Toyota 1640136020 — Radiator Cap
Overview
Radiator cap Toyota 1640136020 maintains cooling system pressure at a standard rating of 1.1 bar (108 kPa). The unit incorporates a spring-loaded main pressure relief valve and an internal vacuum return valve. This dual-valve mechanism allows excess coolant expansion into the overflow tank and draws fluid back as the engine cools down. Constructed with a zinc-plated steel body and ethylene propylene diene monomer (EPDM) rubber sealing gaskets, the assembly prevents coolant boiling up to 120 °C. Key dimensions include an outer seal diameter of 45 mm and an overall height of 28 mm. OEM cross-reference numbers include 16401-36020, 16401-20353, 16401-7A020, and 16401-5B630.
