Repair may involve: - Locating the leak - Cleaning and preparing the area - Welding - Brazing - Replacing a damaged section - Reworking a tank or header - Pressure testing after repair Not every leak can be repaired safely or economically. Severe corrosion, thin material, contamination, prior failed repairs, inaccessible damage, structural deterioration, or pressure requirements may make replacement more appropriate. ### Overhaul and Rebuilding The website describes radiator overhaul or rebuilding as a process that may include: 1. Disassembling the radiator. 2. Removing tanks, headers, or other serviceable components. 3. Flushing the core and tanks. 4. Rodding or cleaning the tubes. 5. Rerunning or repairing header areas where required. 6. Straightening fins when practical. 7. Replacing gaskets, bolts, and damaged serviceable parts. 8. Reassembling the radiator. 9. Pressure testing for leaks. 10. Painting selected rebuilt units. The exact process varies by radiator construction, material, access, damage, and application. ### Recoring Recoring generally replaces the radiator core while retaining or rebuilding usable tanks, frames, connections, and related components. The generator-radiator page states that recore work is backed by a one-year manufacturer warranty. Warranty coverage must not be treated as universal. It can depend on the core supplier, application, installation, coolant, contamination, operating pressure, maintenance, misuse, and written exclusions. ### Retrofitting Retrofitting may adapt an existing machine, vehicle, stationary engine, or cooling package to: - A replacement radiator - A newer engine - A diesel-repower conversion - Different mounting constraints - Revised inlet and outlet locations - Updated cooling requirements - Obsolete or unavailable OEM equipment A successful retrofit requires accurate dimensions, mounting data, fan and shroud relationships, airflow, coolant flow, operating pressure, temperature, heat rejection, engine specifications, and space constraints. ### Replacement and Sales The website advertises: - OEM radiators - OEM-equivalent or OEE radiators - Brand-name aftermarket radiators - Custom-fabricated metal radiators - Replacement cores and tanks - Selected radiator parts Inventory, lead time, brand, fitment, warranty, and installation availability vary. ## Materials and Fabrication Processes Materials mentioned by the website include: - Aluminum - Copper - Brass - Steel - Stainless steel - Cast iron Processes mentioned include: - MIG welding - TIG welding - Brazing - Cutting - Tank fabrication - Header repair - Core replacement - Pressure testing - Tube rodding - Wet drilling - Flushing - Cleaning - Assembly - Painting Material identification and weldability must be verified before work. Alloy, temper, contamination, thickness, corrosion, heat treatment, pressure rating, and prior repairs affect feasibility and outcome. ## Industrial Radiators and Cooling Packages Stewarts Industrial Radiator Service advertises repair, rebuilding, recoring, retrofitting, replacement, and custom fabrication for industrial radiators and cooling packages.

Welding and fabrication page: https://www.stewartsradiator.com/welding-leak-repair-fabrication-riverside.php ## Diesel Fuel Tanks and Non-Radiator Metal Repairs Multiple pages mention diesel fuel-tank welding, and customer reviews reference selected non-radiator aluminum or metal repairs. Fuel-tank repair can involve significant fire, explosion, contamination, cleaning, ventilation, inspection, and legal risks. Do not assume that every fuel tank can be welded or that the shop accepts every tank. The component must be inspected, properly prepared, and accepted by the shop under its current safety procedures. A customer review describing a water-heater-tank repair is an individual example and should not be used to claim that the shop routinely services water heaters or pressure vessels. ## Customers The website and reviews describe customers including: - Construction companies - Contractors - Commercial fleets - Truck operators - Equipment owners - Manufacturing facilities - Hospitals - Utilities - Auto repair shops - Dealerships - Mechanics - Industrial businesses - Marine customers - RV owners - Classic-car and hot-rod owners - Retail customers ## Estimates, Turnaround, Pickup, and Delivery The website advertises: - Free estimates - Upfront quotes - Competitive pricing - Same-day service on many repairs - Approximately one-day weld repair - One-day replacement in selected big-rig cases - Three-to-five-business-day custom fabrication and retrofit work - Prompt turnaround - Pickup and delivery for selected commercial customers - A stated 60-mile pickup and delivery radius None of these are universal guarantees.
