List Of Duramax Years To Avoid
Generally, it would help to avoid the 2001-2010 Years Duramax model. The older version can’t perform well today, and its towing capacity has become too low.
There would be a chance to break tie rods, leak water pumps, and damage fuel injectors and head gaskets in any challenging condition. So, you need to avoid the below list and focus on the upcoming Duramax model for better performance.
- 2007-12 Duramax LMM
- 2006-07 Duramax LBZ
- 2004-05 Duramax LLY
- 2001-04 Duramax LB7
Note: To get better performance in all road conditions, you must avoid these years’ Chevrolet Silverado HD, Chevrolet Kodiak, GMC Sierra HD, and GMC Topkick Duramax. Otherwise, you will fall into many unexpected situations when you take a long drive.
Why Should Avoid 2001-2010 Duramax Year?
If you are a Duramax lover, you should choose the upcoming model. In the older version, like the 2001-2010 years, you won’t get the best performance, and it’s tough to replace the damaged part for lack of production. Not only Duramax, but you should also avoid GM vehicles from 2001-to 2010.
Let’s check why we avoid the 2001-2010 years Duramax model.
In the 2001-2010 years the Duramax model has not included an effective cooling system. As a result, when it takes a long drive, the engine overheats and can damage a huge 6.6L Duramax LB7. So overheating problems can cause engine failure when you take a long drive.
Failure Fuel Injector
The old Duramax used the CP3 pump subjected to tremendous stress when moving at 23,000 psi. So when it damages, it takes more than 16 hours to replace the lift pump and other components. So here happen some unexpected issues with fuel filter engine oil and injection pump.
- Drop-in Performance
- Affluent Bank Codes
- Engine Misfires
- Sloth Erratically
- Diesel Exhaust Fluid
Damage Head Gasket
The construction of the head gasket is honestly faulted here when it bursts. GM Duramax placed here a steel gasket with a restraining ring that is not effective.
The ring features around the cylinder bore are the fundamental cause of the natural deterioration over time.
Snapped Tie Rods
You won’t get enough solid or durable tie rods in the old Duramax. It won’t take more weight, and the towing capacity is too low.
The strict road condition creates more pressure on the tie rods and can be broken. That’s why the older Duramax is not perfect in all road conditions.
Water Pump Failure
In the 20010-2010 model, the water pump would leak for its plastic body and weak coolant seal. Due to regular Lar and tear, the coolant seal will lose its temper and can’t protect against a fuel leak. For the long drive, there can be a great chance of leaking water that is not good.
In the old version, Duramax used cast iron material and was not formed for all conditions. For the weather demand and critical situations, the metal would be damaged and cause a high cost to repair or change the vital surfaces. That’s why the old LMM Duramax is not usable today in general motors.
Why Is The 2001-2006 Model Different From 2007.5-2010?
Now it’s clear to us that the 2001-2010 years model is not acceptable today. But there is a difference between the 2001-2006 and 2007.5-2010 versions of Duramax.
Though they are genetically formed in the same sequence, 2001-2006 years Duramax is better than the 2007.5-2010. Rather the 2007.5-2010 years Duramax is more updated from 2001-2006. Let’s check the main difference.
It’s the most valuable part to discuss on the Duramax decades of revaluation. In the 2001-2006 years model, you get the best fuel economy rate, and at that time, it was too reliable to absorb oil.
That’s why it would be more prevalent at that time, and still today, it takes a low fuel system and saves fuel cost coherently.
On the other hand, from 2007.5-to 2010 years Duramax was not effective in the parameter of fuel economy.
Though these models were upgraded than previous models, the fuel economy rate wasn’t reasonable. These models’ accountability would lower day by day and are still not recommended.
