Automotive replacement part designed to restore coolant storage and help keep engine temperature within normal range. Drivers gain reassurance that lubrication is preserved and overheating risk is reduced. Is the HEROFFIX Engine Coolant Reservoir with OE numbers the right fit for your Renault and a sensible DIY choice?
⚡ At a Glance
- • Cooling Performance: Stores excess coolant and helps dissipate heat through the radiator, supporting stable engine temperature.
- • Best for: Owners of Renault Captur I models listed and Renault Clio MK4 (2012-on) needing a direct replacement reservoir.
- • Not ideal for: Vehicles outside the listed Renault Captur I and Clio MK4 applications or non-compatible engine codes.
Radiator surge tank replacement set with OE numbers 217104354R and 217107259R. Stores excess coolant until required and connects to existing radiator hoses to help maintain normal engine operating temperature.
Maintain stable engine temperature - with OE-matched expansion tank and cap
The tank stores surplus coolant and routes it back into the cooling circuit as temperatures fall, while the cap seals the pressurised passages. OE numbers align mounting points and hose connections for the listed Renault models.
Stable operating temperatures reduce the likelihood of overheating during everyday driving. Direct fitment helps avoid hose misalignment and coolant leaks after installation.
Protect internal components - with coolant storage to prevent corrosion and wear
Holding excess coolant prevents repeated loss of fluid that would expose metal parts to corrosion and increased cylinder bore wear. Correctly maintained coolant levels also support the heating system and lubrication.
Reduced corrosion and better lubrication extend engine life, especially on older vehicles. Useful when replacing an ageing or cracked surge tank to preserve internal components.
Straightforward replacement for compatible Renaults - with bolt-on fit and simple hose reconnection
Installation steps include cooling the engine, removing bolts and the old reservoir, allowing remaining coolant to drain, then fitting the new tank and reconnecting hoses and clamps. Final checks confirm correct function.
Competent DIYers can complete the swap with basic tools, avoiding extended downtime. Clear steps help reduce workshop time when professional fitting is preferred.
