What Are Peugeot 308 Coolant Reservoirs?
The coolant reservoir — also called the expansion tank — is the plastic bottle that holds overflow coolant as your Peugeot's engine heats and cools. 206, 207, 307, 308, 2008, 3008 and 408 all suffer hairline cracks in the tank neck or filler cap seat, especially on high-mileage SA cars.

Common Questions About Peugeot 308 Coolant Reservoirs
How much does a Peugeot coolant reservoir cost?
SA retail is friendly — Modern Auto Parts stocks 206 expansion tanks, and BobShop lists an aftermarket tank at R707 fitting 206/207/307/308/408/3008/301/2008. Labour is one hour. Send your VIN for the exact part-number match.
What are the symptoms of a cracked coolant reservoir?
Slowly dropping coolant level, a sweet coolant smell after driving, and white scale deposits around the tank seams. On 206 and 207 models the crack typically starts at the filler neck — look for a damp patch under pressure with the cap on.
Why does my Peugeot keep losing coolant?
A cracked expansion tank is the most common cause across 206, 207 and 308 — well-documented on Peugeot Forums. Other suspects are a perished radiator cap, a weeping hose clamp or a head-gasket leak. Pressure-test the system to locate it.
Can I drive my Peugeot with a leaking coolant reservoir?
Only briefly and only with the level topped up. A leaking tank loses pressure, which drops the boiling point of the coolant and causes overheating. Overheating a 1.6 THP or 2.0 HDi can warp the head — far more expensive to fix than a new tank.
Where can I buy a Peugeot expansion tank in South Africa?
We source reservoirs nationally through Mini and French Citi, Modern Auto Parts and BobShop. 206/207/308 tanks are common stock; 3008 and 408 units need ordering. Send us your VIN for a same-day quote.
