonplace problems in your garage Homewards or in your driveway. Checking a Hyundai engine, if a traditional gasoline powered engine or the newer diesel engines, is resembling provided you bound the diagnostic tests using a vacuum impulse gauge.
Instructions
1. Unfastened the hood and remove the rubber stopper plug in the intake manifold using a couple of pliers. The intake manifold is in the bottom of the engine near the firewall. You'll obligation to pull hardened on the rubber stopper to remove the plug.
2. Push the hose and plug on the vacuum strength gauge into the access gap on the intake.
3. Check for dark black or gray smoke. This indicates that your engine is burning too much fuel and not getting enough oxygen (also called "running rich"). If you Hyundai vehicle is "running rich," however, you will likely see your check engine light come on.
The vacuum strength gauge Testament direct you many imaginable problems with your vehicle. Your Hyundai's vacuum coercion should control stable at sluggish at 22 PSI (pounds per square inch) on the vacuum gauge. Whether it fluctuates wildly from 22 PSI to 10 PSI, then there is a vacuum leak that is caused by effete valve springs that demand to be replaced. Provided the vigour gauge holds regular at 3 to 4 PSI, there is a above vacuum leak that needs to be constant by a experienced mechanic. Whether the gauge reads 10 PSI, then your Hyundai most possible needs a valve timing adaption. Your Hyundai may as well eventuate to misfire owing to it is not getting the Correct extent of air for the fuel that is activity pushed into the engine. Whether the gauge reading starts outside general and then drops to roughly 10 PSI, this indicates a blown or severely leaking intellect gasket which needs to be replaced. You may besides note bloodless steam ultimate absent of your tailpipe while the engine is running however whether it is a baby gasket leak, you may not see this. Your engine may also overheat from a blown head gasket due to the fact that the engine coolant is leaking into the combustion chambers and being turned into steam and is not cooling the engine. If the needle on the pressure gauge fluctuates 4 PSI to 6 PSI away the baseline of 22 PSI, then your Hyundai's valve guides are worn and need to be serviced by a professional mechanic.
5. Check the engine to see if it is shaking. This could be caused by a loose motor mount on either side of the engine which will have to be serviced by a professional mechanic.
6. Check for colored smoke coming out of the tailpipe of your Hyundai. Bluish smoke indicates an oil leak in your engine. White smoke is actually steam caused by a leaking head gasket (mentioned in step 4). Engender your Hyundai's engine.4. Research the vacuum pressure gauge. A rich fuel mixture is usually the result of a faulty O2 sensor or a faulty mass airflow sensor, both of which will need to be replaced by a professional mechanic.
7. Check to see if the check engine light comes on. While this can indicate a multitude of problems, some of them are related to the engine. You can take your Hyundai to any auto parts store, and they can run a free diagnostic test for you using a special tool that will plug into your Hyundai's on-board diagnostic computer. Then, they will give you a print out that will show you what the problem is.
