What Water Pump Fits a 2016 Lexus RX?
What decides water pump fit on the 2016 Lexus RX, where to find your VIN, and how to replace it.
VinSnap does not have a verified water pump part number for the 2016 Lexus RX yet. Which water pump fits depends on the engine code and how the pump is driven (timing belt, timing chain or accessory belt), so compare those on the part you are replacing. The 2016 RX was built with 10 engine variants (from 2.0 L to 3.5 L), so the right water pump depends on which one yours has. The 17-character VIN is on the driver-side dashboard at the base of the windshield and on the sticker in the driver’s door jamb; it identifies the exact engine and trim.

Water Pump: what it does & when to replace it
The water pump circulates coolant through the engine and radiator to keep temperatures in check. Failure signs include coolant leaking from the pump weep hole, a whining or grinding bearing noise, overheating, or coolant pooling at the front of the engine. On many engines the pump is driven by the timing belt, so it is commonly replaced together with the timing belt to save labor. This is an advanced DIY or shop job — access is often deep in the engine and incorrect coolant bleeding can cause overheating.
