Is green antifreeze silicate free?
It offers five years or 150,000 miles of protection and is silicate and phosphate-free.
Does green antifreeze have silicates?
The green antifreeze contains silicates, phosphates and / or borates as corrosion inhibitors to keep the solution alkaline. As long as the solution remains alkaline, corrosion is controlled and the system is protected.
What antifreeze is silicate and phosphate free?
Prestone Regular or 50/50 is a silicate free OAT antifreeze. It uses phosphates to replace the silicates.
What Colour is silicate coolant?
This means that if you drive an older model car, it likely still uses green antifreeze. This type of coolant is sometimes referred to as conventional low-silicate coolant. This is because it uses silicates as corrosion inhibitors. Historically, a green-dyed coolant was designed for cars and small trucks.
Can I mix different coolants?
Mixing different engine coolants or using the wrong coolant can impair the performance of the special additive packages; this can result in increased corrosion to the radiator. Using the wrong engine coolant can gradually lead to corrosion and damage to the water pump, radiator, radiator hoses and cylinder gasket.
Is there any silicate in Prestone Green antifreeze?
If you are looking for low/no silicate ethylene glycol (green antifreeze) be cautious to what you pick up. If it says low-silicate but does not say “meets ASTM-4985”, then it is not low silicate. Prestone in the yellow bottle is the biggest offender- it is by no means low silicate.
What kind of coolant to use with silicate?
One undesirable property of silicates is that they are abrasive and over time can contribute to wear of water pump seals, as well as other components. I would use the Valvoline Zerex G-05 coolant, low silicates and the same formula as the Mercedes coolant, but at a cheaper price.
Are there any drawbacks to using silicate in antifreeze?
But silicate has the drawback I mentioned, plus it is also inherently abrasive. This is one of the main reasons for the trend away from traditional green silicated ethylene glycol to the extended-life OAT (organic-acid tech) antifreezes, not to mention they have short service lives.
Is there a silicate in Honda anti freeze?
Honda anti-freeze is silicate free. Honda says the silicates are hard on aluminum engine parts. I know a lot of mechanics i’ve talked to about this don’t think it matters. My landlord had an Acura Integra that had a whole eaten into the engine from the anti-freeze.

Are there any silicates in Honda Genuine antifreeze?
Diesels prefer NON Silicate formulas. It’s the silicates that form the gels. The CAT EC-1 formula is CARBOXYLATE and TRIAZOLE. It is also approved by Cummins, Navistar,etc. From Honda- “Honda Genuine Antifreeze/Coolant Most other coolants contain borates and/or silicates which can act as abrasives in your Honda’s cooling system.
