This OEM-style front cooling radiator (Tesla PN family 1494175-00-A / 1494175-00-B) is the primary heat exchanger for the low-temperature coolant loop in the Tesla Model Y. Mounted behind the front bumper, it removes heat from coolant circulating through the high-voltage battery pack, drive unit, and power electronics. A damaged or restricted radiator can cause thermal warnings, reduced performance, slower DC fast charging, or derated power in hot conditions.
| Technical Specifications & Fitment | |
|---|---|
| Tesla OEM PN (radiator) | 1494175-00-A / 1494175-00-B (cooling radiator assembly); commonly cross-referenced to 149417500B and 1607811-00-B in aftermarket catalogs. |
| Vehicle fitment | Tesla Model Y 2020–2024 (all trims) front low-temperature cooling radiator. Also used on many late Tesla Model 3 vehicles that share the same front cooling module; verify by VIN. |
| Construction | Aluminum tube-and-fin core with molded plastic end tanks, 1-row cross-flow design for efficient cooling with low mass and pressure drop. |
| Core dimensions (approx.) | ~23.35″ wide × 14.81″ tall × 1.03″ thick core (single row), compatible with OEM 149417500B radiator applications. |
| Inlet / outlet size | Designed for factory Model Y low-temperature coolant hoses; uses OEM-style quick-connect fittings and hose diameters. |
| Location | Front of vehicle, behind the bumper cover, clipped into the cooling fan and shroud assembly as part of the front cooling module. |
| Included | Radiator assembly (core and tanks) only. Does not include fan/shroud module, active grille shutter, hoses, sensors, or mounting frame unless otherwise specified in product options. |
| Installation notes | Requires draining the low-temperature coolant loop, removing front under-trays and bumper cover, detaching the cooling fan module, and performing a vacuum-fill / bleed upon reassembly. Always follow current Tesla service procedures. |
Replacing the front radiator on a Model Y involves more than just swapping a core. The vehicle should be placed in Service Mode, front aero panels and the bumper cover must be removed, and the coolant system should be vacuum-filled to avoid air pockets that can cause noise or thermal faults. We recommend having this work performed by a Tesla-experienced EV shop such as Gruber Motors or a technician familiar with Model Y thermal systems.
Maintenance tip: Whenever the front radiator is replaced, inspect and clean the condenser, active grille shutter, and lower air deflectors. Adding or repairing stone-guards in front of the cooling pack and using only Tesla-approved coolant mixed with deionized or distilled water helps maximize radiator life and keep thermal performance consistent.
