The Coolant Level Sensor with OEM number 3820015LD291 is designed for JAC N35, N56, N75, N80, N120, and N350 trucks. It monitors the coolant level in the expansion tank or radiator and triggers a warning light when the level falls below a safe threshold, helping prevent overheating caused by insufficient coolant.
This sensor operates on a float or electrode principle to detect whether coolant is present at the sensing point. When the level drops, the sensor signal changes and the ECU or instrument cluster illuminates a low-coolant warning. A failed sensor — whether due to a stuck float, corroded electrode, or damaged connector — can cause false warnings or fail to warn when the level is actually low.
- Confirmed Fitment: The JAC official dealer in Blagoveshchensk lists 3820015LD291 for N35, N56, N75, N80, N120, and N350. Tonnazh lists it for N56.
- Confirmed Manufacturer & Weight: JAC manufacturer; 0.1 kg weight — per Autoopt (АвтоАльянс) catalog.
- Confirmed Brand & Warranty: IZUMI aftermarket brand available; 3-month warranty offered.
- Confirmed Packaging & Lead Time: Neutral box, color box, or custom branded packaging; delivery 15–20 days after payment; small orders accepted.
- Caution Product Name Conflict: Russian parts catalogs (Autoopt, Tonnazh, JAC Blagoveshchensk dealer) consistently label this part as “Датчик уровня охлаждающей жидкости” (Coolant Level Sensor). IZUMI multi-language pages label the same number as “Water Temperature Switch” (水温开关). These are different functions — confirm with the seller which function your vehicle requires before ordering.
- Caution Technical Data Gap: Connector type, thread size (if applicable), and electrical resistance values are not disclosed in available search results. Measure the original sensor if precise matching is critical.
- Low-coolant warning light illuminated when the level is actually normal (false warning)
- No warning when coolant level is low (failed sensor)
- Coolant residue or corrosion at the sensor connector
- Visible damage to the sensor body or float
- Intermittent warning light behavior

Important Fitment Notes:
HDA-008 / MC828264 are aftermarket cross-reference numbers, primarily appearing in Mitsubishi Fuso brake booster catalogs. This product is primarily oriented toward ISUZU FSR 6HE1 fitment, while the above numbers are listed for customer cross-comparison.
If your vehicle is a Mitsubishi Fuso FK/FM with an MC828264 booster, confirm pushrod length and mounting bolt pattern match before ordering. “Short” and “long” pushrod variants exist within the MC828264 family.
Always provide the VIN/chassis number for verification. Do not rely solely on cross-reference numbers.

| Visual defects (cracks, corrosion) | 100% visual inspection |
| Weight check | 0.1 kg reference |
| Packaging integrity | Carton condition check per shipment |
Important: Allow the engine to cool completely before removing the coolant level sensor. Hot coolant can cause severe burns. Use new O-rings or gaskets if supplied. Do not overtighten plastic-threaded sensors.
- Ensure the engine is completely cool. Place a drain pan below the sensor location.
- Disconnect the electrical connector from the sensor.
- Remove the sensor (threaded or retained by a clip, depending on design). Extract carefully.
- Clean the mounting area. Inspect the expansion tank for debris or damage.
- Install the new sensor with a new O-ring/gasket if provided. Torque to specification (confirm in manual — typically low torque for plastic sensors).
- Reconnect the connector until it clicks.
- Refill coolant to the correct level. Start the engine and check for leaks.
- Verify the low-coolant warning light functions correctly (ignition on, engine off, if applicable).
- Inspect the sensor connector and mounting area for corrosion during coolant service.
- Replace if warning light behavior is inconsistent and wiring is confirmed good.
- Check coolant level visually at every oil change.
