Why does the Duramax never have a lift?
Why does the Duramax never have a lift?
A well-documented problem on any Duramax whether it has the CP3 or 4, is a loss of rail pressure during acceleration once the truck has a higher power tune on it, and I have experienced this myself many times.
Where does the fuel go in a Duramax?
It all starts in the tank, which is where the fuel is stored whenever you fill up. Depending on the model, you might have between 25 and 40 gallons of capacity, and on most trucks there is a low-pressure fuel pump which sits inside the tank and pushes the fuel toward the engine at a relatively low pressure.
Why does my car stall at low rpm?
The will likely force your computer to stall the engine and only allow it to run at low RPMs, which means the car will only move at slow speeds. This is a safety feature enforced by the computer so that your engine doesn’t get too damaged.
What causes low fuel pressure on a Duramax?
If you remember the basic fuel system anatomy, you’ll recall there is a fuel pressure relief valve in the rail, and occasionally it can open prematurely and cause low rail pressure. The one way to spot an failing pressure relief valve it to fire up your scan tool, recreate the symptom, and record another data log.
What happens when a Duramax engine goes down?
Not only does this mean game-over for the engine, but it results in a truck that’s down for weeks (if not months) and a huge chunk of change missing from your wallet. The failure is most common in higher horsepower engines, but can still occur in moderately modified and even stock power plants.
What causes a Duramax to overheat in the summer?
Overheating typically occurs while towing in the Summer months, and is most prevalent in 2005 or earlier models (2006+ models received a larger radiator and fan). Overheating often occurs as a result of a fan clutch failure, preventing the engine fan from providing supplemental airflow as necessary to keep the engine from overheating.
Are there any problems with the Duramax water pump?
This seems to be inherent of the factory water pump design. Overheating issues with the Duramax diesel seems to be a hit-or-miss problem; some owners experience it, while others never will. Regardless, it’s more common with the Duramax than other engines.
What to do if your Duramax crankshaft is weak?
The ultimate fix for the weak factory crankshaft is to replace it with a stronger unit that’s been internally balanced. The billet Callies crankshaft available through Wagler Competition Products is machined from triple heat treated 4330V steel and features reduced rod journal widths for improved strength (which calls for narrower rods).
