Review on πŸ”‹ Dorman 603-109 Front Engine Coolant Reservoir: Ideal for Chevrolet, Oldsmobile, and Pontiac Models by Jeff Labore

Revainrating 2 out of 5

Not so great. The coolant leak appeared after the overheating issue was fixed.

I would not recommend purchasing this coolant reservoir. There were two main problems. The first issue is the gasket in the lid that comes with the kit. The seal kept breaking. The second problem is that the coolant flies out of the pipe. The second problem was not caused by the first. I replaced the cap with another one, but coolant continued to leak from the tube. After replacing that tank with another one with a different type of cap and no hose, I had no more problems.

Pros
  • Constant test results
Cons
  • thin
