FAQ
WILL THIS FIT MY 2004?
If your truck has the 90 mm early-build pump, yes. Mid-2004.5+ trucks use the 100 mm pump and require MAHLE K31803.
WHAT DOES THIS GASKET SEAL?
It seals the water pump to the engine front cover on the 6.0L Power Stroke to prevent coolant seepage.
IS THIS OEM QUALITY?
Yes. MAHLE builds to OEM form, fit, and function for reliable, long-term sealing.
