What does coolant silicate drop out cause?
Silicate drop-out. Excess phosphates and silicates will drop out, causing deposits or a sludge-like consistency that can result in premature water pump failure, radiator blockages, heater core problems and extensive down time.
What does silicate do in coolant?
Currently, these green coolants typically use a phosphate/ silicate mix as the main components in their inhibitor system. Conventional inhibitors like silicates and phosphates work by forming a protective blanket that actually insulates the metals from the coolant.
What is low silicate coolant?
Prime® Antifreeze/Coolant Conventional Green Low Silicate Formulation is an ethylene glycol based product which meets or exceeds ASTM requirements for use in cars, light-duty and heavy-duty trucks. It contains inhibitors to prevent rust and corrosion for all cooling system metals including aluminum.
What is silicate drop out?
That is called silicate dropout, it happens when the antifreeze/coolant has been used beyond it life expectancy and the additives break down. This goo would have ended up plugging the system, plus the silicate is part of the corrosion inhibitor package.
What would be the most likely outcome if a radiator cap pressure valve fails to seal?
Which would be the warmest portion of a typical downflow type radiator when the engine is at operating temperature? If a radiator cap pressure valve fails to seal, would be the likely outcome? Coolant circuit that allows coolant to flow within the engine block and cylinder head during warm-up.
How long does green coolant last?
As we mentioned earlier, your engine will suffer if you run out of coolant. Thankfully, both green and orange antifreeze last a while. How long? Green for about 3-years or 36,000 miles, and orange for 5-years or 150,000 miles.
What’s the difference between coolant and antifreeze?
Well, antifreeze and engine coolant are similar, but not the same. Antifreeze is a concentrated, glycol-based liquid that must be diluted with water before use – at which point it is referred to as coolant. Alternatively, you can purchase pre-mixed engine coolant, a ready-to-use solution of antifreeze and water.
Is used as a coolant?
Water is the most common coolant. Antifreeze, a solution of a suitable organic chemical (most often ethylene glycol, diethylene glycol, or propylene glycol) in water, is used when the water-based coolant has to withstand temperatures below 0 °C, or when its boiling point has to be raised.
What kind of coolant does Cummins cooling system use?
Our comprehensive line of cooling system products includes everything you need to ensure an easy, trouble-free cooling maintenance program: nFully formulated heavy duty antifreeze coolants nSupplemental coolant additives (SCAs) nCooling system cleaners nCoolant filters – chemical and non-chemical nField and laboratory testing Easy Maintenance
What kind of coolant should I use for a natural gas engine?
Fleetguard coolants are suitable for use in all gasoline, diesel, and natural gas engines. Unmatched Protection In addition to providing superior freeze and boil over protection, Fleetguard products protect your engine from the most damaging cooling system problems, including:
What should I do with my coolant system?
Restore your cooling system back to its optimum condition. Fill your system with long life coolant that offers maximum engine protection and is safe for you and the environment. Properly top up your system using the pre-mixed coolant, maintain additive levels at regular service intervals, and change filters.
What causes corrosion in a Cummins cooling system?
Corrosion products and tiny metal particles begin to circulate in the cooling system, causing erosion damage to mechanical parts. Piston-slap causes liner vibration which creates a vacuum and formation of tiny vapour bubbles at the liner surface.
