no , that is not really true, but it is good sense to replace both while you already have engine torn down
Firstly having the right specialized tools for the job makes it a whole lot easier, however, it is not essential if you take precautions. I do not recommend the job if you are not reasonably mechanical but of course if you were you wouldn't be asking! Once every thing is removed and the timing assembly is exposed, before removing anything else, if reusing chains and only replacing guides MARK THE CHAIN ON THE TIMING MARKS. if you have the correct tools fit them to the camshaft bolts before removing tensioners, if not, you will need a second person to assist in holding the camshafts in place with a spanner so the cam doesn't spin and let valves make contact with cylinder heads. once tensioner is removed that guide pulls off, then remove the two bolts holding the other guide and remove. Reverse this sequence to replace. If replacing chains as well a new chain will have links marked for position over timing marks on sprockets. If for some reason you need to refit an old chain just lay it out stretched together and mark the two folded end links, this gives you your positions over timing marks. Be sure to replace gaskets as these motors are temperamental to second time use.
The timing chain cover on you 4 cylinder Saturn is ALSO the oil pump, so it's a significant part of the engine.To remove the cover/pump:Jack up the front of the vehicle and put it on jack stands or other safe supports. Never climb under a vehicle that is not safely supported and never trust a jack.Remove the right side (passenger side) tire.Remove the mud shield to expose the pulley end of the engine.Remove the serpentine belt.Remove the dampener pulley (that's the pulley that drives the serpentine belt)Remove any peripherals that interfere with removing the cover.Support the engine then remove the upper passenger side engine mount.Remove the camshaft cover.NOW you can finally get to the timing chain cover.Note that the Saturn 4 cylinder engines (1.9 either the single cam or dual cam) used an oil bath timing chain rather than a timing belt, and generally, if the engine has been properly maintained, there is no need to replace the timing chain until it's time to rebuild the engine.
No , actually the Ford 300 cubic inch / 4.9 liter inline ( straight ) six cylinder engine has gears that mesh with each other on the front end of the crankshaft and the front end of the camshaft so it doesn't use a timing chain or a timing belt
Has a Timing CHAIN. It does not need replacing for life unless it gets abused with other engine internals if yu don't do your Oil changes as required. No Belt is used on the 2.4! Only the 3.3 V6 Highlander has the Timing Belt and must be changed on a scheduled mileage/time basis.
Hey Luis==Get a ,manual on your car from a local parts store or from MOTORLIT.COM These come in handy on other repairs and help yo get acquainted with your car. GoodluckJoe
The timing marks for a 2002 Ford Explorer are located on the timing chain and cam shaft sprocket. They must be aligned with each other to set the initial timing.
The 2.7L has a timing chain. All other engines have a timing belt.The 2.7L has a timing chain. All other engines have a timing belt.
The 4.0L will need the timing belt replaced at 100,000 miles. All other engines have a timing chain.
Depending on how novice you can go after the waterpump, if you have other transportation. The Astro has a timing chain, and I wouldn't replace it as a maintenance item, you'll be getting over your head if your not careful.
You don't have a timing belt, you have a timing chain..(that's for the other foreign automaker...that charge way to much at the lot..but are way too cheap to give you what you pay for.) you timing chain is located under you valve cover gasket, you would have to remove it in order to get at the chain.
A timing chain typically doesn't need to be replaced until you tear down the engine for a rebuild. Unlike a timing belt, which is operated dry, the timing belt is in an oil bath and will last much longer. If your engine needs a valve job, rings, oil pump or any other components that require a "tear-down", that would be the right time to replace the timing chain, sprockets and chain tensioning rails.
You have to pull the engine apart to replace the chain. There is no other way to get the chain around the crank shaft. I would HIGHLY recommend getting a repair manual before you start something like this.
as long as you have the timing marks set right on the timing chain gears the only other thing it could be is your distriburetor is set wrong.
You may never need to on this car. Timing chains are far more durable than the belts on other cars.
Piston slap and timing chain related noises can be very similar. If it is a piston slap noise the noise may be louder during power braking and may quiet down as the engine warms up.
A 2.7L has a chain, all other engines have a belt.
redo the timing or replace the whole kit - I might add that replacing the entire timing chain as a kit is what you would do when you find out that the timing chain is bad. The question was what happens when the timing chain is going out? 1. It may get or be harder to start the engine 2. The engine performance will be down 3. The ignition and cam timing will be unstable 4. The engine has a greater potential to "jump" timing or become mistimed. This could lead to bent valves and other problems which are more expensive to fix.
