What is this part and why does it matter?

The coolant reservoir (expansion or overflow tank) stores excess coolant as it expands with heat and provides a low-pressure point to check coolant level safely.

Frequently asked questions

Most often from age and heat cycling making the plastic brittle, or from the cap seal failing and letting pressure build unevenly.

  • I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

  • No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

  • Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
