Review on Dorman 603 237 Coolant Reservoir by Tim Hull

Revainrating 2 out of 5

Does not fit 2006 Buick Lucerne with Northstar 4.6L V8

Buick Lucerne 2006 with 4.6L V8 The build quality was good overall. However, this won't work if your hose has quick disconnects on the end. The OEM reservoir has a "lip" 2-3 inches above the end of the joint (circled in red in the attached image). I ordered this part but there is nothing in it that will prevent the hose from staying connected under pressure.

Pros
  • Rugged construction - made of quality materials to withstand heat and vibration under the hood
Cons
  • Safety
