How do you test OAT coolant?
The only accurate way to test for this concentration (and freeze point) is to use a refractometer. The old-style floating ball testers will not work properly with modern OAT, NOAT, and HOAT formulations. Generally, there are two types of refractometers that you should use with your modern coolant mixtures.
What color is OAT coolant?
ORANGE
The Colors of Coolant
| TYPE | INHIBITOR TECHNOLOGY | COLOR |
|---|---|---|
| OAT (Organic Acid Technology) | Organic Acids | ORANGE |
| HOAT (Hybrid OAT) | Silicates & Organic Acids | YELLOW |
| HOAT (Hybrid OAT, Phosphate-free) | NAP Free | TURQUOISE |
| P-HOAT (Phosphated HOAT) | Phosphates & Organic Acids | PINK / BLUE |
What does OAT mean in coolant?
Organic Acid Technology
ES Compleat™ OAT (Organic Acid Technology) is a Life-of-the-Engine organic additive fully formulated extended life Ethylene Glycol (EG) antifreeze/coolant.
Can you use OAT coolant in all vehicles?
Organic acid technology (OAT) This coolant is typically compatible with cars manufactured by GM, Saab and VW. Unlike IAT coolants, OAT coolants are designed for newer cars, usually, those made in the 2000s or later. OAT uses organic acid to help protect your engine from corrosion.
How do I check the pH level in my coolant?
Propylene glycol coolants may be tested with a paper test strip. The test strips are dipped into the coolant and then the color of the strip is matched to the chart to determine the condition. This method measures the pH of the liquid, an indication of the acidity level.
Do coolant test strips work?
Although strips test the freeze point of antifreeze, it can also determine if the antifreeze coolant has become corrosive or if it has anti-corrosive life left to protect the engine. Antifreeze test strips are a fast and accurate method of checking your antifreeze.
What coolant is compatible with Mopar oat?
We recommend using Mopar Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT (Organic Additive Technology) that meets the requirements of FCA Material Standard MS. 90032. Mix a minimum solution of 50% OAT engine coolant that meets the requirements of FCA Material Standard MS. 90032 and distilled water.
Can you mix different OAT coolants?
OAT coolants use organic acids in order to prevent corrosion. Some people believe that they can mix the two. This is a mistake and can lead to expensive repairs. The two coolants should never be mixed together as they do not react well.
How often should OAT coolant be changed?
Most manufacturers of OAT-based antifreeze claim their products have a service life of five years, or 100,000 to 150,000 miles — whichever comes first (that’s the important part). HOAT-based antifreezes also contain an OAT additive package, plus an additional dose of silicates.
What is the difference between green and orange antifreeze?
What’s the difference between green and orange coolant? Both orange and green antifreeze serve as engine coolants, designed to keep it from freezing or overheating. They also defend the cooling system against corrosion. Green is formulated for the former, and orange, the latter.
What happens when you mix green and orange coolant?
The green and orange coolants do not mix. When mixed together they form a gel-like substance that stops coolant flow, and consequently, the engine overheats.
How much does it cost for a coolant flush?
This can include four gallons of coolant, cleaner, and a conditioner in the total radiator flush cost. The typical price for the radiator flush cost at a standard mechanic shop, like your local store, will typically run between $54 and $144, with the average price coming out to $99 as the median price.
How does a 4 way OAT coolant test strip work?
4-Way OAT Coolant Test Strips Dip & read test strips to measure Freeze Point/Molybdate levels to determine the level of dilution and pH to determine the level of degradation of the coolant in the system Measures Freeze Point and Molybdate/Nitrite Results in 45 – 75 Seconds
How long should you test es Compleat oat?
REAL™ Serviceability. This can usually be achieved by topping off the cooling system with premixed ES Compleat OAT coolant. The user is responsible for ensuring proper additive levels and coolant pH through the use of test strips and the addition of new coolant if necessary. The recommended test interval is 300,000 miles, 6,000 hours, or 1 year.
How are test strips used to determine coolant quality?
Easy to Use Test Strips to measure for overall coolant quality. Easy to Use Test Strips to Determine if Coolant Make-Up Water Meets OEM, TMC and ASTM Specifications. Determines the Freeze Point Protection for Ethylene Glycol and Propylene Glycol Coolants.
What kind of coolant can you test with acustrip?
The ACU1550 series is suitable for testing OAT-based (IAT – Inorganic Acid Technology, NOAT and HOAT) coolants. More Info . . . These quick and easy strips measure freeze point and pH when used to test conventional glycol-based coolant. Each strip is individually packaged with the color chart printed on the protective foil to allow individual use.
