Is ethylene glycol safe for aluminum?

The corrosion of aluminum alloy in the presence of ethylene glycol is most likely a result of acidic attack by these acids. … It is not generally recommended to use uninhibited ethylene glycols for heat transfer applications. If uninhibited ethylene glycol is used, it must be used with caution and carefully monitored.

Does coolant corrode aluminum?

Coolant pH become aggressive to aluminum and solder in a cooling system. Maintaining optimum pH in a coolant is a critical function of a quality coolant additive (SCA). It is important to use coolant additive package containing a pH buffer to insure the optimum pH range of the coolant.

Is Dexcool still a problem?

GM still uses Dex-Cool coolant and there is no longer a problem with gasket coolant interaction. So contrary to the ranting, DexCool IS the recommended coolant for GM engine.

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.

Is Dex cool better than antifreeze?
