Changan CS35 AT Radiator – Part No.: S101030-0301

Let’s keep it simple—this isn’t just a “cooling part” for your Changan CS35. It’s a specialized radiator for the car’s automatic transmission (AT)—the part that stops your AT from overheating when you drive. Made of lightweight, heat-conductive aluminum alloy (great for quickly moving heat away), it has thin cooling fins (to boost heat dissipation) and sealed oil ports (for AT fluid flow). Mounted in the CS35’s engine bay—usually near the main engine radiator—it connects directly to the AT via hoses, circulating hot transmission fluid through its core to cool it down. Think of it as the “AT’s ‘cooling helper’”: without it, your CS35’s AT would get too hot, leading to rough shifts, worn parts, or even total transmission failure.

This AT radiator is exclusive to Changan CS35—always check your vehicle’s VIN to confirm fitment! It’s tailored to the CS35’s AT specs: its core size matches the AT’s fluid flow rate (no under-cooling or slow circulation), its oil ports fit the CS35’s original AT hoses (no leaks from mismatched connections), and its cooling capacity handles the AT’s heat output (even in stop-and-go traffic or hot weather). Grab a generic AT radiator or one for other models? You’ll run into trouble: wrong port size (causes fluid leaks), too-small core (can’t cool the AT enough), or incompatible material (corrodes and clogs the AT fluid lines).

Core Jobs: Cool AT Fluid & Protect the Transmission

As a must-have for the Changan CS35’s AT system, it does three key jobs to keep your drive smooth and reliable:

Lower AT fluid temperature: When you drive, the CS35’s AT creates heat (from gears shifting and fluid friction). This radiator pulls hot AT fluid into its core, where the aluminum fins and airflow (from the car moving or the cooling fan) draw heat away. The cooled fluid then flows back to the AT—keeping temps between 80–110°C (the safe range for ATs).

Maintain AT performance: Overheated AT fluid gets thick and loses its ability to lubricate gears or transfer power. The radiator keeps fluid thin and effective, so your CS35 shifts smoothly (no jerks or delays) and accelerates consistently—even on long drives.

Extend AT lifespan: Hot fluid wears down AT parts (like clutches and seals) fast. By keeping temps in check, the radiator prevents premature wear, helping the CS35’s AT last for years (instead of failing early from overheating).

This S101030-0301 AT radiator only fits Changan CS35—wrong fit means AT damage:

Fits These: All Changan CS35 variants with automatic transmission (matches AT fluid flow, hose size, and engine bay mounting points—confirm with VIN).

Won’t Fit These:

Changan CS35 with manual transmission (MT): MTs don’t use AT fluid or need this radiator (no hoses to connect to).

Other Changan models: Like CS55, UNI-T, or Eado—different AT designs, fluid flow rates, and engine bay space (radiator won’t fit or cool properly).

Non-Changan vehicles: Even if visually similar, their AT specs (fluid type, port size) don’t match (risks clogging the CS35’s AT or leaking fluid).

CS35 with modified AT: Aftermarket AT kits (e.g., performance ATs) have higher heat output—original radiator can’t keep up (causes overheating).

 Installation & Upkeep (Pros Only—AT Safety Is Key!)

Installation: Must Be Done by Certified Technicians

Replacing this radiator involves handling AT fluid (a critical, messy job)—DIY risks leaks or AT damage:

Prep: Techs drain the CS35’s AT fluid (to avoid spills), disconnect the AT hoses from the old radiator, and remove the radiator’s mounting bolts.

Remove old radiator: They pull out the old unit, check the AT hoses for cracks (replace if worn), and flush the AT fluid lines (to remove debris that could clog the new radiator).

Install new radiator: They bolt S101030-0301 to the CS35’s engine bay (align with mounting brackets), reconnect the AT hoses (tighten to Changan’s torque specs—too loose leaks, too tight breaks hoses), and refill the AT with Changan-approved fluid.

Test: They start the CS35, let the engine run to circulate AT fluid, and check for leaks (around ports and hoses). They also monitor AT temp while driving—ensuring it stays in the safe range.

Maintenance: Easy Checks to Keep It Working

Check AT fluid level annually: Low AT fluid means the radiator isn’t circulating enough fluid (causes overheating)—have techs top up with Changan’s recommended AT fluid (don’t use generic fluid!).

Clean the cooling fins every 6 months: Dust, bugs, or road debris (like leaves) clog the fins—use compressed air or a soft brush to clear them (clogged fins can’t cool the fluid).

Inspect for leaks monthly: Look under the CS35 for red/brown fluid (AT fluid) near the radiator—leaks mean worn port gaskets (fix immediately to avoid AT damage).

Replace after 8–10 years: Even with good upkeep, aluminum cores corrode over time—old radiators lose cooling power (swap it before it causes AT overheating).

Summary: Changan CS35 AT Radiator (S101030-0301)

Exclusive to Changan CS35 with automatic transmission (AT) (confirm VIN for fitment), this radiator is made of lightweight, heat-conductive aluminum alloy—featuring thin cooling fins and sealed oil ports. Mounted in the engine bay near the main radiator, it connects to the AT via hoses to circulate and cool AT fluid.

Key roles: Lower AT fluid temperature (maintaining 80–110°C, the safe range), ensure smooth shifts and consistent acceleration by keeping fluid effective, and extend AT lifespan by preventing overheating-related wear.

It fits all CS35 AT variants but not CS35 manual models, other Changan vehicles (e.g., CS55, UNI-T), non-Changan cars, or CS35 with modified AT.

Professional installation is required (involves draining AT fluid and flushing lines). Maintenance: Annual AT fluid checks, 6-month cooling fin cleaning, monthly leak inspections, and replacement every 8–10 years. Original parts guarantee proper fit and reliable cooling.
