What is this part and why does it matter?

The radiator transfers heat from the engine coolant to the outside air, keeping engine temperature in a safe operating range.

For an engine radiator, compare dimensions, hose ports and mounting points. Air conditioning, engine and transmission options can require different variants. An air-con condenser or intercooler is a separate component. Confirm the listing contents and the described condition of fins, end tanks and mounting brackets.

Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

  • Coolant leak visible on the radiator core or tanks
  • Engine overheating
  • Coolant looking rusty or contaminated

Installation information

Requires draining the coolant before removal, and refilling/bleeding the system properly to remove air pockets afterward.

Frequently asked questions

Most often corrosion or age-related cracking in the core (especially on older metal radiators) or in the plastic end tanks on modern designs.

  • 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.
