AC Battery Coolant Chiller

Tesla Model S Battery Coolant A/C Chiller (HVB) — 1007476-00-E

Early Tesla Model S vehicles use a dedicated battery coolant chiller to pull heat out of the high-voltage battery loop. This plate-style heat exchanger lives in the A/C circuit and uses the R134a refrigerant path to chill the glycol coolant that circulates through the battery pack, drive units, and power electronics.

The unit offered here is the correct HVB Battery Coolant Chiller assembly for Model S Feb 2012–Mar 2016, Tesla P/N 1007476-00-E. It includes the chiller body and TXV for the battery loop (typically supplied without the electric solenoid valve), and is a direct replacement for vehicles experiencing
battery over-temperature warnings, limited fast-charge rates, or refrigerant/coolant cross-leaks at the chiller.

• OEM-spec HVB chiller — plate heat exchanger and TXV assembly designed specifically for the Model S battery loop.
• Maintains battery temperature — uses the A/C system to cool pack coolant during Supercharging, spirited driving, and hot-weather use.
• Correct 2012–2016 fitment — direct bolt-in for pre-facelift Model S with R134a refrigerant; works on RWD and Dual Motor variants.
• Common failure remedy — ideal when the original unit is leaking, internally restricted, or contaminated after compressor failure.
• Drop-in assembly — interfaces with factory A/C lines and coolant hoses; no harness modifications required.
