PROBLEM TO BE SOLVED: To provide a polyamide resin composition that can be used suitably for parts used in contact with cooling water in an automobile engine room such as, especially, radiator tank parts and water pump parts, which undergoes less deterioration in material characteristics even under the environment of contacting high temperature engine cooling water and of high temperature engine room, and has excellent calcium chloride resistance, antifreeze resistance, low water absorbing characteristic, product appearance, adherence and weld strength. SOLUTION: The polyamide resin composition for the parts of engine cooling water system includes 100 pts.wt. of a polyamide resin consisting of (A) 50-98 wt.% of nylon 66, (B) 1-30 wt.% of aromatic polyamide resin and (C) 1-20 wt.% of nylon 12, and (D) 5-150 pts.wt. of an inorganic filler.
