The coolant recovery reservoir collects pressurized coolant from the engine cooling system while the engine is running and provides an easy and accurate way to determine coolant levels. The coolant recovery reservoir is a container that is connected to the engine cooling system via a small hose that allows extra coolant a place to flow when the cooling system is pressurized. When the vehicle cools off some of the coolant in the reservoir flows back into the cooling system. Most are made of clear plastic for viewing of the coolant level and quality of the coolant itself. Many are marked for safe coolant levels when the engine is hot or cold so that a licensed mechanic can inspect when diagnosing a vehicle. Some newer vehicles are equipped with a coolant level sensor to alert the driver to low coolant levels. The coolant recovery reservoir also provides a place to top off the cooling system and refill with fresh coolant when performing a cooling system flush. Our licensed mechanics should perform these procedures because every vehicle requires different attention when flushing, refilling, or bleeding the cooling system.

A cracked or leaking coolant recovery reservoir can lead to engine overheating and electrical | problems. Low coolant level due to a faulty reservoir can cause severe internal engine damage, and the escaping coolant or steam can damage electrical components or other accessories.

The coolant is drained | The old coolant recovery reservoir is removed | The new coolant recovery reservoir is installed | The coolant is refilled and purged of air | The vehicle coolant recovery reservoir is checked for proper operation

If you suspect that your coolant recovery reservoir needs repair, have one of our licensed mechanics inspect the part. There are several components that could cause similar symptoms, and one of our expert mechanics will look over everything and give you a proper diagnosis.

A faulty coolant recovery reservoir can lead to engine damage and other serious problems with a vehicle’s charging system and electrical accessories. Moreover, having to add coolant to a vehicle with a leaky reservoir can get costly over time.
