Is Dexcool a Hoat coolant?
Dex is an OAT, Mopar is a HOAT. They don’t gel up when mixed because they’re very similar to begin with, only difference being that the ‘H’ in HOAT is ‘hybrid’, meaning it has added silicate for better corrosion resistance. The only time you may have a problem is mixing a phosphate type green coolant with OAT or HOAT.
Is Prestone coolant A Hoat?
Prestone’s Coolant/Antifreeze is guaranteed to be compatible with all cars, vans or light trucks. Thanks to its unique and patented formula, Prestone Coolant/Antifreeze remains the only coolant on the market that can be mixed with another product within the cooling system without causing damage.
Can you mix Hoat with regular antifreeze?
HOAT coolants, like the IAT coolants, require additives mixed back into the coolant system every 25k miles, or as specified by the engine manufacturer. HOAT coolants formulations are not compatible with OAT coolants because they do contain nitrites. They should not be mixed together.
What color is Hoat antifreeze?
The Colors of Coolant
| TYPE | INHIBITOR TECHNOLOGY | COLOR |

It is impossible for Propylene Glycol solutions to have a Specific Gravity at or above 1.045 at 70 degrees Fahrenheit.
Does GM still use Dexcool?
parkman [OP] Well-Known Member. Does GM still currently use Dexcool in NEW vehicles.
Why is Dexcool bad?
Cooling systems that use Dexcool exhibit more acid buildup and rust in the system when the coolant level gets low and oxygen is allowed to enter the system. The acid eats away at head gaskets and intake gaskets. Rust builds up in the system, inhibiting coolant flow, which causes overheating.
