[Chevrolet Astro: 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005] - [Gmc Safari: 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005]. Review: Fit Astro Van - Very good Review: 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. ## Features - Direct replacement - this engine coolant reservoir matches the fit and function of the original part - Ideal solution - engineered for a seamless installation - Durable construction - manufactured from quality materials to withstand underhood heat and vibration - Trustworthy design - backed by 100 years of automotive aftermarket experience - Ensure fit - to make sure this part fits your exact vehicle, input your make, model and trim level into the garage tool ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01KKFP27K | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #57,675 in Automotive ( See Top 100 in Automotive ) #85 in Car Styling Reservoirs | | Brand | Dorman | | Brand Name | Dorman | | Capacity | 1.5 liters | | Compatible with Vehicle Type | Van | | Customer Reviews | 4.7 out of 5 stars 344 Reviews | | Exterior Finish | Machined | | Exterior finish | Machined | | Fit Type | Vehicle Specific | | Fuel Type | Diesel | | Global Trade Identification Number | 00019495433002 | | Included Components | Dorman 603-039: Dual Coolant / Windshield Washer Fluid Reservoir | | Item Dimensions | 29.1 x 18.5 x 48.5 centimeters | | Item Type Name | Dorman 603-039: Dual Coolant / Windshield Washer Fluid Reservoir | | Item Weight | 1.71 kg | | Item dimensions L x W x H | 29.1 x 18.5 x 48.5 centimeters | | Item weight | 1.71 kg | | Manufacturer | Dorman Products | | Manufacturer Part Number | 603-039 | | Material | Aluminum | | Material Type | Aluminum | | Model Number | 603-039 | | Number of Items | 1 | | OEM Equivalent Part Number | 12363310; 22677855 | | Product Grade | Replacement Part | | UPC | 019495433002 | | Unit Count | 1.0 Count | | Vehicle service type | Van | ## Product Details - **Brand:** Dorman - **Exterior finish:** Machined - **Item dimensions L x W x H:** 29.1 x 18.5 x 48.5 centimeters - **Material:** Aluminum - **Vehicle service type:** Van ## Images ![603-039 Front Engine Coolant Reservoir for Select Chevrolet/GMC Models - Image 1](https://m.media-amazon.com/images/I/81QWTuaGcoL.jpg) ## Questions & Answers **Q: Will this fit a 1996 gmc safari van with a 4.3 liter engine?** A: Not sure, I own a Astro Van 2003. **Q: This is fit a chevy van 1998?** A: Yes.
