Product Details

The Dorman 603-376 Engine Coolant Recovery Tank is an OE Solutions direct replacement designed to restore proper cooling system function in your vehicle. This pressurized coolant reservoir is engineered to withstand the extreme temperature fluctuations and pressure cycles that occur during normal engine operation.

Key Features:

  • Durable plastic construction resists expansion, warping, and cracking from heat exposure
  • Pressurized design maintains proper coolant system pressure for optimal performance
  • Leak-resistant construction prevents coolant fluid loss and system contamination
  • Direct-fit OE replacement for hassle-free installation
  • Built to match or exceed original equipment specifications

This coolant recovery tank captures overflow coolant as the engine heats up and returns it to the radiator as temperatures cool down, maintaining proper fluid levels and preventing air pockets in the cooling system. The robust design ensures long-lasting performance even under demanding operating conditions.

Excellent Service

The one star for customer service is not necessarily anyone's fault. I received 1/2 of my order, sent in a request for information on the other 1/2 but never received a reply. However, the rest of the order did show up the next day

Awesome

OVERALL EXPERIENCE VERY SATISFYING.

Very fast, super easy.

Easy site

Quick and easy!!! The shipping was FAST, the packing was great and the merchandise top notch! The shipping and order notifications were also much appreciated. Great place to get Auto goodies. I will definitely be back to Autoplicity!

Good website

Easy to use and check out

I was apprehensiveness at first to make a major purchase with Autoplicity due to their extremely low price and lack of reviews. I decided to take the chance and I am very glad I did. I made my order on a Monday morning at 0900 eastern time and my product arrived on Wednesday at 3pm. The item was exactly as described and the most astonishing part is that my purchase was released from the factory less than 45 days ago. I was expecting a model that had been sitting on a shelf for the last year and needed to be updated. That was not the case. I will definitely order from Autoplicity again in the future.

Great prices fast shipping bookmarked website!

clear product description. Quick checkout process.

My shopping experience has been great...it was very easy to find the part I was looking for.

Nice price on tie rod ends i needed fast checkout

So far So Good
