Car overheating I have 1997 J2 Elentra SW- Changed the cambelt,car started overheating. Can't be valve timing, cause if one tooth out the car would not start

Some fixya user told me a website reliable-store it is very good.. I used it to repair my shredder it had some spark issue which wasn't easily fixed. you can go there and try

rocam engine does not have a toothed cambelt ,it runs on a timing chain

Could be the second fan motor or a relay. Have the circuit tested for the second fan.

Hi guys, I just want to now if someone can tell me if a hyundai getz 1600 16v 2004 can bent valves if the cambelt snaps. I did put a new cambelt on and tensioner. It start but misfiring and a soft tickking noise from the head. Hope you can advise me please. Thanks

Oh No!

Firstly, I suspect your engine may be what is called an Interference Engine - this means if the cambelt breaks, it usually causes internal damage.

If you can you please advise your engine model code, I can confirm if this is the case?

I assume that you mean the cambelt idler bearing.Ok if you are sure that the timing is correct for all cams(DOHC)?.Then the problem may be bent valves caused by the bearing collapse allowing the cams to go out of timing and cause valve strike.
I would recheck the timing,ensuring all marks line up precisely,the only one that should look 1/2 a tooth out is the crank.Genuine belts are always preferred for these as they have all the markings on the belt to align all the cams and crank,some other suppliers do not have this
I hope that this helps you,or get back to me with your findings.

remove your valve cover and have someone try to crank it over while you watch the camshaft to see if it turns, your timing belt may have jumped a tooth ( causes bad running and back fire ) and then broke

You must reset the timing cause you can not reset just one tooth on it and yes you have to lock itin place cause the tentioner can nock it out of place when you increase the preasure

Do you know if the engine timing is correct? If you get the timing a tooth out you very similar issues, has the cambelt been replaced recently - or is it over due??
Another posibility is the cam chain adjuster. This is oil pressure fed and I think controled by a solnoid, it applies a force between the chain that drives the inlet camshaft from the cambelt driven exhaust camshaft. (Making any sense? Let me know if you want me to simplify) This operating correctly advances and retards the valve timing, when faulty it can make it incorrect. Non start is a fault caused, but more often they become very noisey.
The cam chain adjuster is fed oil when the car is started, you can breifly here it before it has reached operating pressure on normal start up, sounds like a diesel knock for a second, then goes, this is normal. If it continues, its more than likely faulty.
Let me know if you want any more info. If the sensor and wiring is good you'll probably have a timing issue.

You need to rotate the cam until timing marks on the sprocket are in line with the head, then make sure crank shaft timing mark is lined up. Install the belt. Might have to loosen the timing belt tensioner. Put timing belt tensioner back on, rotate the crank shaft with a wrench first to make sure there's no interference. Next, check compression.
