Accordingly, can you use regular antifreeze in a diesel engine?
Engine coolant maintenance is just as important as an oil change. In fact, the coolant condition in a diesel engine may even be more important than in a gasoline engine. Today's antifreeze-coolant not only protects from freezing in the winter months, but also helps protect diesel engines from common cavitation issues.
Beside above, can I add water to my diesel coolant? A 50/50 mix of heavy-duty antifreeze/coolant and clean, quality (distilled, de-mineralized, or de-ionized) water with supplemental coolant additives (SCA's) is required for all heavy-duty engines. Water (without antifreeze/coolant) with 6% SCA additive is no longer recommended and is not an acceptable coolant solution.
Similarly, what is the best antifreeze for diesel engines?
Best Diesel Option: Zerex G-05 Antifreeze/Coolant The Zerex G-05 Antifreeze/Coolant works in both gasoline and diesel vehicles, but contains some additives that will benefit diesel engines in particular.
How does diesel get into coolant?
Diesel flows thru the head into the injectors. Only a couple ways to get into the coolant system. Either leaking injector cups, cracked head, possibly the Davco, but not likely. A blown head gasket won't pass diesel into coolant system.
