Coolant, AdBlue and brake fluid: what goes wrong and why

Ready-to-use or concentrate? Read the name

This is the most common confusion on the shelf, and getting it wrong damages engines in both directions.

  • CYCLONFLU products are ready to use. They are already mixed with de-ionised water and go straight into the radiator. CYCLONFLU gives frost protection to −15 °C, CYCLONFLU PLUS to −21 °C, CYCLONFLU LL (G12+) down to −40 °C, and CYCLONFLU LL G13 covers modern aluminium circuits compatible with G12++.
  • RADIATOR products are concentrates. They must be diluted with de-ionised water to the ratio the climate requires. RADIATOR and RADIATOR HD use conventional inhibitor chemistry, RADIATOR LL (G12+) and RADIATOR LL G13 use organic acid technology, and RADIATOR PG SOLAR is a low-toxicity propylene glycol product for solar and other systems where toxicity matters.

Pouring a concentrate in neat is not “extra protection”. Undiluted glycol transfers heat worse than a correct mixture does, so an engine filled with neat concentrate runs hotter than one filled properly — which in an Iraqi summer is exactly the wrong outcome.

In this climate, coolant is not mainly about frost

Nobody in Basra worries about freezing, and that is precisely why coolant gets neglected here. Two of its three jobs matter more locally than frost protection ever will:

  • It raises the boiling point and, with a healthy pressure cap, keeps the system out of localised boiling around the hottest parts of the head.
  • It protects the metal. Modern engines are aluminium, and aluminium corrodes fast in plain water. That corrosion blocks the radiator core, eats the water pump seal and eventually reaches the head gasket.

Topping up with tap water is the single most damaging habit in the market. Tap water brings scale-forming minerals and chlorides straight into an aluminium cooling system, and it dilutes whatever inhibitor is left. Use DISTILLED WATER or BATTERY FLUID, both de-ionised, for topping up and for diluting concentrates — never tap water, and never water from the workshop hose.

Heavy-duty diesel engines need more than car coolant. CYCLONFLUE HD and RADIATOR HD carry organic, borate, silicate and nitrite inhibitors specifically for cavitation erosion protection on wet cylinder liners, which a passenger car coolant does not provide.

Do not mix technologies. Conventional, G12+ organic acid and G13 coolants use different inhibitor chemistry, and mixing them can drop both out of solution and produce a gel that blocks the radiator. When changing type, flush the system.

AdBlue in Iraqi heat

Cyclon AdBlue® is a ready-to-use diesel exhaust fluid, 32.5% urea in ultra-pure water (AUS 32), for Euro IV, V and VI engines with SCR systems. AUS 40 is the 40% marine equivalent for vessels with SCR.

Three things matter locally:

  • It never goes in the fuel tank. AdBlue is injected into the exhaust, not the fuel. Putting it in the diesel tank means draining and flushing the fuel system.
  • Heat shortens its life. Urea solution degrades with sustained high temperature, so shelf life in an Iraqi summer is far shorter than the label figure assumes. Store it shaded, cool and sealed — not on a pallet in the sun behind the workshop.
  • Cleanliness matters. It crystallises on contact with air and is contaminated easily. Use dedicated equipment, keep containers closed, and do not decant it through a funnel that has had oil in it.

Brake fluid and LHM are not interchangeable

BRAKE FLUID 4 is a synthetic DOT 4 fluid, and it is not compatible with mineral-oil-based fluids or with DOT 5 silicone. Brake fluid is hygroscopic — it absorbs water from the air, which lowers its boiling point and corrodes the system from inside. Two years is the usual replacement interval, and humid coastal conditions argue for the shorter end of it rather than the longer.

L.H.M. FLUID is a special mineral hydraulic fluid for Citroën and Peugeot central hydraulic systems using green reservoirs only — brakes, power steering, suspension and shock absorbers. It must never be used in black-reservoir LHS systems, and it is incompatible with DOT brake fluids. Mixing these destroys seals throughout the system.

Frequently asked questions

Should I use ready-to-use coolant or concentrate?

Read the product name. Cyclon CYCLONFLU products are ready to use and go straight into the radiator, already mixed with de-ionised water. Cyclon RADIATOR products are concentrates that must be diluted with de-ionised water. Pouring a concentrate in neat is not extra protection: undiluted glycol transfers heat worse than a correct mixture, so the engine runs hotter than it would if filled properly, which is the opposite of what anyone wants in an Iraqi summer.

Can I top up the radiator with tap water?

No, and it is the most damaging habit in the market. Tap water introduces scale-forming minerals and chlorides directly into an aluminium cooling system and dilutes whatever corrosion inhibitor remains. The corrosion blocks the radiator core, attacks the water pump seal and eventually reaches the head gasket. Use Cyclon DISTILLED WATER or Cyclon BATTERY FLUID, both de-ionised, for topping up and for diluting concentrates. In this climate coolant matters less for frost protection than for raising the boiling point and protecting the metal.

How should AdBlue be stored in hot weather?

Shaded, cool and sealed. Urea solution degrades with sustained high temperature, so real shelf life in an Iraqi summer is considerably shorter than the label figure assumes, and a drum standing in the sun behind the workshop will not keep. It also crystallises on contact with air and is contaminated easily, so use dedicated equipment and keep containers closed. And it is injected into the exhaust, never into the fuel tank: putting AdBlue in the diesel tank means draining and flushing the fuel system.

Can I mix different types or colours of coolant?

No. Conventional coolants, G12+ organic acid coolants and G13 coolants use different inhibitor chemistry, and mixing them can cause both inhibitor packages to drop out of solution and form a gel that blocks the radiator. When changing type, flush the system first. Note also that heavy-duty diesel engines need a coolant with cavitation erosion protection for wet cylinder liners, such as Cyclon CYCLONFLUE HD or RADIATOR HD, which a passenger car coolant does not provide.
