Review on Dorman 603 070 603070 Fluid Reservoir by Andrew Aldana

Fits my 2004 Mountaineer with a 4.0 SOHC engine. The factory one leaked at the seam and was dirty yellow. This detail alone makes a striking visual impression under the hood, not to mention that the cooling system does not leak and keeps the correct pressure. I found the cap that came with this tank to be of lower quality as it only gave out 14psi of pressure. I replaced it with a motorcycle cap which I checked for the correct pressure with a coolant pressure gauge.
