Review on Dorman 603-054 Front Engine Coolant Reservoir: Ideal for Cadillac, Chevrolet, and GMC Models in White by Andrew Enriquez

Revainrating 3 out of 5

Observe the nominal pressure of the cover!

Cap is incorrectly rated. This unit came with a 20psi pressure cap. The OE specification is 15psi. I had to use the original cap instead of the cap that came with the tank. The black upper hose nipple is slightly smaller than the original. There were some problems with the sealing.

Pros
  • Perfect solution - designed for a seamless installation
Cons
  • Small parts
