Hi Zabo! This Dorman - HD Solutions Coolant Reservoir (Part No. 603-5103) is a direct fit reservoir for the specific vehicles. However, to check an exact fit application for the part number 603-5103, please provide us with the year, make, model and engine size of your vehicle.
Will this work in a 04 Mazda 3
Verified Reply - Vincent
Hi Cwill! This will not fit your vehicle. Currently, the exact coolant reservoir for your vehicle is unavailable online. I would recommend that you check with the nearest Advance store and one of our parts pros will be glad to assist you with an alternate availability.
