Why does my CP4 pump fail?

This may be due to the CP4 pump failing. Your CP4 pump is your high-pressure fuel pump. This pump converts low fuel pressure into high fuel pressure. Your CP4 may fail due to many reasons.  The CP4 pump may fail due a lack of lubrication to the pump itself. This lack of lubrication can be from ultra-low sulfur diesel. This diesel does not have all the lubrication properties that are needed for the pump to work correctly. It can also fail due to water in your fuel system. The water will take away the lubrication properties of your diesel and this will cause the pump to fail. Water in your fuel can cause failure. Your fuel filters help to filter out the water. If you fuel filters are old, then they will not filter out the water properly.  Your CP4 pump has a camshaft with lobes inside the pump. When this component starts to fail it causes metal debris. This debris is introduced into the fueling system including your fuel injectors, fuel tank, fuel lines, anything that fuel go ... read more

How do I take care of my turbocharger?

How do I take care of my turbocharger?

A turbocharger loves clean engine oil and coolant. Having your engine oil changed at the recommended interval will keep your turbocharger working properly. Your engine oil should be changed every 5,000 miles and we always recommend using full synthetic engine oil. This will help to prevent the breakdown of the engine oil due to the higher temperatures. We also recommend a cooling system fluid service every 36 months. Over time your coolant stops protecting your engine due to electrolysis and corrosion. The corrosion-inhibiting components in your coolant break down and stop protecting your engine from damage. Some engines may need a corrosion and anti-cavitation additive.

What does a turbocharger do?

What does a turbocharger do?

A turbo charger compresses the air and forces it into the engine. When done properly this can dramatically increase the amount of power that a small engine can produce. Smaller engines are often more fuel efficient, this give you the benefit of more power and still having great fuel economy. Along with a turbocharger a few other components are needed to make it as efficient and powerful as possible. Including an intercooler, hoses, and pipes. Rapidly compressed air gets very hot, decreasing the temperature of the air through the intercooler before it goes into the engine increasing density and giving the engine more power.

How often should I change my diesel fuel filter?

How often should I change my diesel fuel filter?

We typically recommend that you change your fuel filter every 10,000 to 15,000 miles. If you think you have gotten a bad tank of fuel then we recommend that is changed again to prevent issues with your fuel system. Your fuel filter is sometimes a water separator on certain makes and models. Keeping water out of your fuel system is important. If your fuel is contaminated it can cause your fuel injectors to fail, high-pressure pump failure, low-pressure pump failure, fuel pump failure and possible engine damage. Give us a call and let us take care of you. Happy Adventures, Heather

Can I run bio-diesel instead of regular diesel

Can I run bio-diesel instead of regular diesel

Can I run bio-diesel instead of regular diesel This depends on the age of your engine and fuel system. Many of the newer diesels that were made after 2000 do not tolerate bio-diesel. The decreased lubrication caused by bio-diesel fuels can lead to high pressure pump failure, fuel injector failure and possible damage to your engine. Every engine is different and it’s best to ask if it’s right for your engine before using it. Give us a call and let us take care of you.

Why does my diesel have a misfire?

Why does my diesel have a misfire?

Your diesel could have a misfire due to a faulty fuel injector. Your fuel injector can fail due to do contaminated or bad fuel. Dirty engine oil on certain models, electrical failure or a mechanical failure of the injector. To know why we need to run tests to determine why you have a misfire and to prevent potential engine damage.  We start with scanning the ECM for diagnostic trouble codes this tells us if the ECM recognizes the issue as a misfire or as an electrical issue. From there we then will either check electrical connections or take a fuel sample. The wiring harnesses for some fuel injectors can come unplugged causing a misfire. The wiring harness can also become damaged due to rubbing or other damage such as rodents. Sometimes this can be repaired, other times it will need to be replaced.    When we take a fuel sample, we check for water contamination and other possible contaminates. To determine if the low-pressure fuel system is working properly, we test to ... read more

Why is my diesel blowing white smoke?

Why is my diesel blowing white smoke? Your engine may be blowing white smoke due to unburnt fuel. Your engine may have unburnt fuel due to a fuel injector O-ring. If one of the O-rings is damaged it will allow fuel to go past and then it will go into the cylinder and this will cause the white smoke. Give us a call and let us take care of you.

My diesel is losing power, Why?

When does your diesel lose power? If it is losing power while accelerating then it could be that your fuel filter is plugged. Your fuel filter catches debris in your fuel. This allows your fuel system to work properly and more efficiently. When your fuel filter is restricted then it caused the other components to work harder. We recommend your fuel filter be changed every 10,000 to 15,000 miles. If you're unsure of the quality of the fuel you're getting then it's better to change it more often. If you're having issues with lack of power with your diesel give us a call and let us take care of you.  Happy Adventures, Heather   Our specials can be found here - Specials - J & H Automotive, Inc Ready to make an appointment … Appointments - J & H Automotive, Inc ... read more

Why Does My Diesel Crank and Not Start?

The good news is that it cranks. Now to find out why it doesn't start. I know it's frustrating when you go out to your vehicle, and it will not start. It happened to me recently too. Let's chat about a few things that you can troubleshoot before you call the tow truck.   First, let's make sure that you have fuel. Check the fuel gauge to see how much fuel is in the tank. If it's on empty, then fill her up and try again. If the problem persists, then move on to the next step. Diesel engines do not like to run low on fuel and this could be one culprit.   Next, check all of your fuses and make sure they are not blown. A blown fuse can cause all sorts of problems, including a vehicle that won't start. If you find a blown fuse, replace it with a new one and see if that fixes the problem.   With a diesel that cranks and does not start that is about all you can do before you need to have it towed in. It could be a fuel delivery issue, where it is n ... read more
