Genuine Renault Expansion Tank for Clio 2 RS

Do not risk major engine failure on your sports car. This genuine RENAULT expansion tank is the only certified part capable of maintaining the exact pressure of your cooling circuit. Specially designed for the Renault Clio 2 RS (all phases, including Jean Ragnotti, Clio RS1, RS2, 172, and 182), this coolant reservoir replaces your porous, yellowed, or cracked tank before the irreparable happens.
By neglecting the condition of your current cooling expansion tank, you expose yourself to invisible micro-cracks caused by the high operating temperatures of the F4R engine block. A sudden loss of pressure or a minor leak on trackdays or winding roads can lead to immediate overheating and a blown head gasket. Perform preventive maintenance on your Clio 2 RS with an original manufacturer part to preserve the authenticity and value of your youngtimer.
Note: The matching hoses, clamps, and reservoir caps essential for a complete cooling system overhaul are available at the bottom of this product page.
The Invisible Hazard of a Worn Expansion Tank on Your Renault Clio 2 RS
Over the years and repeated thermal cycles, the plastic of the original coolant expansion tank on your Clio 2 RS ages, becomes opaque, and turns brittle. Keeping a fatigued original reservoir means you lose the ability to visually check your fluid levels instantly. Even more serious, the baked plastic eventually cracks under pressure (which reaches over 1 bar when hot), causing a sudden depressurization of the cooling system.
For a high-performance engine like the 2.0 16V from Renault Sport, an undetected drop in coolant level means instant engine overheating, cylinder head warping, and repairs costing thousands of euros. Replacing your reservoir with this genuine Renault part is an absolute necessity to prevent your sports car from being stranded.
Why the Genuine Renault Cooling Tank is Irreplaceable
The market is flooded with low-cost aftermarket parts, but using a generic component on a sports car like the Clio 172 or Clio 182 carries immense risks. Inferior quality plastics cannot withstand the extreme stresses of trackdays or spirited driving.
Manufacturer-Certified Sealing and Thermal Resistance
This Renault Sport expansion tank meets the strict specifications of the manufacturer. It guarantees:
- Perfect resistance to warping under the extreme heat of the RS engine bay.
- A thread perfectly calibrated for the pressure-rated expansion cap valve, preventing pressure loss.
- Optimal transparency for accurate fluid level checks during your regular mechanical inspections.
Frequently Asked Questions About the Clio 2 RS Coolant Reservoir
When should you replace the expansion tank on a Clio 2 RS Phase 1, Phase 2, or 3?
As soon as the plastic begins to brown, yellow, or if you notice small networks of micro-cracks (crazing) on the sides of the tank. On sports vehicles of this generation, we highly recommend preventive replacement every 10 years or 120,000 km to eliminate any risk of rupture.
Can I install this reservoir myself on my Clio RS?
Yes, replacing this part for customization and mechanical maintenance is straightforward. However, the operation requires a meticulous and complete bleed of your F4R engine block's cooling system to clear out any air pockets. If you lack the proper tools, an incorrect bleed can damage your engine.
