Product Information

Engine Coolant Reservoir Cap

The engine coolant reservoir cap is a critical component of a vehicle's cooling system. It seals the coolant reservoir or expansion tank, which holds excess engine coolant and maintains pressure in the cooling system. The cap is designed to release pressure at a specified level, ensuring that the cooling system operates effectively without excessive pressure buildup.

Engine Coolant Reservoir Cap Failure Symptoms
  • Coolant Leaks: A damaged or improperly sealed cap can lead to coolant leaking from the reservoir, which may be visible under the vehicle or around the reservoir itself
  • Overheating Engine: If the cap fails to maintain the proper pressure, it can cause the engine to overheat due to a drop in the boiling point of the coolant, leading to inadequate cooling
  • Low Coolant Levels: Frequent need to add coolant to the reservoir may indicate a faulty cap that isn’t sealing properly, allowing coolant to escape

About Genuine Porsche

The original parts used by Porsche to build your car are available as replacement parts under the “Genuine Porsche” brand. Manufactured under the direction of Porsche, expect excellent quality and a premium price since these parts are exclusively available through the Porsche Dealership network.

You may not realize this, but the parts that make up your Porsche are not necessarily manufactured by Porsche. No cause for concern, as Porsche designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Porsche for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Porsche parts box and find an OEM branded part inside, simply with the addition of a Porsche logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
