Engine Coolant Expansion Reservoir
This tank stores and regulates extra coolant as the engine heats and cools. It keeps the system pressurized, stabilizes temperature, and makes it easy to monitor the level. A healthy reservoir helps prevent overheating, protects the water pump and radiator, and keeps your cabin heater working on cold mornings.
Why it’s needed ✅
Coolant expands when hot and contracts when cool. Without a proper overflow bottle, fluid would spill out, air would enter the system, and corrosion could start. This reservoir maintains the right volume, prevents air pockets, and supports consistent engine temperature for long life.
How it works
A small hose links the radiator/degassing line to the tank. As pressure rises, coolant flows in; as it cools, the system draws it back. The cap and molded body are designed to handle pressure and heat cycles. Sight marks on the side show MIN/MAX for quick checks.
If the tank is damaged ⚠️
Cracks, loose caps, or brittle fittings cause leaks, sweet smell, low level warnings, rising temps, weak cabin heat, or gurgling. Running like this risks overheating, warped head, or blown gasket. Replace promptly and bleed the system; use the correct coolant mix.
