FAQS - Helpful Hints "Chem-i-Weld blocked up my radiator." Chem-i-Weld can ONLY cause restrictions in radiators which have a severe build-up of contaminants in the radiator tubes. The first direction for use on the bottle states: “The system MUST BE CLEAN.” Flushing the radiator will eliminate this problem, but the radiator must be cleaned before Chem-i-Weld is used again.
The radiator must not be drained and left dry before flushing – any residual Chem-i-Weld in the system will harden on exposure to air. Boiling the water whilst Chem-i-Weld is being used may block radiator and heater core tubes, and small water galleries in engines.
Directions For Use: Drain and flush the cooling system, including heater. The system must be clean. If the system incorporates a filter or system conditioner, temporarily remove or bypass it. Refill with clean water only.
Leave the system filler cap off, bleed any air out of the system, and run the engine until hotter than normal, but not boiling. This may be done by partially restricting the airflow through the radiator core. Drain sufficient water to add Chem-i-Weld. The water level must be above the radiator core tubes. Do not allow the water to boil.
Shake the Chem-i-Weld bottle well and slowly pour contents into system.
Continue to run the engine at the hotter water temperature with the cap off for approximately 20 minutes. The water level must remain above the radiator core tubes. Do not allow the water to boil. Top up the cooling system and remove the radiator airflow restriction before driving.
Use the vehicle normally until original symptoms are no longer evident. Drain and flush the cooling system, including heater, and fill with clean water. Refit filter/conditioner as necessary. Add corrosion inhibitor, anti-freeze or other additive.
