High Desert heat is brutal on cooling systems. A radiator that is even slightly restricted will hold temperature fine on a cool morning and then spike on the I-15 grade in August. We pressure test the system, check the fan and thermostat operation, and inspect the core before we quote anything.

Because we still do radiator work in-house, we can often repair or recore a unit for less than the cost of a new assembly — and turn it around faster than ordering one in. Every repair is backed by our 1-year warranty.

Every type of radiator, repaired in Victorville

Copper, brass, aluminum, mixed-metal or a full recore — it all gets done in-house at our D Street shop. No shipping your radiator down the hill and waiting.

Copper Radiator Repair

Copper cores are worth saving, and we treat them that way. Johnny has been rodding out, re-soldering and rebuilding copper radiators in Victorville for more than thirty years, using solder and core stock chosen for the job instead of whatever is cheapest on the shelf.

Whether the unit came out of a daily driver, a show car or a piece of shop equipment, the goal is the same: full flow through every tube, no seeps at the seams, and the heat transfer copper is known for.

Brass Radiator Repair

Brass tanks crack, seams open up and filler necks fatigue — all repairable on the bench rather than replaced. We clean the unit, pressure test it, find every leak, then repair and re-seal it so it holds like it did new.

Brass and copper assemblies stand up well to corrosion and are easy to service again down the road, which is exactly why owners of older vehicles keep them.

Aluminum Radiator Repair

Nearly every late-model car, truck and SUV runs an aluminum core, usually with crimped-on plastic end tanks. When a tank splits, a gasket weeps or the neck breaks, re-tanking is frequently faster and cheaper than a whole new assembly.

We also handle all-aluminum performance and crossflow radiators. Every job starts with a pressure test so you know exactly what failed, and finishes with another one so you know it is fixed.

Metal & Mixed-Metal Tank Radiator Repair

Plenty of radiators mix metals — a copper core with brass tanks, or an aluminum core with steel mounts. Those combinations take a different repair approach, and guessing wrong ruins the part.

We identify the materials first, then repair with the right technique so the fix lasts. Industrial, agricultural, RV and heavy-duty units are welcome alongside cars and light trucks.

Radiator Recore & Rebuild

When a core is too far gone to patch, a recore keeps your original tanks and mounting hardware and puts a fresh core between them. For older and hard-to-find radiators that is often the only way to get the vehicle back on the road.

It is also a chance to upgrade: adding rows gives you more cooling capacity than the factory unit had — useful on the I-15 grade in August.

Commercial & Construction Equipment Radiator Repair

Downtime on a jobsite costs more than the repair. We rebuild, rod out and recore radiators, oil coolers and charge-air coolers for construction equipment across the High Desert — forklifts, telehandlers, dozers, excavators, skid steers, backhoes, loaders, generators and water trucks.

Pull the unit and bring it to the D Street shop and we will test it, tell you what it needs, and in most cases have it back to you in a day or two instead of waiting weeks on a factory part.

Big Rig & Semi Truck Radiator Repair

Heavy-duty truck radiators take a beating pulling the Cajon Pass in summer. We repair, recore and rebuild big rig radiators, charge-air coolers and oil coolers for owner-operators and fleets right here in Victorville.

Large copper/brass and aluminum truck cores are our everyday work — no shipping the radiator down the hill and waiting a week to get rolling again.

Frequently Asked Questions

Do you repair copper and brass radiators?
Yes — copper and brass work is our specialty. We rod out, re-solder, re-tank and recore copper/brass cores for classics, hot rods, tractors and heavy equipment right here in Victorville.
Can aluminum radiators be repaired?
Many can. Plastic-tank aluminum radiators can often be re-tanked or resealed, and all-aluminum cores can be repaired depending on where the damage is. We pressure test first and give you a straight answer.
Can a cracked or leaking radiator be repaired instead of replaced?
Often, yes. Plastic-tank radiators can frequently be resealed or re-tanked, and copper/brass radiators can be rodded out or recored. We inspect and pressure test first, then tell you honestly whether repair or replacement is the better value.
How long does radiator service take?
Most repairs and recores are completed in one to two business days. Drive-in pressure testing and diagnosis usually happens the same day.
Do you service classic and heavy-duty radiators?
Yes. We work on classic car radiators, trucks, RVs and industrial units in addition to modern cars and SUVs.
My car overheats only in traffic — is it the radiator?
Not always. Overheating at idle often points to a failing cooling fan, fan clutch, thermostat or water pump. We diagnose the whole cooling system before recommending a radiator.

Overheating? Bring it in.
