Hi, just letting you know my timing belt just went on my daewoo lanos. unfortunately it seems in a daewoo lanos that when the timing belt goes, it can do damage to one of the valves. mine is in at the mechanics and i am still hoping that it hasnt done any damage. i was also told that if you have replaced the timing belt and the car still wont start it has definitely done damage to a valve. sorry to give you the bad news!!

Timing belt diagram daewoo nubira 1998


Here are the written instructions, i do not have the pictures, it is a very good set of instructions and clearly written.

Required tools:

13mm open end wrench 10mm shallow and deep socket 8mm socket long flathead screwdriver 17mm deep socket T50 torx socket 1/4", 3/8ths and 1/2" ratchets and extensions E10 inverted torx sockets 6mm Allen wrench 15mm open end wrench 7mm socket 12mm open end wrench 14mm socket 12mm socket 8mm, 9mm and 10mm Allen head sockets 19mm socket pry bar needle nose pliers

If you are doing this because your timing belt broke you will also need to buy a complete cylinder head, head gasket set, and both idler pulleys. ALL DAEWOO MODELS WILL BREAK THE INTAKE AND EXHAUST VALVES WHEN THE TIMING BELT BREAKS.

Start by removing the air cleaner assembly from the throttle body, remove the air filter and housing jack up the vehicle and remove the wheel, remove the plastic shielding in front of the accessory drive belt assembly, remove the accessory drive belt, place a jack with a block of wood on top underneath the engine oil pan remove the front engine mount, remove the crank shaft pulley ( the 4 Allen head bolts only not the 17mm bolt in the center.) remove the metal plate behind the engine mount bracket on the engine, remove the plastic timing belt cover 3 clips on top 2 10mm bolts on bottom. Rotate the engine until the #1 cyl. is at Top Dead Center on the compression stroke or line up the crankshaft timing mark with the mark on the inner timing belt cover ( notch in cover with notch in pulley) on the camshaft pulleys -- ( intake cam line up the line on the pulley with the line on the inner cover)( exhaust cam line up the arrow on the pulley with the arrow on the inner cover) loosen the 13mm bolt in the belt tensioner and using the Allen wrench rotate the tab until there is slack in the belt. Remove the belt. At this time I would recommend you replace the water pump, both plastic idler pulleys as they tend to overheat and lockup, and the belt tensioner. Make sure all your marks are lined up, you may need a helper to hold the Exhaust Cam in place as it tends to move during belt installation. Put the timing belt underneath the crankshaft pulley, install the belt leaving the intake cam for last and NO BELT SLACK on the right side between the crank and the exhaust cam. Once the belt is installed rotate the crankshaft over 2 revolutions and make sure is rotates freely, and your timing marks are aligned perfectly if not the engine will not run properly, tension the belt as needed. Installation is the same as removal.

How to replace a broken timing belt for a 1998 daewoo lanos?? Would there be any head damage?


yes it is quite possible that valves are bent if the cam belt broke or teeth stripped off of old belt, which unfortuneately means removing the cylinder head and getting it repaired (valves replaced and possibly guides) see some of my other posts for cam belt timming marks locations etc...
depending what motor is in your vehicle twin cam or single?

stevenhurc_14.jpg and if its twin cam you usually need cam locking tool for cam gears.

Hello emissionwiz it looks that you know about this vehicle. I just purchased a Daewoo Lanos 2001. They advised me that the timing belt broke and that the tension pulley broke. I went to a u pull yard and...


if the timming belt broke when the engine was running most of the time the valves get bent and leak (head off repair) you could check this once you have replaced the belt before you start remove rocker cover and check for gaps between cam lobe and valve bucket when lobe is not pushing bucket down if there is a gap valve is bent.
these vehicles came out with a single cam or twin cam engine also so which one have you got?
valves bent on both engines when belt broke while running

on single cam engines you lock the tensioner with pin and loosen water pump and turn to obtain correct belt tension then release lock pin in tensioner and check that marks on tensioner align up if not turn water pump to get correct. some times this then causes the seal on the water pump to fail if its been there for some time because they corrode in block and its only a "O" ring so you might need a waterpump and "O" ring and coolant use grease on waterpump and "O" ring to make sealing and turning if needed eazier.

ifyou need any more info let me know even if twin cam can send pics also

To clarify, on the DOHC engine, the intake cam gear has a line on it, and the exhaust cam gear has an arrow on it. These should be lined up with the corresponding line and arrow on the VALVE COVER, pointing straight up. I just went through this process over the weekend, and spent quite a bit of time looking for these marking as I had removed the valve cover. Once I found them, it was plain and simple.
In addition, be sure to not over tighten the belt when reinstalling. The tensioner has markings on it for "old" and "new". DO NOT adjust past "new", as the car will sound like a jet engine, and the belt will not last for very long.
One more item that you may as well replace while you are in there is the cam position sensor if you have not already, as there have been issues with them, and the timing housing has to be opened to get to it

Looking for cambelt timing marks/ positions please, Twin cam engine Thanks Kevin


these bend valves if belt breaks while running
Align the timing marks on the camshaft gears to the notches on the camshaft cover, using the intake gear mark for the intake gear and the exhaust gear mark for the exhaust gear.
Align the mark on the crankshaft gear with the
notch at the bottom of the rear timing belt cover.
