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.

Good Fit, 2 pump motors front and back as strong as original in all respects. Read Notes
This came with 2 pump motors on it. One is for a back window washer that I did not have. I did have a wiring harness for both with different type plugs. You must cap the output of the non used motor or it will leak fluid. It comes with a new front wiper hose feed and also comes with a new hose to go to the radiator for the overflow also. It does not come with the 2 rubber feet that slip onto the bottom as a cushion and it does not come with the two plastic pop attachments that hold the 2 bottles to the top frame. This seems as strong and well made as the original. Comes with new caps. The pump on the front of this, facing the front of the vehicle is the front washer pump. I recommend using electrical contact grease. You may want to clean the chassis ground wire connection near the front of where the bottles sit.

Fit my 2005 Astro Van perfectly. Included two new pumps.
Installed and back up and running in under 15 min and under $40. Not many car repairs you can say that about. Included two new pumps, and was plug and play with the front and rear windshield wiper hoses and wiring harnesses. Label your front and back off the old tank before you remove it.
