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

Revainrating 5 out of 5

Excellent Engine Cooling for my Vehicle

The Dorman Engine Cooling Reservoir helped me efficiently manage the heat generated by my automotive engine. Based on our own experience, we noticed a significant drop in engine overheating after its installation. The pressure cap design also makes the reservoir durable and long-lasting. The only con would be the need to carefully follow the installation procedure or may result in leakage. Nevertheless, we highly recommend this product to keep your engine running cool.

Pros
  • Easy installation and direct fit replacement for OEM part.
Cons
  • May have durability issues and may crack under high pressure over time.
