6 Common Auto Repair Questions Answered

Dealing with car problems can be an intimidating situation, but being able to troubleshoot common auto problems can save you serious time and money. From performing routine car maintenance to determining what is leaking under the hood, here are six common auto repair questions answered.

  1. When Should I Replace the Brakes in My Car?

Brakes are one of the most essential parts of your vehicle. Depending on how and where you drive, brake pads will last anywhere between 25,000 and 70,000 miles. Pads wear down faster if you tend to stop suddenly or if you drive in an area that is high in traffic lights. The brake pad material also plays a role in their longevity. If your vehicle is in need of a brake pad change, you might notice a few symptoms. This includes the car pulling to the left or right when braking, a sticky brake pedal, a grinding noise when applying the brakes, or a brake indicator light on the dash.

  • How Often Should I Do Routine Maintenance?

When it comes to routine car maintenance, every vehicle is different. Your vehicle’s manual will tell you when you need to bring it in for routine maintenance. Some services, like oil changes, should be done more frequently than others. Your car might even feature indicator lights on the dash that will help notify you when a particular service is needed. Consult the manual to determine what each indicator light means.

  • When Do I Need New Wiper Blades?

How long your wiper blades last depends largely on the climate. The rubber on the blades degrades quicker in hot areas of the country, making replacement more frequent. If you live in an area that gets a lot of moisture, constantly using the blades will also wear them down faster. If the blades smear water across the windshield then you know it is time for a replacement. It is better to replace the wiper blades as soon as possible to avoid any potential safety concerns.

  • What Type of Fluid Is Leaking?

You should take immediate action if you notice any fluids leaking below your vehicle. You can usually determine the source of the problem by the consistency and color of the fluid. Water on the ground is common in warm weather and is typically a result of condensation build up in the air conditioner. It is usually not an issue. Red fluid signifies a leaky transmission or power-steering, dark brown indicates leaking oil, and yellow liquid can be traced back to the antifreeze or radiator. These leaks should be taken care of as soon as possible to avoid further damage to the engine.

  • When Should I Change the Oil?

The time interval between oil changes depends on the age of the car. Oil in older cars should be swapped out every 3,000 miles. Newer cars, however, can run on the same oil for 15,000 miles before an oil change is needed. Check your vehicle’s manual for when you should change out the oil. If you are going on a long road trip and will be crossing over the recommended threshold, then you should change the oil ahead of time. If not, then there is no need to change the oil before the trip.

  • What Do I Do if My Car Wont Start?

There are few things that ruin a day like a car that doesn’t start in the morning. If your vehicle doesn’t turn on, you should start the process of elimination by checking the battery. Take note if you accidentally left the lights on or if the battery cables and posts are badly corroded. After removing the positive and negative cables, take the battery to your nearest auto parts store. They will usually test it for free. If the battery fails the test, then replace it and you should be back to normal. If the battery is fine, then you might be dealing with a bad alternator or starter.

How to Install a Diesel Cylinder Head

A diesel cylinder head has multiple functions. It serves as the top seal for the engine cylinder. It also contains the cylinder intake and exhaust valves that manage engine breathing. Here’s how you can install the cylinder head.

Step 1 – Get Started

First, clean the cylinder head and the gasket surface of the cylinder block. Also remove any kind of oil or dust particles that can be clogging the threads of the head bolts or the bolt holes with the help of a thread chaser. Use a solvent to remove those old deposits using a plastic or wooden scraper.

Step 2 – Install the Gasket

Check the gasket surface of the cylinder head and the block for any warpage. Place the new gasket on the block and install the head assembly. Make sure that you do not rub or slide the cylinder head across the block, as there are locating pins on the blocks. Ensure that a new gasket is used that has not been compressed previously by using tightening bolts, as a cylinder head gasket gives a strong seal only once. Make sure that the new gasket matches the one it replaces. Now, install the pushrods and the rocker assembly. Then position the crankshaft to the TDC marking.

Step 3 – Tighten the Bolts

Make sure that the cylinder head is placed in proper alignment with the cylinder block. Tighten the cylinder head bolts by following the proper torque sequence. It should be noted that while tightening the bolts an initial torque and a final torque should be applied.

Step 4 – Install the Camshafts

Using a new gasket, install a new intake manifold and tighten the retainers accordingly. Now, place the camshafts on the cylinder head blocks and align the bearing caps over it. Tighten the bearing caps bolt in stages applying torque from center onwards.

Next, with a driving tool, carefully place the new oil seals into position. Install the No. 4 timing cover and the timing pulleys onto the camshaft. Make sure that the matchmakers and pins are in alignment. Rotate the engine till the matchmakers align.

Step 5 – Connect the Wiring

Connect the coolant hoses from the outlet on the front of the cylinder head and from the heater outlet on the left end of the cylinder head. Connect the wires joining the temperature and pressure sending units. Tighten the alternator mounting bolts and install the upper alternator bolts. Install the exhaust manifold. Connect the exhaust bracket from the exhaust pipe and the wire from glow plug bus. Also connect the accelerator cable and fuel injection pipes.

Finally, connect the negative terminal of the battery and the ground strap from the cylinder head or the intake manifold. If you are not sure about the connections, most user manuals come with wiring diagrams. Install the engine undercover.

Step 6 – Do Final Checks

Once again go through the entire setup and recheck if all the components are tightly held. Refill the cooling system and run the engine till it reaches the optimum operating temperature.
