Our take on the SKP SK603254 Engine Coolant Reservoir - Front

The SKP SK603254 is a front-mounted engine coolant reservoir for a long list of 2007-2018 Mercedes-Benz cars, including the CL, S-Class and C63 AMG. It is a direct-fit replacement tank with a translucent body and clear level markings, so you can check coolant level without opening the cap. It is built from heat-resistant plastic and sold as an OE-style part rather than a factory original, which is the main trade-off: it costs far less than a Mercedes-branded tank but carries no factory warranty and its long-term durability is unproven. It suits owners of older CL and S-Class cars doing their own cooling system repairs.

About the SKP SK603254 Engine Coolant Reservoir - Front

The SKP SK603254 is a replacement engine coolant reservoir for select Mercedes-Benz models with a pressurized cooling system. It stores and contains engine coolant and is meant to replace an original reservoir that has cracked, discolored, or no longer holds pressure.

The body is made from heat-resistant materials and is translucent, with clear level markings. This lets you check the coolant level without removing the tank. It is built to meet or exceed OE specifications for fit and function.

Before installing, confirm the reservoir shape, hose connections, and mounting points against the original part. Inspect the cap, hoses, and nearby cooling components for wear or contamination. After installation, refill the system with the correct coolant type and bleed the air according to factory service procedures.

Questions and answers

Is this a genuine Mercedes-Benz part?
No. It is an SKP aftermarket reservoir made to OE specifications, not a factory Mercedes-Benz part.
Will it fit my 2011 S550?
Yes, the S550 is listed for 2007-2013. Check your model year and whether your car uses the front reservoir before ordering.
Does it come with a cap?
The listing describes the reservoir tank itself. Confirm with the seller whether a cap and level sensor are included before you buy.
How do I know when the coolant level is low?
The translucent body and level markings let you read the coolant level through the tank without removing the cap.
Can I install it myself?
It is a direct-fit replacement, so a DIYer with basic tools can usually swap it. The tank sits in the engine bay and connects to coolant hoses.
Why replace the reservoir instead of repairing it?
Cracks and brittle plastic on old tanks are common, and a replacement tank restores proper level control and pressure sealing.
