Subaru 806933010 — Cooling System O-Ring
Overview
Cooling system O-ring Subaru 806933010 seals coolant crossover pipes, thermostat housings, and water pump connections against fluid leakage under variable operating temperatures. Manufactured from heat-resistant EPDM rubber material, this seal resists ethylene glycol coolants, thermal degradation up to +130 °C, and system working pressure up to 2.0 bar. Key dimensions specify an inside diameter of 33.0 mm and a cross-section thickness of 3.1 mm. OEM cross-reference number is 806933010. Exact moulding dimensions maintain uniform compression against metal mating surfaces, creating a tight fluid barrier under continuous engine vibration, rapid pressure changes, and thermal expansion cycles.
Fits Subaru Forester (1997–2018), Impreza (1993–2016), Legacy (1989–2019), Outback (1996–2019), XV (2011–2017), and Tribeca (2006–2014) models equipped with 1.5L, 2.0L, 2.5L, 3.0L, and 3.6L petrol engine variants. Seal replacement is necessary whenever coolant manifold pipes, water pumps, or thermostat assemblies are disassembled during engine overhaul, or if visible coolant leaks appear near pipe joints. Over time, original elastomer seals harden, lose elasticity, and crack from repeated exposure to high temperatures. Installing a new factory-specification O-ring restores full junction tightness without needing supplementary liquid gasket compounds or silicone sealants.
