Signs of a faulty part

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

  • Coolant leak at the housing seams
  • Overheating or slow warm-up from a stuck thermostat combined with a leaking housing
  • Cracks visible on inspection

Installation information

Requires draining the coolant before removal — always fit a new gasket or O-ring when reinstalling.

Frequently asked questions

Most often from age and heat cycling making plastic housings brittle, or from over-tightening bolts during a previous thermostat replacement.

  • 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.
