MAHLE Victor Reinz (MAHLE Original gasket line) C33755. OE-quality sealing component/set for diesel engine service.
Need a reliable gasket to properly seal your coolant bypass connection and prevent leaks in the cooling system? The MAHLE Coolant Water Bypass Gasket is an OE-style replacement designed to seal the coolant water bypass connection and maintain proper coolant flow within the engine’s cooling system. Over time, heat cycles and coolant exposure can cause the original gasket to degrade, leading to seepage or pressure loss in the cooling circuit. Replacing it with a precision-engineered MAHLE gasket restores a dependable seal, helping prevent coolant leaks while ensuring consistent cooling system performance. This gasket is commonly used on GM 6.6L Duramax engines, making it an ideal replacement during cooling system service or component replacement. Manufactured to meet or exceed original equipment specifications, the MAHLE C33755 is built with durable gasket materials that withstand coolant
Notes: Follow MAHLE torque/installation specs. Replace one-time-use fasteners as required. Preserve factory emissions equipment; this listing is not an EGR delete or block-off kit.
