Is it dangerous to drive with a leaking housing?

Not immediately, but ongoing coolant loss risks overheating — repair promptly and monitor coolant level in the meantime.

Should the thermostat be replaced when replacing the housing?

It’s common practice to replace both together, since the housing needs to be opened for access anyway, and it avoids doing the job twice soon after.

What is the housing made of?

Aluminium or heat-resistant plastic, depending on the engine.

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.
