Need Truck Service? 5 Warning Signs!

The cold temperatures of winter may have taken a toll on the operating condition of your truck. It's not too early to start thinking about truck service for the spring and summer. Hard starting, no start, blue/white exhaust smoke and rough running are signs that you need the services of a qualified truck repair technician.

If you are looking for Truck Repair Milton-Freewater OR your search can be over now with our wentland Diesel Auto Repair Shop Milton-Freewater OR . Meet our Car Air Conditioner Milton-Freewater OR Mechanic to solve any of your car problems. 

Here are a few warning signs and symptoms to watch out for that will give an indication of the type of truck repair required, such as:

   1. Fluid Leaks. Leaking fluid is usually an indication that hoses have broken, gaskets have lost their seals or fluid containers have cracked or come unattached altogether. Leaks also pollute the environment.

   2. Decreased Fuel Economy. Decreased mileage is usually an indication of poor engine performance. You may simply need a tune up service or a carburetor or fuel line cleaning. If ignored, it could lead to a more expensive truck repair in the future.

   3. Noisy Brakes. Noisy brakes are one of the most obvious warning signs that something is wrong. Screeching noises usually come from brakes that are wearing out. Consider the way your brakes feel when you step on them. They should be easy to push and feel soft. If the brakes feel as if they are grinding, stopping you with a jerk, feel either too mushy, or too hard to push down, don't delay in scheduling a truck service.

   4. Excessive Vibration. A certain amount of vibration is normal in most vehicles. However, if the vibrating is excessive, it can be caused by wheels out of alignment or improper balancing of tires, which can lead to other serious vehicle problems.

   5. Shifting Problems. When you shift gears, they should shift almost instantly. If your shifting is sluggish--taking longer than usual to shift from one gear to the other--it typically indicates a problem with the transmission. Because transmissions are expensive to repair and replace, address any shifting problems without delay to avoid a more serious and costly truck repair.

Auto Repair Shop Offers Driving Advice for Surviving Potholes!


How many potholes do you drive over in your daily commute? Many of them may be small, and some of them may be quite large, all resulting in a very bumpy ride. Drivers need to be extra careful navigating the roads, especially on rainy days and at times close to dawn and dusk. Auto repair shops are busy taking care of urgent auto repair for vehicles suffering from pothole damage.

If you are looking for Car Battery Replacement Milton-Freewater OR your search can be over with our Wentland  Diesel Auto Repair Services Milton-Freewater OR  . Meet us for Engine Repair Milton-Freewater OR to have safe driving. 

Potholes are typically caused when the constant freezing and thawing of water under the pavement weakens the road and causes large cracks, which when combined with the weight of vehicles, eventually turn into potholes. That is why severe winter weather often results in roads full of potholes, and auto centers full of damaged vehicles. 

A reliable auto shop offers pothole-driving tips to help reduce the risk of damage to your vehicle:


  • Leave plenty of room in front of your vehicle so you can avoid potholes without getting into an accident.
  • If you can't avoid a pothole, slow down before you hit it. Braking directly over a pothole can actually cause more damage.
  • If needing to drive over or through a pothole, hold the steering wheel firmly to avoid losing control.
  • Use caution when driving over a puddle of water--it might be a deep pothole in hiding.
  • Take roads you know so you know about where any potholes are located.
  • At night, try to drive on well-lit roads so you can see the surface and see the pothole before you hit it.

Most drivers know that running over a large pothole is bad for tires. But even small potholes can cause serious damage, such as alignment problems or structural damage to the tire itself. Potholes may also cause your tires to blow out if they are underinflated.

However, damage doesn't stop at tires. Did you know that some potholes can have as much impact on your car as a 35 mph car crash? In a blink of the eye, you can experience even more extensive damage when your car hits a pothole–to shock absorbers, suspension system, struts, rims and alignment.

If you notice any of the symptoms below, be sure take your vehicle into your preferred auto shop to have it checked before any damage gets worse:


  • Your car pulls to the left or right, which could indicate an alignment problem.
  • Uneven tire wear, which could indicate an alignment problem.
  • Low tire pressure.
  • Bulges or blisters on the tire sidewalls.
  • Dents in the wheel rims.
  • Loss of control, swaying, excessive bouncing, or bottoming out, which could indicate problems with the steering or suspension.

Is a Car Tune Up Necessary in Today's Vehicles?

Today's vehicles no longer have any of the components left in them that were part of the traditional car tune up. Advanced technology requires meeting emissions standards put in place since at least 1996. So you may be asking if a car tune up is still necessary and if so, what does it look like today?


If you are looking for Tune ups  Milton-Freewater OR your search can be over now with our Wentland Diesel Auto Center Milton-Freewater OR Shop . Find Quality Vehicle Maintenance Milton-Freewater OR  for Long term Vehicle Maintenance.


In older model vehicles, a tune up traditionally consists of the following:


  • Recalibrate the carburetor: The carburetor was responsible for creating an air and fuel mixture which was then pulled into the cylinders.
  • Reset or replace the points: Points were moving parts responsible for timing the spark to ignite the air and fuel mixture.
  • Replace worn out high voltage wires: Wires which ran from the distributer and points to the individual spark plugs.
  • Replace spark plugs: or reset the gap if the spark plugs were not replaced.

Today's tune up involves advanced technology:


  • Carburetors were replaced by fuel injection systems which use electronics to measure the fuel added to the intake.
  • Distributers and points were replaced by electronic ignition systems.
  • High voltage wires have been replaced by coil/plug ignition systems. This means that the high voltage is created at the spark plug so there are no high voltage wires that ever need to be replaced.
  • Most of today's cars and trucks have the spark plugs buried underneath the overhead cams, making them hard to replace. Accordingly, many vehicles are now equipped with platinum tipped spark plugs that will last for 100,000 miles or more.

So, thanks to advances in technology, a regular "tune up," as we remember it, is no longer required. However, it is still important to follow the recommended maintenance service intervals for your vehicle. Not only does this honor the warranty, but most importantly, it will ensure that your car performs safely at peak efficiency.

Diesel Fuel Service Tips for Winter Weather!

Winter storms have come and gone, and will probably come again. What steps are you taking to ensure your diesel engine starts and runs properly? Here are a few diesel fuel service tips to help keep your diesel engine running smoothly and make it through the cold winter temperatures:


If you are looking for quality Oil Change Coupons Milton-Freewater OR than find our Wentland Diesel Fuel Injection Milton-Freewater OR Shop. Meet our Brake Repair Milton-Freewater OR Mechanic to solve any of your car problems.
  • Treat your fuel with a good quality winter additive to lower its pour and cold filter plug points and improve cold weather starting.
  • Check your fuel filter element frequently and change it as needed.
  • Consider an in-line fuel heater.
  • Consider an engine block heater when the temperatures drop below the teens.
  • In an urgent situation, an alcohol additive may be added to the fuel tank and filter element to keep your fuel from gelling and clogging the fuel filter. This should start the fuel flowing again after a few minutes. Warning, heavy alcohol use may damage non-metal materials in your fuel system.

There are generally three things that effect the starting of a diesel engine:

Cranking speed. Commonly, a diesel engine needs to crank at approximately 200 RPM to start properly. Things to check are: the condition of your batteries, the battery cables and the starter.

Compression. Diesel engines rely on the heat generated from compressing the air in the combustion chamber to ignite the fuel. If the compression is low, the heat is low as well. An engine which uses glow plugs to start when the engine is cold may experience a hard-start condition when the engine is warm if the compression is low.

Condition of the fuel system. If the fuel pump is weak or the conditions of the injectors are poor, the engine may be hard to start. On some fuel systems, hard-starting may be the first sign of a fuel pump that is failing. If the fuel tank is located lower than the fuel injection pump, a leak in the fuel system may allow the fuel to drain back to the tank when the engine sets for several hours.

Hard starting, no start, blue or white exhaust smoke, and rough running are signs that you need a diesel fuel service performed by a qualified technician.
