Review on Front Engine Coolant Reservoir - Dorman 603-487 for Dodge Models by Kevin Williams

Replaced the original factory coolant reservoir that had a design flaw (the cap fitting was a two piece with a defective gasket) and was leaking. Dorman's new product is much better - one piece casting means no leaking caps - and interestingly the engine now runs cooler when the cooling system is at full pressure. MADE IN TAIWAN - HIGH QUALITY PLASTIC AND MOLDED METAL HARDWARE - Better than OEM that had a design flaw. Excellent. Easily installed by a non-mechanic, although I had a mechanic friend to check in case I messed up.
