Review on Dorman 603-139 Pressurized Coolant Reservoir: Optimal Performance for Efficient Engine Cooling by Dustin Keller

Revainrating 5 out of 5

Great little tank! for coolant rebuild kits

Purchased to replace a worn rust colored factory part. Arrived and fits perfectly. Now I can actually see my coolant without having to shine a flashlight into it. Save and reconnect the original overflow hoses.

Pros
  • Robust design based on 100 years of automotive aftermarket experience
Cons
  • Not as thick as other kits
