Automotive Heater Core & Evaporator Supplier from China | SF Radiator

Importers and distributors who source a car heater core evaporator range from China ask the same questions. Will the parts fit? Will quality stay stable from batch to batch? Can the factory handle custom models and small trial orders?
Jiangyin Shengfei Radiator Co., Ltd (SF Radiator) is a manufacturer based in Qingyang Town, Jiangyin City, Jiangsu Province. We develop, produce and sell aluminum radiators and vehicle air-conditioning products, including automotive heater cores, evaporators and condensers. Our technical team has more than 20 years of experience in the automotive radiator industry.
This guide explains what we make, how we control quality, how customization works, and what to check when you compare suppliers. Use it to prepare a clear inquiry and shorten your sourcing time.

Car Heater Core and Evaporator Manufacturer with 20+ Years of Experience

Our factory covers 3,000 square meters in the Industrial Park of Qingyang Town. We focus on research and development, manufacturing, and sales. This lets us handle standard replacement parts and special projects in one place.

What We Supply

  •  Car A/C Heater Cores for passenger cars, trucks and machinery
  •  Car A/C Evaporator units, including laminated and parallel flow types
  • Parallel flow condensers and tube-fin condensers
  • Automotive air-conditioning systems and water tanks
Many buyers search for a car heater core evaporator as if it were one product. In reality, these are two separate parts. We explain the difference later in this article, and we can quote both in one order to save you freight and paperwork.

Aluminum Heater Cores and Evaporators for Cars, Trucks, Tractors and EVs

Our products cover many vehicle types: cars, pickup trucks, heavy trucks, agricultural machinery and engineering vehicles. Our range includes parts for vehicle series such as GM, Changan, Fukuda and Tesla.
 

Why Aluminum Matters for Buyers

Aluminum is light and transfers heat well. It also suits modern brazing processes, which produce consistent joints across large batches. For distributors, this means stable fit and performance from one shipment to the next.
Some markets still need a classic car heater core for older vehicles. These parts often have unusual sizes and tank shapes. Send us a sample or drawing, and our engineers will review whether we can develop it.

Who Buys From Us

  • Aftermarket importers and wholesalers who stock auto heater core and evaporator ranges
  • Workshop chains and parts retailers that handle heater core replacement jobs
  • OEM and ODM brand owners that need private-label or custom designs
  • Fleet, truck and machinery operators who need dependable heating and cooling parts

Laminated and Parallel Flow Evaporators Built to OEM Standards

The evaporator sits inside the HVAC case and cools the cabin air. Refrigerant absorbs heat as it passes through the evaporator core. A weak or leaking unit means poor cooling and unhappy end customers.
We produce two main designs. A laminated evaporator uses stacked, formed aluminum plates that create refrigerant channels. A parallel flow evaporator uses flat tubes and fins. Both types are common in passenger cars, trucks and work vehicles. We build to the OEM drawing, sample or part number you provide.

Details That Decide Fit

  • Core height, width and thickness
  • Tank design and port positions
  • Inlet and outlet fitting type and size
  • Mounting points, brackets and sealing surfaces
  • Expansion valve connection style, where applicable
If two of these details are wrong, the part will not install. Send full dimensions or a physical sample to avoid delays.

Factory-Direct Automotive Heater Core Wholesale from China

Buying direct from the factory gives you a direct line to the people who build the part. You can ask about materials, test methods and design changes without waiting for a trading company to relay answers.
Buyers often ask about car heater core price first. The price is not a single number, because it depends on the specification and the order. These are the main factors:
  • Core size, number of rows and fin density
  • Tank and tube material
  • Whether the model needs new tooling
  • Order quantity and repeat-order plan
  • Packaging and labeling requirements
Share your target models and yearly volume, and we will prepare a quotation based on those details.

ISO/TS16949-Based Quality Management, Tested for Leaks and Performance

SF Radiator operates in accordance with the ISO/TS16949 international automotive quality management system. We keep absorbing advanced technology and production methods and have introduced high-end equipment over time.
Quality control continues after shipment. We track quality feedback and address process or quality issues raised by customers in a timely way. Please contact us to confirm which certificates and test documents are available for your market.

Advanced Equipment: Nitrogen-Protected Brazing, Automatic Fin Forming and Leak Testing

Heater cores and evaporators work under heat, pressure and vibration. Consistent production equipment is the best defense against early failure. Our key equipment includes:
  • Nitrogen-protecting continuous brazing furnace: joins aluminum parts in a controlled atmosphere for clean, strong joints
  • Automatic fin-forming machines: keep fin shape and spacing consistent from batch to batch
  • Ultrasonic cleaners: remove oil and residue before assembly and brazing
  • Automatic water leak detectors: check sealing before the part ships
A heater core repair cost is mostly labor, because the part often sits behind the dashboard. A leaking replacement part therefore costs your customer twice. Leak testing protects both your reputation and your return rate.

Trusted by Global Buyers for Quality and Reliable Delivery

SF Radiator has built long-term, stable business relationships with partners at home and abroad. We welcome inquiries from importers and distributors in North America, Europe, the Middle East, Asia-Pacific, South America and Africa.
To keep delivery on schedule, we suggest the following:
  • Share your yearly forecast so we can plan production
  • Confirm drawings, samples and packaging before mass production
  • Agree on shipping terms and documents in the quotation

OEM and ODM Heater Core and Evaporator Customization

Our OEM & ODM Radiator service supports buyers who need parts made to their own specifications. This includes brand owners, large distributors and engineering companies. Our team can develop non-standard products when no catalog model fits.

How a Custom Project Usually Works

1. Send your sample, drawing, OEM part number or vehicle model.
2. Our engineers review the design and confirm the specification with you.
3. We prepare the tooling and a sample for approval.
4. We run a trial batch, if you need one.
5. After approval, we move to regular production.
Tell us early if you need private labeling or special packaging. It is easier to plan these at the start than to change them later.

Small-Batch Trial Orders and Non-Standard Product Development

New buyers do not always want to commit to a full container on the first order. We offer small-batch trial production so you can check fit, quality and packaging before you scale up.
Trial orders also help when you add a new vehicle model to your catalog or test a market for a hard-to-find part. Send as much of the following as you can:
  • Vehicle make, model, year and engine type
  • OEM or aftermarket reference numbers
  • Photos from several angles, with key dimensions
  • A physical sample, if available
  • Target quantity for the trial and for the full year

Wholesale Pricing, MOQ and Lead Time for Importers and Distributors

MOQ and lead time depend on the model, the order size and whether tooling already exists. We confirm both in writing in the quotation, so you can compare offers clearly.
For a faster and more accurate quote, include these points in your inquiry:
  • Product type: heater core, evaporator, or both
  • Vehicle models or reference numbers
  • Quantity per model and expected repeat orders
  • Destination country and preferred shipping method
  • Packaging, labeling and document requirements

Free Shipping, 14-Day Returns and After-Sales Support

Our website lists free shipping and a 14-day return and exchange policy. We confirm the exact terms for export orders in the quotation, so there are no surprises on either side.
If a quality issue appears, send photos and batch details. We review the case, find the cause and work with you on a solution. Direct contact with our team also speeds up technical questions about installation and fitment.

What Is the Difference Between a Heater Core and an Evaporator?

A heater core warms the cabin. An evaporator cools it. Both sit in the HVAC system, but they use different working fluids and serve different purposes. The table below shows the key differences for buyers.

Item	Heater Core	Evaporator
Main job	Heats the cabin	Cools and dehumidifies cabin air
Working fluid	Hot engine coolant	Refrigerant from the A/C system
Part of which system	Engine cooling loop and HVAC case	A/C refrigerant circuit and HVAC case
Common failure signs	Sweet coolant smell, foggy windows, weak heat, wet carpet	Weak cooling, musty smell, refrigerant leak
Related SF Radiator range	Car A/C Heater Cores	Laminated and parallel flow evaporators
Key fit details	Core size, tank and pipe positions	Core size, tank design, fitting type and size

Why This Matters for Your Catalog

End customers often search for heater core replacement, replace heater core or how to replace heater core when they notice a sweet smell, foggy windows or a cold cabin. Some try a heater core repair kit or a DIY heater core replacement. However, the job is labor-intensive on many vehicles, so many drivers turn to professional heater core service instead.
This is good news for distributors. Workshops need reliable parts that fit the first time, and they remember suppliers who help them avoid repeat jobs. Stock accurate part numbers and clear fitment data for both heater cores and evaporators.

How to Choose a Reliable Automotive Heater Core and Evaporator Supplier in China

A low quote means little if the part leaks or does not fit. Use this checklist when you compare suppliers.

Check the Factory

  • Does the supplier produce the parts, or only trade them?
  • Can the supplier describe its brazing, cleaning and leak-test process?
  • Which quality management system does the factory follow?

Check the Engineering Support

  • Can the team develop parts from a sample or drawing?
  • Do they offer trial production before bulk orders?
  • Do they answer technical questions clearly and quickly?

Check the Business Terms

  • Are MOQ, lead time, payment and shipping terms written clearly?
  • Is there an after-sales process for quality issues?
  • Does the supplier ask about your market and your end users?
A good supplier asks questions about your project. If a supplier quotes without asking for any vehicle details, treat the quote with caution.

Which Vehicles Do Your Heater Cores and Evaporators Fit?

 
Our range covers cars, pickup trucks, heavy trucks, agricultural machinery and engineering vehicles. We also supply parts for vehicle series such as GM, Changan, Fukuda and Tesla.
Fitment depends on exact dimensions, not only on the vehicle name. To confirm a car heater core evaporator match, send the vehicle make, model and year, plus an OEM number or a clear sample. For electric vehicles and newer models, include as much system detail as you have, because thermal system designs vary by model.
