On the 2010-2016 Fiat Uno, the chronic Achilles' heel of the Fire Evo 1.0 and 1.4 engines used in the Novo Uno through 2016 is the thermostat valve housing (carcaça da válvula termostática), which is made of plastic. With age and engine heat the plastic dries out, cracks and starts leaking coolant. Owners notice the coolant level constantly dropping and a sweet burnt-coolant smell from the engine bay; if ignored, the leak progresses to overheating, which on this engine can lead to head gasket failure. The problem is so widespread that the Brazilian aftermarket sells dedicated aluminum replacement housings for the Uno/Palio Fire Evo specifically to fix it permanently.
Replace the cracked plastic housing with an aluminum aftermarket housing (widely available in Brazil for the Fire Evo) together with a new thermostat, seal and fresh coolant. The part is inexpensive and the job is straightforward. On any used Fire-engined Uno, inspect the housing for seepage and check coolant level history as part of pre-purchase inspection. Never keep driving with the temperature gauge climbing — head gasket damage costs many times more than the housing.
