Hi, Do the Chev Aveo 2011 have a timing belt or a chain? If it breaks, does it damage the valves etc?

The serpentine belt has no bearing on the camshaft timing, so my guess is that you mistimed the camshaft timing for no reason.

The serpentine belt is external and is driven by the crankshaft and runs the alternator, the A/C, Steering Pump and water pump.

If your CAMSHAFT belt broke, the Ford Fiesta has an interference engine, so you have bent valves and damaged pistons.

Does A Ford Fiesta Have A Timing Belt Or Timing Chain?

Ford Fiesta - Timing Belt Or Chain - All 2011 Ford Fiesta engines have a timing belt and are interference. Engine Type, Timing Belt Or Chain ..

what is an air lock

9 times out of 10 its the indicator bulb that's burned out in the dash.

they can when you remove the valve cover can inspect for possible damage

not good thing timing belt break most of the time valves will get damaged you might be lucky my timing belt broke on my 1977 vega monza didnt damage valves but i had timing chain break on 98 lumina got valves damaged.

Absolutely !! That motor is probably an interference motor, meaning the valves must be closed when the piston is up or they will interfere with each other and break something - or several somethings!! I have repaired cylinder heads from interference motors that had a timing belt break - it cost 3 times the rebuild cost due to the extensive damage done when the timing belt broke. It would be considerably cheaper to have the belt changed than to have the head repaired or replaced, as modern heads are thin walled - they will break before older heads would. It could also damage a piston and,as you have hypereutectic pistons balanced by weight ( must be within a couple grams of each other ) 1 piston cannot be changed - they ALL have to be changed, an expensive oops for sure!!!

bent valves worse case but on some cars when belt breaks the internal parts dont get damaged the only way to find out is to dismantle and inspect when putting new belt good luck

you should be ok.. i have never seen valve damage on one of these engines after belt breaking..just retime everything and install a new belt..make sure you check water pump and tensioner bearing for looseness/wear

The timing chain should of been changed at 30,000 or 60,000 miles it's in the owwners manual.

just go to any junk yard and find a used deawoo lanos and pull the head if timing belt was not broke, if it looks good, its a exact fit 100%, no special tools needed, just normal wrench set and torqe wrench. after head is installed, get a gates timing belt only.
