Whether leaking or damaged, our skilled technicians restore, old corroded radiators and radiator tanks to like-new condition--inside and out. Trust Diamond Radiator Ltd. for dependable, professional repairs throughout Langley, the Lower Mainland, and the Fraser Valley. As your one-stop shop for radiator repairs, we specialize in industrial and heavy-duty radiators and cooling systems. From forklifts and heavy trucks to mining and construction equipment to buses, we service automotive and industrial radiators of all types and sizes. No job is too big or too small, and we pride ourselves on fast turnaround times that reduce downtime and keep your equipment working.

Our shop is dedicated to heavy-duty radiator repair, supporting semi-trucks, construction machinery, agricultural equipment, and industrial cooling systems. Our services include expert leak detection and repair, re-coring, aluminum and steel welding, and custom radiator manufacturing—solutions standard automotive shops aren’t equipped to handle.

What Heavy Duty Equipment Radiator Repair Includes?

Repair & Re-coring: Fixing leaks and replacing internal cores for large industrial and automotive radiators.
Welding: Expertise in aluminum, brass, and steel welding for tanks, connections and components.
Custom Builds: Manufacturing new radiators from scratch for unique or classic heavy equipment.
- When original parts are no longer available, we can re-create components using existing OEM designs--often improving cooling performance and durability. Cooling options include increased core thickness, larger 3/4" tubes, or low flow tube designs for enhanced heat transfer.
- For harsh industrial environments such as mining, forestry, and farming we offer durable material options including copper, brass and steel fins.
- Specialized fin configurations improve airflow and simplify maintenance, with wider spaced fins and in-line tube designs that make cleaning dust, dirt, sawdust, and agricultural debris faster and more effective.
Oil & Air coolers: Servicing and repairing these essential heat exchangers for machinery.
Fuel Tank Services: Flushing. cleaning, repairing, and coating steel and aluminum tanks.

Why Choose a Specialist?

Scale & Complexity: Heavy-duty systems are larger, more robust, and use different materials than standard vehicles.
Specialized Parts: We stock or can source cores and components for mining, construction, heavy industry and transport.
Expertise: Technicians are trained for industrial applications, not just cars.

Maintenance & Simple Fixes.

To get more cooling from your radiator, keep it's fins clean and unobstructed, ensure proper airflow with a fan shroud and electric fan, use high-quality coolant, and maintain your system by flushing it and check the thermostat and water pump, or upgrade to a larger, high-performance radiator for significant improvement.

Clean Radiator: Remove debris (bugs, leaves, dirt) from fins using low-pressure water or compressed air, & straighten bent fins with a fintool.
Install a Fan Shroud: Directs air through the core, significantly improving efficiency, especially at low speeds.
Check Airflow: Ensure nothing blocks the grill and that area around the radiator is sealed so air can't escape easily.
Use Quality Coolant: A premium, coolant / antifreeze mix offers better corrosion protection and heat transfer.
Purge the Air: Remove air pockets from the system by elevating the front of the car and running engine with heat on high to cycle the coolant through the heater core.
Inspect Belts & Hoses: Ensure belts aren't slipping and hoses aren't collapsed for proper water pump and coolant flow.
Upgrade the Radiator Cap: A higher-pressure cap raises the boiling point of the coolant.
