Running Problems? Check the Big Three!

If you find yourself unable to start your engine it could be missing one of the three major components needed for an engine to run compression, fuel and spark, without ANY one of these items NOT working the engine will NOT run leaving you calling the tow truck on the side of the road.

#1. Compression - This area of the motor results by crankshaft rotation and pistons moving up and down inside the engine block. Once the pistons reaches the top of the cylinder with fuel and spark inside the compression allows the explosion to occur returning the piston to the bottom of the cylinder wall pushing your vehicle forward. If the timing belt or timing chain fails it will cause the camshaft to become out of correlation with the crankshaft or allow the camshaft to stop rotating correctly. Either of these conditions will cause the engine to lose compression and sometimes cause internal engine damage.

#2. Fuel - Fuel delivery is what feeds your motor and if it doesn't eat it will die! The fuel system is made up of these major component parts: fuel pump, fuel injectors, pressure regulator, fuel filter and fuel pressure lines. This system is used to supply fuel under pressure to the fuel injection system and/or carburetor, the lack of fuel pressure or volume will cause the fuel delivery system to fail and the engine to stall or not start.

#3. Spark - Without spark to ignite the fuel you will not create the explosion inside the cylinder needed to drive you forward. The ignition components include: spark plugs, spark plug wires, distributor (if applicable), crankshaft angle sensor, camshaft angle sensor, ignition coil, ignition module, knock sensor and PCM (powertrain control module). The engine relies on the ignition spark to be delivered to the combustion camber at the correct time. If the ignition spark stops or is delivered at the wrong time the engine will not run or run poorly.

If your vehicle is running poor or not starting make an appointment today.

How Do You Know When You Have a Blown Head Gasket?

A blown head gasket can be very bad news. It’s very expensive to fix and in this article we will provide symptoms so you can keep an eye out on your vehicle. The above picture displays how coolant has made it's way into an engine's cylinders resulting from a blown head gasket.

Overheating

The biggest cause of a blown head gasket is overheating. Before replacing the gasket, it’s vital that you find the cause of the overheating problem. It could be due to coolant leaks in the engine, the hoses, the radiator or the water pump. These have to be found and repaired. It could also be due to the cooling fan not working or the radiator being clogged. Again, these need to be fixed or, you’ll end up with another blown head gasket again shortly after your repair leaving you on the side of the road.

IF YOUR EXHAUST SHOOTS WHITE SMOKE OUT IT COULD BE A BLOWN HEAD GASKET

Installation Error

If you have had a blown head gasket replaced on your vehicle and you solved the problem of why it blew in the first place, the likely cause this time will be installation error. This is not particularly uncommon. When head gaskets are installed the head bolts need to be tightened in the correct sequence and set to the proper torque. They also need to have clean threads and are not stretched or damage during installation. The cylinder head surfaces and engine block also need to be smooth, clean and flat. Any one of these factors can cause a blown head gasket. 

Hot Spots

There are engines that are prone to hot spots between the center cylinders in the cylinder head, although aftermarket head gaskets for these engines are reinforced to lessen the possibility of a blown head gasket.

However, if you have an older car, the hot spot could be the cause especially if your old head gasket has been replaced by the aftermarket one that’s not reinforced.

Pre-ignition Problems

Pre-ignition problems can cause a blown head gasket, especially if you only use your car for city driving. With pre-ignition, there’s a hot spot in the chamber which causes ignition of the fuel before the spark plug has a chance to fire. It could also be due to detonation. This happens if the spark timing is too advanced or the fuel mixture is not rich enough. It causes carbon deposits to build up and ultimately erodes and blows the head gasket.

Bad Head Gasket

In some cases, the original head gasket for the car can just be very badly designed and the poor design can cause a blown head gasket over a period of time. A little research will establish if your vehicle is prone to poor designs, once you replace it t with a good head gasket, you should not experience any further failures.

How Do You Know If Your Thermostat Is Going Bad?

What is a Thermostat?

There are a few ways to tell if a thermostat is going bad. The thermostat keeps your vehicle running at it's proper temperature, so keep an eye on the temperature gauge of your vehicle and if it starts moving up on the hot side and then kicks back down to a normal state, it should be functioning correctly. You want to make sure that your vehicle temperature climbs to a high temperature and then decreases.

If the thermostat does not start decreasing until and it reaches a danger zone, then the thermostat may be faulty and need to be replaced. The reason for this is because at a certain heat (which will vary for each car) the thermostat should open, causing the engine to cool down. However, the thermostat is a safety mechanism and should not allow your vehicle to reach a dangerous level which can cause the engine to overheat and damage the mechanisms of the engine or much more problems can occur.

How do I know if my thermostat is functioning correctly?

One way to test whether your thermostat is functioning properly is to turn your ignition off and wait for the engine to cool down. Once cooled, start the engine and open the hood. There will be two radiator hoses (see image below), as you leave the engine running one hose should stay cool, while the other warms up. The cool radiator hose should only change temperature once the thermostat has opened. If this is not the case then it sounds like you may have a faulty thermostat that needs to be replaced.

How do I know when to replace my thermostat?

A thermostat replacement isn't as big of a deal as you might think, as the price of thermostats are not that expensive to replace compared to many other parts on your engine. It would be a good idea to get it replaced as soon as possible if you realize it is faulty and fails the above test. Remember, a bad thermostat could cause more damage to the vehicle and end up costing you more money in the long-run the longer you leave your temperature of your motor at a dangerously high level.

Make an appointment today with Rick's Complete Automotive (707)887-1641. We will evaluate your cooling system and make sure your motor is running at it's proper temperature level.

Why Do I Need My Headlights Restored?

Headlight Restoration

Polycarbonate plastic is found on most headlight assemblies on all major vehicles. This material even though it is generally durable, this porous material makes it open to environmental defect. Instead of replacing your headlight assembly completely headlight restoration services like the one offered at Rick's Complete Automotive may become an alternative to saving you money!

Vision and safety regulations allow for every vehicle to have the most effective light vision available in today's technology but with a headlight surface not allowing your expensive LED headlights to shine through it's lens by design this may leave you prone to an accident. Not being able to see what's in front of you with bad conditions such as rain, snow, or fog can really mean the factor of keeping you on the road or not. This leaves it up to the responsibility of every vehicle owner to schedule regular appointments with a specialist at Rick's Complete Automotive.

Who said to have to do anything or even replace a hazy headlight? Generally as new headlight assembly can run you anywhere from one-hundred and fifty dollars to two-hundred and fifty dollars, but we can restore your original headlights for twenty-five dollars.  As long as your vehicle's headlights can still be restored, a specialist here at Rick's Complete Automotive Services can do the job and save you money at the same time.

NEVER DRIVE BLIND, ESPECIALLY AT NIGHT.

BAD IGNITION COIL INDICATORS

A bad ignition coil is one of the things outside of the various other engine management items that can cause your vehicle to run poorly. This article will help you know what an ignition coil does, and what signs your should look for before the ignition coil goes bad.

How does an Ignition Coil Function?

Spark plugs within your engine explode the fuel combined with the spark the spark plugs produce in the cylinder area of the engine and propel your car forward. This simple task given by the spark plugs rely on a more complex ignition system to fire them at exactly the right time and with the proper intensity. The ignition coil relays power from the battery and then converts the increased voltage to a high level creating spark in the plugs.

What is an Ignition Coil Design?

• 
  Ignition coils are made up of components. The first part by design is the primary coil, and the second part is called the secondary coil. Battery current runs into the primary coil creating magnetic field. This magnetic field causes a current to transfer onto the secondary coil. By this design the voltage in the secondary coil is much higher than that of the primary coil.

  

  
  

  Indicators Of a Bad Coil

  • 
    When your ignition coil fails this will prevent the engine from turning over and starting or if your car happens to be running at the time of failure you could be on the side of the road calling a tow truck since this component will stop the engine from running entirely. This is due to the fact that no current will reach the spark plugs enough to deliver combustion moving your vehicle forward. In some cases, an ignition coil that is failing will still provide some current to the plugs, but it might not be enough for a full spark, which is needed by the vehicle. The result will be a poor running motor. The battery voltage current must be accurate and consistent within the coil or the car will run rough. In this case we had a customer come in with a coil that exploded and you could see the voltage inside the coil making spark. This video displays a worst case possible yet still allows the vehicle to function.
