Wet belts dont like new fuel, and dont like low mileages... Found the below information which backs up what ive been saying for a long while, the ecoboost engines are fine...if they cover high mileages and oil is changed regularly.... Dayco, a leading belt manufacturer, has investigated the impact of ethanol and petrol contamination on its timing belts. Their research has indicated that the presence of fuel in the oil, especially due to short, low-speed drives, can overwhelm the oil’s additives and cause belt degradation. This means that the belts may fail before their expected lifespan, even if the belt itself is of high quality. The Importance of Proper Maintenance and Usage: To mitigate the risk of premature belt failure due to ethanol and petrol contamination, it’s crucial to maintain a vehicle properly. This includes avoiding short, low-speed journeys that can lead to fuel contamination of the oil. Regularly changing the oil and ensuring the oil filter is in good condition can help prevent fuel from entering the engine oil. If a vehicle is stored for extended periods, it’s advisable to use fuel stabilizer to prevent ethanol from separating and potentially damaging the fuel system, including the belt.
Get Dayco. They are made in Italy anyway and from the dayco "HT" material.
I have them in my 2v no issues

I got my kit from MetalMan Parts. Dayco timing belt, Continental serpentine belt, Litens tensioner, INA rollers, Graf metal pump and all the recommended hardware \ud83d\udc4d
Be careful who you purchase from. I bought one a year or so ago everything was great but the timing belt itself broke. I got lucky and didn't bend any valves. Bought a Dayco belt and haven't had any problems.
Der erste Zahnriemen war 28 Jahre alt und hatte 105.000 km gelaufen. Beim Abnehmen merkte man, dass er merkwürdig elastisch war und die Zähne wie Gummi, aber er hat gehalten. Die Wasserpumpe und Rollen waren tadellos. Der ganze Kram war von DAYCO. Was für Qualität! Hat mir den Motor gerettet.
La voiture de mon pote avait une courroie Dayco qui était en bon état à 65 000 + miles
Vote 1, for Dayco Timing belts
Dayco, continental should be fine, as long as it’s not China Amazon stuff. Gates it usually good but as with anything these days quality control is a crap shoot.
Dayco is an OE manufacture for many manufacturers, it's a pretty solid belt. Quick answer is yes you should get it changed ASAP, I've seen a lot worse belts than this one and they drove to the dealership just fine.
