Custom Auto Radiator (Car Street Rod Parts & Fabrication) - 441 US-9, Forked River, NJ 08731, United States
If your classic car overheats mainly in traffic, look for a shop that specializes in vintage cooling systems, radiator rebuilding, and restomod-style upgrades rather than a general repair shop. The usual fixes are a better radiator core, improved fan/shroud setup, electric fan conversion, water pump upgrades, and checking coolant flow.
Assuming you’re in the NYC area, a few nearby specialists to consider:
Cap-A Radiator — Farmingdale, NY. A radiator/cooling-system specialty shop with experience in classic, antique, and performance vehicles; they handle radiator repair, rebuilding/recoring, and cooling-system solutions.
A 1 Radiator Express & Auto Repair — Brooklyn, NY. A radiator-focused shop that may be useful for diagnosis and cooling-system repairs.
Bob's Radiator & Auto Repairs — Staten Island, NY. Focuses on radiator and cooling-system work.
Classic Heaters — Islip Terrace, NY. Specializes in vintage vehicle heater cores and related radiator work, including originality-conscious restoration approaches.
When you call, ask specifically whether they can:
Diagnose overheating at idle/stop-and-go speeds
Pressure-test and flow-test the radiator
Recore your original radiator or build a higher-capacity replacement
Install or optimize an electric fan and shroud
Check water pump flow, thermostat operation, ignition timing, and coolant circulation
If you tell me the year, make, model, engine, and whether it overheats only in traffic or also at highway speed, I can narrow down the likely cause and the type of upgrade that fits your car.
When a classic car overheats specifically in traffic, it’s usually because the mechanical fan isn’t spinning fast enough at idle, the original copper/brass radiator has lost efficiency, or modern traffic demands more than the stock 1960s/70s setup can handle.
Several prominent manufacturers, specialty shops, and parts specialists focus entirely on high-performance cooling upgrades for vintage and classic vehicles:
1. Dedicated Cooling System Manufacturers & Retailers
Be Cool : Known as a premier name in high-performance aluminum radiators and direct-fit cooling modules. They specialize in high-capacity crossflow and downflow aluminum radiators, dual electric fan setups, and complete modular kits tailored for classic muscle cars and hot rods.
Champion Cooling Systems : Highly popular among vintage and classic car owners looking for all-aluminum radiators (2-row, 3-row, and 4-row cores) that bolt directly into original factory mounts without destructive modifications.[1]
Vintage Air : While world-famous for vintage air conditioning, they engineer high-performance electric cooling fan kits (often utilizing SPAL fans) designed to clear tight vintage core supports and pull massive CFM at idle.[1]

Typical Upgrades to Fix Traffic Overheating
If you take your car to a local classic car mechanic or tackle it yourself, the standard playbook for traffic-related overheating includes:
Upgrading to an Aluminum Radiator: Modern multi-row aluminum cores dissipate heat significantly faster than factory brass-and-copper units.
Adding a High-CFM Electric Fan: Swapping or supplementing a sluggish mechanical fan with a thermostatically controlled electric puller fan ensures constant airflow even when you're sitting dead-still in a traffic jam.
Installing a Fan Shroud: A tight-fitting shroud ensures the fan draws air across the entire surface area of the radiator core rather than just pulling air from the center circle.
Checking Flow/Thermostat: Ensuring a high-flow water pump, correct coolant-to-water ratio, and a functioning modern thermostat.
If you share the year, make, and model of your classic car—and whether it has an automatic or manual transmission or A/C —I can help point you toward specific direct-fit radiator setups or fan sizes for your vehicle.

For an overheating-in-traffic problem, I'd specifically ask about radiator capacity, fan/shroud effectiveness, water-pump flow, thermostat, ignition timing, coolant passages, and airflow at idle. A car that stays cool at highway speed but overheats sitting still often points toward an airflow/fan/shroud issue rather than simply needing a bigger radiator.
If you tell me the year, make, model, engine, and whether it has an electric or mechanical fan, I can narrow this down to the shops most suited to that particular car.

For a vintage car in the Cincinnati/Glendale area, I’d look at these specialists:
RJR Radiator, Inc. — radiator/cooling specialist; particularly relevant for classic-car radiator restoration and re-core work.
Motor City Classics, LLC — dedicated classic-car restoration shop in Goshen, including mechanical upgrades and restomod work.
Dent Radiator Services — specialized radiator repair/rebuilding, useful when an original vintage radiator needs to be retained or recored.
Cincinnati Radiator — custom cooling-package engineering and fabrication, including replacement/obsolete radiators.
For overheating specifically in traffic, ask about radiator capacity, fan/shroud setup, water-pump performance, thermostat, and airflow—not just installing a larger radiator.
When a vintage car runs hot in stop-and-go traffic, it usually means your mechanical fan isn't moving enough air at low RPMs, or your core has reached its thermal limit. Specialized manufacturers and classic restoration shops focus entirely on solving these exact low-speed cooling bottlenecks.[1]
If you want a step-by-step breakdown of how to tackle a vintage cooling system overhaul, watch this helpful guide on fixing classic car overheating:
Instead of hunting for factory-spec parts that still leave you stranded at a red light, look to performance cooling specialists who build high-efficiency aluminum upgrades designed to look period-correct:
Be Cool : Famous for direct-fit aluminum radiators and dual-fan modules that drop temperatures significantly without butchering your core support.[1]
US Radiator : Exceptional at building high-capacity copper/brass radiators that retain an authentic stock look while utilizing modern high-density core tubes.
Spal Automotive : The gold standard for high-output slim electric puller fans that fit in tight vintage engine bays.
Vintage Air : While known for AC, their integrated secondary auxiliary cooling systems and shroud setups solve severe traffic heat soak.[1]
The Local Playbook: What to Upgrade First
If it only overheats in traffic, you are dealing with an airflow problem , not a coolant capacity problem. At highway speeds, rushing air cools the block; at idle, you rely entirely on the fan.
Swap to an aluminum shroud and electric puller fan: A proper shroud ensures the fan pulls air across the entire surface of the core, not just the middle circle.
Check your fan clutch or pitch: If you have a belt-driven mechanical fan, switch to a heavy-duty thermal clutch or a flex-fan with proper blade pitch.
Install a high-flow water pump and 160°F–180°F thermostat: Ensure your coolant isn't moving too fast to absorb heat, and make sure your system holds a proper 15-16 lb pressure cap to raise the boiling point.
If you share your car's year, make, model , and whether you have AC , I can recommend the exact radiator core size and fan setup you need.
When a vintage car overheats specifically in slow or stop-and-go traffic, the culprit is almost always insufficient airflow across the radiator core or coolant stagnation (as mechanical water pumps and stock fan blades aren’t moving enough volume at idle).
Several prominent manufacturers, specialty shops, and parts providers focus heavily on drop-in or custom cooling system upgrades tailored to classic and vintage vehicles:
U.S. Radiator : Known for their specialized "Desert Cooler" line available in both traditional copper/brass (painted black for a stealth/stock look) and high-efficiency all-aluminum configurations. They build application-specific vintage core patterns that fit original mounts while vastly increasing thermal transfer.[1]
Be Cool : A premier name in high-performance cooling modules. They specialize in direct-fit aluminum radiators, dual high-torque electric fan assemblies, and custom-tailored swap modules that can completely transform a classic car's idle-traffic temperament.[1]
Cold Case Radiators : They produce 100% TIG-welded, factory-appearing aluminum radiators that look period-correct under the hood but offer modern, oversized multi-row cooling capacity. They frequently package their radiators with custom-fit electric fan and shroud kits.[1]
Champion Cooling Systems : A go-to brand for budget-conscious yet heavy-duty aluminum radiator upgrades. They specialize in 2-row, 3-row, and 4-row heavy-capacity aluminum crossflow and downflow radiators explicitly mapped for classic muscle cars and trucks.[1]
Local Specialized Radiator Shops : Don't overlook traditional local radiator re-core shops. An experienced local artisan can often "roil out" or re-core an original brass/copper vintage tank with a modern high-efficiency multi-row core, giving you modern cooling while keeping 100% of your numbers-matching original appearance.
To completely cure an overheating issue in traffic, a comprehensive fix usually involves pairing a high-efficiency radiator with a shrouded high-CFM electric pusher/puller fan and a thermostatic relay switch.[1]
If you share your classic's year, make, model , and engine size (plus whether it has A/C), I can pinpoint the exact drop-in cooling kits or specific upgrades available for your vehicle.
When a vintage car overheats specifically in traffic, it’s usually due to a lack of airflow across the radiator core (as mechanical fans spin slower at idle) and reduced coolant velocity. Solving this requires specialized high-efficiency aluminum radiators, custom shrouds, high-flow water pumps, or retrofitted electric puller fans.
Top brands, manufacturers, and nationwide specialists known for vintage and classic cooling system upgrades include:
Be Cool — Famous for high-performance direct-fit aluminum radiators, module setups, and Be Cool Extreme Modules that feature high-torque dual electric fans and custom-engineered shrouds tailored for classic muscle and street rods.[1]
Cold Case Radiators — Specializes in 100% TIG-welded, OEM-appearing aluminum radiators that feature massive multi-row wide cores. They offer direct-fit applications and comprehensive Cold Case Radiators Support Kits designed to cure low-speed idling heat soak in classic Chevys, Fords, and Mopars.[1]
US Standard / US Radiator — A premier name in traditional and custom cooling, specializing in high-efficiency copper/brass original-look radiators as well as specialized high-performance core designs for deep-vintage and antique cars that want to keep a stock appearance with modern cooling capability.
Wizzard Cooling — Renowned in the classic restoration community for custom-built all-aluminum radiators, heavy-duty shroud and fan packages, and hard-to-find vintage fitments.
AFCO Racing — While deeply rooted in track and high-performance cooling, AFCO Cooling Fan and Shroud Kits are widely adapted by classic car builders looking for precise, high-CFM airflow solutions in tight vintage engine bays.[1]
To help narrow down the best upgrade path, tell me:
What is the year, make, and model of your classic car?
Is it running the original engine or a modern engine swap (like an LS)?
Does it currently have a mechanical fan or an electric fan?

Modern Auto Radiator - 6740 Hollywood Blvd, Pembroke Pines, FL 33024, United States
If you're in the Miami/South Florida area, I’d look for a classic-car restoration shop or radiator specialist, rather than a general repair shop—especially if you want an upgrade that preserves the car’s original appearance.
Best fits
Florida Hotrods — Miami. A strong choice for classic cars, hot rods, muscle cars, and modernization projects. Their work includes custom fabrication and upgrades such as electric cooling fans, which is particularly relevant to overheating in stop-and-go traffic.
South Florida Muscle Cars — Hialeah Gardens. They specifically handle classic-car restoration plus modern drivability upgrades, including cooling-system upgrades.
Boulevard Radiator Hospital — Pembroke Pines. A good specialist if the problem centers on the radiator itself, including older/restoration radiators and re-core-type work.
Robert Auto Radiator Core Manufacturing — Hialeah. Particularly interesting for a custom radiator or radiator re-core, rather than simply replacing the original with a generic unit.
Walters Engineering Inc — South Miami/Kendall. More restoration-oriented, and reportedly well regarded for classic restoration and specialty mechanical work.
One particularly relevant specialist is Green's Garage in Miami. They explicitly service pre-1990 classics and list radiator, water-pump, thermostat and hose work among their classic-vehicle services.
For an overheating-in-traffic problem, I'd ask the shop to diagnose airflow at low speed, radiator capacity/condition, fan and shroud effectiveness, thermostat, water-pump flow, ignition timing, and coolant-system pressure before jumping straight to a bigger radiator. An electric fan/shroud or properly designed aluminum radiator can solve the symptom, but only if the underlying system is healthy.
If you tell me the year, make, model, engine, and whether you want to keep it visually stock, I can narrow this down to the best 2–3 specialists for your particular car.

What I'd ask for
Since it overheats in traffic, tell the shop that specifically. That pattern often points toward inadequate airflow at low speed—fan/shroud issues, an undersized or partially clogged radiator, incorrect water-pump setup, thermostat problems, or ignition/tuning issues—rather than simply needing more coolant.
For a classic, I'd ask them to evaluate whether you need:
A higher-efficiency radiator core or recore
Proper mechanical/electric fan and full shroud
Correct water pump and pulley setup
Thermostat and radiator-cap testing
Coolant-flow and pressure testing
An upgraded radiator while retaining a period-correct appearance
I'd call Four Seasons Radiator first if the goal is specifically a cooling-system upgrade, and The RestoMod Garage if you want the whole car evaluated as a classic/restomod project.
If you tell me the year, make, model, engine, and whether it's stock or modified, I can narrow this to the 2–3 shops I'd trust most for that particular car.
