PAI Coolant Surge Tank Conversion Kit

The PAI Coolant Surge Tank Conversion Kit gives you a complete surge tank and matching components instead of a basic coolant container by itself. It includes the replacement surge tank reservoir, a coolant level sensor, and the necessary adapter fitting to update or convert the overflow/tank setup on Mack CH, R, RB, RD, RW, CL, and CX models with top-tank configurations. This all-in-one kit saves you from ordering separate surge tank parts that may not fit together, which can interrupt service when the existing tank needs full replacement. Surge tanks help manage expansion and air separation in the cooling system, so having the correct reservoir and sensor together improves reliability. With the PAI 3424 surge tank conversion kit, you get the proper reservoir and hardware matched to your Mack cooling layout in a single purchase.
