Yes, If the timing belt brakes or skips several teeth. The 2.0L Suzuki engine pistons will and do hit the valves under that condition.
You should change that belt at 100-120k miles.
You can start by R&R the timing belt and setting everything back to specs,
Do a compretion test - that will be your awnser. Low or no compretion + bent valves.
The cheepest fix is a certified used low milage motor - put your new timing belt on the used motor for good measure.

The knob cover easily pulls off. To remove the entire control, pry trim panel off, then remove screws that hold on controls and remove it.

SOURCE: 2005 Suzuki Forenza timing belt breakage

hi im not sure on this particular model but there a few easy ways to check.... take the spark plugs out, remove the broken belt, shine a light down the holes and look for dammdge, if you cant see anything you can turn the crank but it is a tricky job because you can ruin the engine so if your unsure get a mechanic to do it.. or your other alternative is to remove the head and have a look but you will need a new head gasket kit, timing belt and tensioner kit etc .. it is important that you do not turn the engine over when the belt is disconected in any way UNTIL you know for sure that valves wont hit pistons, even bending a valve will not be very noticable but when its all back together you will deffinately notice and will have to pull it all back apart

It seems to me that if the belt breaks , even on an interference engine: the valves will slam shut . Maybe it 50/50 chance either way.


belt has to be replaced any way
compression test on the cylinders.. tells you straight away
zero or low compression numbers ..valves bent

in an interference engine OHC or DOHC belt breaks
the cams stop dead and pistons continue to move up and down

non interference there is a gap between pistons and valves

My timing belt broke on my 2003 hundred Santa fe . I need to figure out if the valves or Pistons were damaged.


every cylinder do a compression test

if low or no compression
heads off to repair and check piston damage

if original motor is beyond repair
you can fit a used motor in from a wrecker

when timing belt breaks
it is the type of engine.. that pistons will hit valves
bend them or damage valve guides in the heads

2.4 liter, timing belt or timing chain?


Timing belt. This engine is an interference engine. Ensure the belt is replaced before it breaks to prevent internal engine damage. If replacing it as a DIY project, be sure to follow all procedures carefully as improper procedure can also result in valve or piston damage. If the belt has already broken, the odds are better than 90% that the cylinder head will need to be repaired or replaced and the pistons will need to be inspected for damage.

Whhen to change timing belt


Most companies recommend replacement at or before 80,000 miles. It is an interference engine which means the valves can be damaged if the belt breaks while the engine is running.

Timing belt keeps jumping tim 3 times know reset runs good for awhile


You have a bad timing belt tensioner. Stop driving it because you are probably due for a new timing belt also if the tensioner is bad. If the timing belt breaks while you are driving it, serious damage may occur like a valve punching through a piston, bent valve, damaged cam, serious stuff can happen if the timing belt breaks.

Broke a timing belt, do the valves stike the pistons when timing belt breaks on a 2.3l engine and if so does damage consist of a mark on the piston or does it break the piston.


I think that that all motors now days are 0 clearance valve trains, this doesnt allways mean there is not damage. change the belt and find out! have a good one !! you can go to any auto parts store and buy a haynes manual for your car. they are based on a complete teardown of your car. they are only about $25.00, the instructions for the belt are in there have a good one !!

We have a 1994 Suzuki Side kick in for work and the timing belt broke on it. We would like to know if the valves bend when this happens.


nearly or perhaps all of the suzuki side kick engines are "Interference Engines" .. that means when the timing belt breaks, if the engine keeps spinning then pistons will collide with some valves that are left open .. that can damage those valves and or pistons .. that usually increases the cost of repairs .. on "clearence" type engines.. when the belt breaks you just coast to a stop with no damage done .. but high performance engines are often "interference" type .. with them its extra important to change the belt on schedule since the potential for expensive damage is great .. ..

When timing belt goes dose it reck valves. do they hit the piston.


Best Answer - Chosen by Voters Basically the timing belt connects the crankshaft with the two camshafts. This allows the valves to open allowing air into the engine at the right time. If the belt breaks then the crankshaft along with the piston and rod assembly will still move but the valves will be still. This can cause the piston to collide with the valves which can cause damage to the pistons, valves, and the entire head in some cases. There is a chance of nothing getting damage though. There are interference and free-wheeling engines. The difference is that free-wheeling engines has a space between the top of the piston and the bottom of the valve so if the belt did break then the valve would not hit the top of the piston
