Pretty simple job with the exception of the balancer. Disconnect the battery and drain the cooling system. Remove the water pump and any associated brackets and belts. Remove the lower pulley and using a harmonic balncer puller remove the balancer. Remove the bolts holding on the timing chain cover including in some cases the two front oil pan bolts. May want to loosen the four front just for ease of reassembly. Tap not start the engine or turn by hand until the timing marks line up should be one on the crank pulley and one on the cam gear. Remove the three bolts saving the metal retention tab for renstall, Use a big cold chisal and a hammer and smack the crank gear splitting it in two. Reinstall the crank gear by tapping it on to about the proper place, reinstall the cam gear making sure the marks on the gears line up (:). Once this is done check the rubber gasket for the bottom of the timing chain cover if it has two large ears one on each side these go between the block and the pan sometimes it is easier to cut these off and using a good dab of sealent at the corners. With the timing cover gasket installed on the cover, Line up the dowell and install the cover Put a bolt in at each side and concentrate your effort on the pan making sure it seals to the block and the cover. Tighten the cover on like you would tighten a wheel and do it in two steps. Tourque to about 8 lbs. Reinstall the balncer using a balancer installer and the lower pulley and belts, the water pump and brackets. Refill the cooling system start the engine and time to specs. Two things also change out the seal in the cover if it did not come in the set, inspect the end of the crank for a groove. If the groove is deep ask for a speedi sleeve fel-pro makes this and install over the end of the crank snout covering the groove. This groove is caused bt rubbing on the seal. It will leak oil for sure if the groove isn't fixed or you did not get a good seal betwen the cover and the pan.
The timing chain itself is not hard to change , but the engine has to be removed to do it, that is why it is such a costly job if taken in to a garage . a common fault i believe on these engines .
Chevy Metro 2001 (1.3 L) has a timing belt - hard driving conditions require its replacement at 60,000 miles, otherwise the timing belt replacement is scheduled for 100,000 miles.
With the proper tools and information it is not a hard job.
the water pump is in with the timing chain, and is very hard to get to. If you will look under your exuast manifold you will see it to change it you have to your manifold off,altinator,belts, balancer,exc just have someone do it
Need to know the engine number as in sr20e or ga16de to help you.
By drive belt; I assume you mean a timing belt. On a 3.0 H-6, there is a timing chain in place of the belt (Very durable). It is housed behind cast aluminum timing chain covers on the front of the engine. On an engine with a timing belt, I would do the change myself; but I recommend that a timing chain be replaced by a Subaru dealer simply for the fact that the tension, alignment, and timing can be hard to set yourself with a chain.
no it has a timing belt. it's not that hard to replaced
Yes, if the timing chain or gears are worn, acceleration can cause the chain to jump.
The colored links can be very hard to find on a used chain. It helps to use some brake cleaner to remove the oil on the chain.The colored links can be very hard to find on a used chain. It helps to use some brake cleaner to remove the oil on the chain.
You'd have a hard time breaking a small block Chevy timing chain. As the chain gets loose it will run worse and worse. But to anser your question. No, the chain coming off won't make the valves hit the pistons, but it would make one awful racket as the chain got wound up on the crank gear and smashed through the timing chain cover and from face of the oil pan. ;)
If it is noisy, the engine timing is hard to maintain, or the engine is performing poorly, it may need changing. Timing chains are very durable and usually last the life of the engine or until it needs an overhaul.
every 100K miles, unless you drive it really hard ... if so, replace it sooner
