Product Details

The Dorman 603-446 is a front-mounted non-pressurized coolant reservoir designed as a direct replacement for select Toyota vehicles. This recovery tank collects excess coolant as it expands during engine operation, preventing contamination of the engine compartment and environmental spillage.

Key Features:

  • Direct replacement design matches the fit and function of the original equipment
  • Durable white plastic construction withstands underhood heat and engine vibration
  • Includes vented reservoir cap for proper cooling system operation
  • Recirculating design returns cooled fluid back to the cooling system
  • Engineered for seamless installation with stock mounting points
  • Quality-tested to ensure OE-level performance and reliability

This reservoir is manufactured from quality materials specifically chosen to resist the thermal cycling and vibration stresses common in engine compartments. Backed by Dorman's 100+ years of automotive aftermarket experience, this coolant reservoir provides an excellent value alternative to dealer-priced original equipment parts.

Why shop on Ebay, when there is Autoplicity. Cheaper prices than Ebay, Faster shipping and good return policies.

I called to see if it would ship before I needed it to go on a trip. I gave bad information about my order, but the employee went out of his way to track down my order and made sure that it went out ASAP. Thanks guys!!!<br><br>

I couldn't find this part anywhere! That's until I found Autoplicity! Thanks Guys!

Arrived in 4 business days and cheapest price on the web for the part I got.

Great prices! Wonderful customer service!

I ordered a rear sway bar for my MINI Cooper on Sunday and it was at my door on Wednesday! Autoplicity had the absolute cheapest price for this bar and I was very impressed with the shipping speed. I would definitely recommend them to my friends!

Fast shipping and a great product at an unbelievable price! Thanks!
