What kind of antifreeze should I use on my Duramax Diesel?
You should only use silicate-free anti-freeze in diesel coolant systems. There are many other brands besides GM DexCool if you don’t want to use that. If you have the radiator serviced as recommended it does not cause any problems.
Why does my Duramax engine have low coolant level?
After the engine has been thermally cycled, air rises and causes the coolant to become lower than when initially filled. During a Pre-Delivery Inspection (PDI), the coolant level may appear low, but is at a level high enough to keep the Low Coolant message off.
Where is the coolant sensor on a Duramax Diesel?
7) The horizontal line is a baffle inside the surge tank that keeps the coolant from sloshing inside the tank and tripping the coolant level sensor, which is located below the baffle. A full coolant level will show the coolant at the bottom of the radiator surge tank fill neck.
Is the coolant level on my Silverado Sierra low?
A Low Coolant message may be displayed on the Driver Information Center of some 2017-2018 Silverado and Sierra models equipped with the 6.6L Duramax diesel engine (RPO L5P). An inspection of the radiator surge tank may appear to show a low coolant condition.
Where is the low coolant message on a Duramax?
During PDI, coolant should be added to fill the upper chamber of the radiator surge tank. (Fig. 6) A coolant level that is low enough to turn on the Low Coolant message will be below the horizontal line across the radiator surge tank. (Fig.
A Low Coolant message may be displayed on the Driver Information Center of some 2017-2018 Silverado and Sierra models equipped with the 6.6L Duramax diesel engine (RPO L5P). An inspection of the radiator surge tank may appear to show a low coolant condition.
When to add coolant to radiator surge tank?
During a Pre-Delivery Inspection (PDI), the coolant level may appear low, but is at a level high enough to keep the Low Coolant message off. During PDI, coolant should be added to fill the upper chamber of the radiator surge tank.
What’s the difference between the LMM and the LBZ?
Compared to the LBZ, the LMM added active regeneration cycles to the diesel particulate filter (DPF) system. Outside of this complex emissions system, the LMM remained very similar to its predecessor. While the power output was increased to 365hp and 660lb-ft of torque, its fuel economy suffered materially due to the new DPF system.
What kind of coolant do you put in a Camaro?
Anything after ’96 has that crap in the radiator. It ate away my 96 Camaro’s gaskets, and left so much sludge in my in-laws Olds Intrigue, they had to replace the water pump and radiator. Prestone makes a coolant that can be mixed with any existing coolant. I also added DEI Cooling Additive for ”superior cooling and lubrication”.
Why is the LBZ engine better than the LLY?
To support the power increase over the LLY model, the block was improved, the rods were forged, and the engine was overall built to withstand more power. Because of this, the LBZ is a favorite amongst diesel enthusiasts because of its bolt-on mod performance capabilities.
Why does my LBZ diesel engine keep leaking?
The lines on the Duramax LBZ have a design fault at the “crimp” to where the crimp isn’t suitable enough to hold onto the line and prevent fluid from leaking. Leaks are most common when the fluid is cold and on trucks running high idles. Some folks have a consistent leak while others tend to only leak when the engine is cold.
What happens when water pump on LBZ goes bad?
On the LBZ, and all Duramax engines for that matter, the impeller inside the water pump is made of plastic. The impeller is like a little rotating fan that is responsible for actually forcing the coolant through the system. If your impeller breaks or goes bad, the coolant won’t flow through the engine.
What makes the LBZ the most sought after Duramax?
The tune-only power capabilities combined with its reliability are what make the LBZ the most sought after Duramax today, nearly 14 years after it stopped production. With a strengthened block and good internals, the LBZ is easily capable of surpassing the 300,000 mile mark with sufficient maintenance and care.
