Overview

Auto coolants to be simple. Every two years you your out your old coolant and it with new you got from your supply store.

Recently for GM, 1997-98 for VW, 2002-03 for Ford, for Chrysler. ) manufacturers started extend life coolants different anti-corrosives for longer (because people neglected to it every two years). Some hybrids with combinations of the new acid technology (OAT) and old like phosphates. The europeans BMW) didn’t like because of the reaction of their water with phosphates; The (Honda, Toyota) on the other liked phosphates because worked better than So manufacturers started selling formulas in a variety of colors than the traditional green and that you use their brand, was, of course, more

Many of the owner’s manuals say something like Subaru’s: The Genuine Coolant containing and anti-rust agents is especially for SUBARU engine, which has an crankcase. Always use SUBARU Coolant, since other may cause corrosion.

Most experts agree you have to use the manufacturers coolant. The new life coolants from Prestone. will be just as

The new antifreezes or Extended Life Coolant (XLC or ELC) use Acid Technology (OAT) neutralized organic acids acid salts) that engine parts from instead of the inorganic inhibitors as silicates, phosphates and / or borates in the old and yellow) antifreezes.

OAT is recommended in with aluminum components or radiators) such as Subarus and VWs Borates can be bad for them. OAT coolants have extended lives, up to mi.

Hybrid OAT (HOAT) coolants, as Zerex G-05Ё. Use organic but not 2-EHA (2-ethylhexanoic acid) organic acids are used). OAT coolants add some silicate to quick-acting protection for aluminum Several web sites said you avoid mixing traditional (blue, yellow or green) Organic Acid Technology (orange, red, pink) or (yellow) coolants. The OAT will precipitation of silicates in the green and corrosion protection is greatly

However, many of the aftermarket (e.g. Prestone, Zerex, now have a universal coolant claim is OK to mix with anything.

to Car Talk SAE (the Society of Engineers) said that you can mix up to 15 percent traditional coolant in OAT coolant before you have any effect on the corrosion inhibitors.

Following are statements from a of web sights such as Car Talk. Lube, the back of anti-freeze and other sources. Some may be years old, so don’t into consideration the new universal

As of 2006 I found a lot of conflicting on the Internet and in talking to dealers and shops.

There were that topping off your with the wrong kind or your coolant with a kind without completely your system could your engine and void warranty.

Many of the aftermarket (e.g. Prestone, Zerex, now have a universal coolant claim is OK to mix with anything. Lube carries 3 types: 1. 2. Dex-Cool (GM) and 3. Prestone OAT for Chrysler. If you have a VW or Audi you bring your own coolant and will use it with their machine.

The bottom line is to check owners manual (or a label to your radiator fill cap or reservoir); If it says you must use a (long life or other don’t use the old anti-freeze you’ve had in your garage for the last 8

However, most of the experts you can use the new

Coolants have several Anti-freeze, anti-corrosive, water lubricant anti-foaming:

Anti-freeze Almost all use ethylene glycol or propylene glycol (PG) for the antifreeze base.

Anti-corrosion


Conventional — Green/Yellow contains silicates, phosphates and / or as corrosion inhibitors to keep the alkaline. This is called Additive Technology (IAT )

car makers like VW specify additives lacking in phosphates and borates and low silicates ( such as G11 (blue) ) because their is harder and it reacts with to create aluminum phosphate or and magnesium deposits.

See more on problems with at autorepair.about.com

The Japanese disagree and mixtures high in phosphates and low in and silicates because they lack of maintenance will borate corrosion.

Tap water in America also contains but isn’t as hard as European tap so phosphates are considered okay to use

Organic Acid Technology or Extended Life Antifreeze ( XLC or ELC ) antifreeze contains neutralized acids (organic acid that protect engine from corrosion. These Havoline® XLC, GM’s (also manufactured by Texaco) and G12.

Honda has an extended-life OAT that is dyed dark and does not contain 2-EHA .

OAT such ingredients as sebacate Honda), 2-ethylhexanoic acid and other organic acids, but no or phosphates (except in the case of pink extended-life coolant, adds a dose of phosphate to its OAT-based antifreeze).

Organic inhibitors do not deplete as as the inorganic inhibitors used in coolants.

OAT is recommended in engines aluminum components (heads or because Borates can be bad for them.

OAT also have extended up to 150,000 mi.

OAT corrosion inhibitors excellent long-term protection for and cast iron, but may not be the best for older cooling systems have copper/brass radiators and cores, especially the lead used in them. It depends on the

Hybrid OAT (HOAT) coolants, as Zerex G-05® Use organic but not 2-EHA (2-ethylhexanoic acid) organic acids are used). OAT coolants add some silicate to quick-acting protection for aluminum Silicate also helps surface erosion caused by in the water pump. Hybrid OAT are currently used by many vehicle manufacturers (BMW, Volvo) as well as Ford and

Toyota adds some to their hybrid.

The new universal use unique OAT-based corrosion with proprietary organic (such as carboxylate) to provide spectrum protection.

Colors (Dyes to distinguish

Note: GM converted to OAT (Organic Technology) in 1994-96, but some and models were still conventional coolants in 2005, so your owners manual to see you should be using.
