“My truck runs hot on long grades”
A restricted core, airflow or circulation problem may show under load. We test the radiator and discuss other cooling checks rather than treating heat as proof of a bad core.

What radiator problems can we address?
“My truck radiator leaks at the tanks”
We inspect seams, tanks, supports and core condition before recommending repair, re-tanking or recore.
“I suspect a charge-air cooler leak”
A charge-air cooler needs its own pressure test. We assess leakage separately from the radiator and explain the suitable repair options.
What does big rig & semi truck radiator repair involve?
Most heavy truck radiators come in plugged rather than punctured. Years of scale and additive buildup restrict the tubes, temperatures creep up on grades, and eventually a seam lets go. We clean and rod the core, repair or re-tank as needed, and pressure test to spec before it goes back in the truck.
When a core is past saving, a heavy-duty recore built to the original size gets the truck back in service quickly and often cools better than the worn factory unit. We also test and repair charge-air coolers, which fail quietly and cost you fuel long before they cause a shutdown.

Frequently Asked Questions
Do you work on semi truck radiators?
- Yes. Big rig, dump truck, RV and other heavy-duty radiators are repaired and recored at our D Street shop in Victorville.
Can you test a charge-air cooler?
- We pressure test charge-air coolers separately from the radiator and repair or recommend replacement based on what we find.
Do you handle fleet accounts?
- We do. Call (760) 241-4253 and we will work out turnaround and pricing for multiple units.
How much will this radiator repair cost?
- The condition, construction and work needed determine the cost. We provide a free written estimate after assessing the unit rather than promise a price before seeing the damage.
Where do I bring the radiator?
- Bring it to Johnny's Radiator and Auto Repair at 17033 D St, Victorville, CA 92395. Call (760) 241-4253 to discuss removal and transport before your visit.
What information should I provide when calling?
- Tell us the vehicle or machine make, model, symptoms and any previous repairs. Photos, part numbers and dimensions can help with unusual or hard-to-find assemblies.
Does overheating always mean the radiator needs replacement?
- No. Coolant loss, fans, circulation and engine faults can cause overheating. A radiator test helps establish its condition, but other cooling-system diagnosis may still be needed.
Can I use stop-leak instead of a repair?
- A sealing additive does not restore worn metal or identify the fault and can restrict small passages. Discuss the leak with the shop before adding a product to the system.
