The package also includes caps and a sensor, making it a near drop-in replacement for routine cooling system repairs.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOE Compatibility:\u003c\/strong\u003e Built to match OE numbers A0525263005 and A0525263007 so it aligns with factory mounting points for a direct fit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplace Part Number:\u003c\/strong\u003e Designed to replace part number 603-5203 which simplifies ordering and confirms it targets the correct assemblies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy Installation:\u003c\/strong\u003e No drilling or cutting required, which saves shop time and reduces the risk of improper installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Package:\u003c\/strong\u003e Ships with the coolant reservoir, two caps and one sensor so you have the basic hardware needed to restore the recovery system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment Range:\u003c\/strong\u003e Compatible with a wide range of Freightliner models from 2008 to 2017, providing flexibility for fleet repairs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis reservoir is aimed at fleet maintenance technicians, owner-operators and DIY mechanics who need a reliable, like-for-like replacement for Freightliner Cascadia, Columbia and Century front models.
