Why is silicate added to antifreeze?

In newer automotive applications, silicates are needed to protect aluminum engine parts and radiators from corrosion, and are used in virtually all antifreeze mixtures in varying forms and amounts. ... Silicate gel buildup greatly reduces heat transfer from the engine castings to the coolant.

Is Autozone antifreeze silicate free?

All coolant of this variety is either silicate free, phosphate free, or both, and is designed specifically to meet the needs of that particular manufacturers' testing.

What type of coolant contains phosphate and silicate?

Most antifreeze products sold for the past several years have been the traditional "green" coolant. This type is good for two to three years and up to 30,000 miles. The green antifreeze contains silicates, phosphates and / or borates as corrosion inhibitors to keep the solution alkaline.

Is green antifreeze silicate free?

Valvoline^™ ZEREX^™ Original Green Antifreeze / Coolant provides: Low-silicate chemistry for heavy-duty applications with use of SCA. Corrosion inhibitor package provides rust and corrosion protection.

Does Prestone antifreeze contain silicates?

This Prestone AF2000 is the newer breed of "organic acid technology" (OAT) antifreeze/coolant. (I'm pretty certain it's their DexCool formula, actually; this formula contains no silicates, phosphates or borates. This formula is orange in color, but that means nothing--it's only a dye.)

Why are some coolant silicate free?

Firstly, the car coolant MUST contain ethylene glycol. ... Secondly, the coolant MUST NOT contain any silicate. Silicates are anti-corrosive chemicals that are quite helpful in cars as they help inhibit aluminum corrosion. For motorcycles, however, they can attack your water pump or seals.

Is OAT coolant silicate-free?

A general guide to antifreeze

Cars made after 1998 normally need antifreeze that uses silicate-free, organic acid technology (OAT). These types of antifreeze offer better corrosion protection so that parts don't need to be changed as often.

Is OAT coolant the same as Dexcool?

Dex-Cool® is an OAT, an ethylene glycol based antifreeze that is nitrite-, borate-, phosphate-, nitrate-, amine-, and silicate-free with the same metal wear protection as an IAT antifreeze. Dex-Cool® is trademarked by GM. HOAT (Hybrid Organic Acid Technology) Mixture of OAT and IAT antifreeze.

Can I mix Peak antifreeze with Dexcool?

The universal coolants (Peak Global, Prestone All Makes/Models) can be mixed with Dexcool as well as conventional coolants.

Which antifreeze is phosphate free?

Shell HD Phosphate Free Antifreeze/Coolant 50/50 is a phosphate free, fully formulated antifreeze/coolant (AFC) pre-charged with supplemental coolant additives (SCAs) and pre-diluted to a 50/50 premix level with high quality water. DO NOT DILUTE - No further water dilution is needed under normal circumstances.

What brand antifreeze has ethylene glycol?

Havoline® Conventional Antifreeze/Coolants are low-silicate, ethylene glycol-based multi-purpose coolants, available as concentrates or 50/50 pre-diluted products. They are for use in automotive engines where silicates are needed and with supplemental coolant additives (SCAs) addition in heavy-duty diesel engines.

Is ethylene glycol silicate free?

It incorporates state-of-the-art organic acid technology in an ethylene glycol base for protection of all cooling system metals including aluminum. It meets the silicate-free requirements of the Japanese automobile manufacturers and phosphate-free requirements of European automobile manufacturers.

Does OAT coolant have silicates?

A Hybrid OAT (HOAT) coolant is also an option. ... This type of coolant mixes technology from the first two to create a low-silicate, nitrite technology. It contains both silicates and organic acids as inhibitors. Ford, Chrysler, and some other European companies recommend this type of coolant for their cars.

Is Prestone green silicate free?

Prime ^® Conventional Green antifreeze+coolant is the original coolant. This low silicate formula, when used as directed, will provide protection for a minimum of 1 year.

Is Ford orange antifreeze the same as DexCool?

You should know that the term "orange coolant" has come to mean a DexCool-approved brand but that doesn't mean it's really true. ... All DexCool-approved coolants to date use two organic acid rust/corrosion inhibitors, one called sebacate, the other called 2-EHA (which stands for 2-ethylhexanoic acid).
