The overflow tank arrived right on time and worked perfectly. It was easy to install. I had a little difficulty getting the cap off but once I got it off everything was fine. This is the exact same part that comes from all of the local parts stores. It had the same name brand and part number. Only difference was it was $30-$35 cheaper.

This was by far best price I could find. Only thing that was not perfect was the cap was so tight the edges cut into plastic neck.

Excellent quality and fit. Changed it in 10 mins. But...just went for an oil change today and the technician found the cap off and laying on top of radiator. Vibration should not be able to loosen this cap. Not impressed with cap quality!

Replaced original factory coolant reservoir which had a design flaw (cap fitting was two-piece with a gasket that failed) and was leaking. New Dorman product much superior - one piece molding means no leaky cap fitting - and interestingly engine runs cooler now that cooling system fully pressurised. Made in Taiwan - good quality plastic and molded-in metal fittings - better than OEM which had a design flaw. Top notch. Easy to install by non-mechanic, tho I did get a mechanic friend to check it out in case I messed up.
