hello,i would like to change the belt to my cmax 2009 125ps 1.8L. since two days i try to do it using two belts but in vain. the old belt is 6PK1213 made in usa and the new two belts are 6pK1213 made in usa and 6PK1240 continental made in germany but these new belts don't want to fit, they seem short,l used the idler/tensioner many times to right side unfortunately without success. maybe i must to buy another belt more long? any help please

Looking a the photo on my phone 

The original look's like 6PK1540

Can you get the old belt back on now?

Have you measured the new belts directly against the old one?

Those stretchy belts are one of worst ideas car manufacturers had. I hate them. 

You will need quite a bit of force ( using a snug fitting bar in the tensioner hole ) to force the belt on.

I'm going crazy because I can't insert these straps, I tried to insert the old one too but unfortunately I couldn't

i hate them too also this kind of tensioner

Have you tried putting the new belt in a bowl of very hot water for ten minutes to help it soften ?

As above then, it's just tight because it's a stretch type.

no, I just tried putting it in the oven at 70 degrees for 15 minutes. but i'll put it in hot water

 

I really appreciate your responses.

Unfortunately, it's raining here today. I hope it stops and I'll try putting it in hot water.

I'll let you know how it goes.

thankyou so much 🙏

hello,after using hot water,unfortunately it didn't work. i think i will order 6pk 1249 hoping it works better. 

thankyou so much to all of you,you have been truly kind 👍

hello, today i used the original belt and worked very good
