Perfect Replacement Coolant/Windshield Washer Reservoir
Exact Same in every aspect as the original reservoir on my 2003 Chevrolet Astro Van. The reservoir is made of heavy duty plastic. The hose connections, electrical wiring connections, mounting holes up top and mounting nipples at the bottom are an exact match. (Note: remove and reinstall the black rubber sleeves from the old reservoir onto the bottom Mounting nipples of the new reservoir).This reservoir comes with the windshield washer fluid pump as well as the washer fluid pump for the rear hatch window.It was easy to install, 30 minutes total to remove the old reservoir, and install, fill and test this new reservoir.The reservoir arrived on the date promised and came very well packaged.Excellent Product and Price, and a Great Seller.I couldn't be happier.I definitely recommend this product from this seller.

Looks and works fine.
Does what it's designed for.If your vehicle is older, check your window washer check valves. Mine's '02 and they needed replacing.

Perfect fit
Installed on 97 Astro van. Came with 2 pumps (Front and rear) pre-installed on the windshield washer tank which is a plus. I thought I would have to re-use the old ones. No bottom grommets so be sure to remove the ones from the old tank and re-use those. Radiator connector hose was included and of good quality dense rubber. There is no clamp for the radiator connector hose at the radiator cap so expect that. This kit also included some clear replacement tubing, but they were really small diameter, like a fish tank pump would use. Dunno what that was for but definitely not to replace the washer tubing as mine were a bit larger. You can re-use the existing tubing, but I replaced both of mine with some tubing I had in stock.
