Blue Chem Additive - Removes Oil Residues in the Cooling System "pt33336/1"

Blue Chem PT33336-1 is a professional treatment specifically for the removal of contaminating oil residues from the cooling system. It is used when oily traces are present in the radiator circuit — often due to a damaged head gasket, a micro-leak of oil into the cooling circuit, or previous incorrect maintenance — which compromise cooling efficiency and can cause engine damage over time.

Unlike ordinary radiator cleaners that remove limescale and rust, PT33336-1 is specifically formulated to emulsify and remove oil contamination from the cooling circuit, restoring the correct thermal properties of the coolant and protecting circuit materials (aluminium, rubber, plastic) from oil-caused degradation.

• Brand: Blue Chem

Add the product to the cooling circuit. Start the engine and bring it to operating temperature. Allow to circulate for 10–20 minutes with the heater at full blast. Drain completely, flush the circuit with distilled water, and refill with fresh coolant. In cases of severe oil contamination (damaged head gasket), the mechanical issue must be resolved first.
