Is there a special antifreeze for diesel engines?
The difference between the antifreeze used in a diesel engine and that used in a conventional gas engine is that diesel antifreeze contains a special additive that protects against erosion on cylinder walls.
What color is antifreeze for diesel?
OAT coolants are designed for use in heavy and light-duty diesel engines, as well as natural gas and gasoline engines. Color: orange or red, but can also come in yellow, blue, red and dark green depending on the manufacturer.
Can you use 50/50 antifreeze in a diesel?
Prestone ® HD 50/50 Prediluted NITRITE FREE Extended Life (ELC) Antifreeze/Coolant is intended for use and compatible with ANY nitrite free HD Organic Acid Technology (OAT) coolant in ANY diesel-powered commercial vehicle engine or stationary engine with aluminum or other engine metals.
Can you use green antifreeze in a diesel engine?
Valvoline™ ZEREX™ HD Pre-Charged Green Antifreeze/Coolant is a low-silicate formula charged with special inhibitors to protect heavy duty diesel engines from liner pitting and corrosion.
Can you use Prestone antifreeze in a diesel engine?
Prestone Command HD Coolant/Antifreeze is also compatible with all OAT Extended Life HD Antifreeze/Coolant, and can be used by any diesel engine in any industry. The formula is available as Ready to Use 50/50 and Concentrated.
What is the preferred pH level of coolant in a diesel engine?
Therefore, the pH value in an ideal cooling system always needs to be between 8 and 10. To achieve this, you need buffers in your cooling fluid to neutralise the formation of acids or alkalis.
What happens if you use the wrong color antifreeze?
If you do mix different-coloured coolants they generally do not mix well and some can form a gel-like substance. This will halt coolant flow, causing blockages that can lead the engine to overheat, as well as damage to the radiator, water jackets and heater core. Also, the water pump can overheat and fail.
What kind of coolant is pink?
The Colors of Coolant
|HOAT (Hybrid OAT)||Silicates & Organic Acids||YELLOW|
|HOAT (Hybrid OAT, Phosphate-free)||NAP Free||TURQUOISE|
|P-HOAT (Phosphated HOAT)||Phosphates & Organic Acids||PINK / BLUE|
|Si-OAT (Silicated HOAT)||Silicates & Organic Acids||PURPLE|
What is green antifreeze used for?
Green antifreeze is made with special tweaks to the formula specifically to help prevent the corrosion of metals in a vehicle’s cooling system. That older formula is typically meant for vehicles made before the year 2000, which were built with more steel and copper components than modern vehicles.
What kind of antifreeze does a Detroit Diesel take?
Detroit Diesel markets OAT-inhibited ethylene glycol coolants—DDC POWER COOL Plus and POWER COOL Plus Marine (30% glycol, 70% water). POWER COOL Plus coolants contain all of the required inhibitors. If a non-DDC® OAT antifreeze is used, it must conform to TMC RP-338 specification.
What’s the difference between Prediluted and concentrated antifreeze?
Concentrated coolants are packaged to be diluted to a specific coolant concentration ratio i.e 50% by mixing with water. Pre-mix coolants are already diluted with water at a preset ratio normally between 33% to 50%.
Is Peak antifreeze phosphate free?
Compatible for use in all automobiles and light-duty trucks. Yellow color will not change the current antifreeze color when used for topping-off. Provides 150,000 miles or 5 years of maximum protection when a complete cooling system flush and fill is performed. Features a phosphate-free and silicate-free formula.
Is diesel coolant the same as gas?
Today, there are two: The green coolant and the orange colored coolant, which is also known as Dexcool. Let’s look at these more closely. The green coolant is an inorganic additive technology (IAT). With this type of coolant, phosphates along with silicates are added to ethylene glycol.
