I realize that a Chilton/Haynes might answer this for me but I haven't bought one yet. Unless you can think of a way to keep the chain from getting slack as you do it ? If the chain goes slack, the adjuster takes up the slack, and you have to dismantle the front to reset it. I don't think so - the cam chains have automatic tensioners that will take up slack - that's why we use wedges when swapping 4.7 cams. Might be a recipe for disaster for the installation, though. It was better than nothing, but severly lacking on information if your used to Chilton manuals.Īny chance these heads will come off without taking the front of the motor apart? Can I just unbolt the cam gears and the guides from the heads, then slide the heads up and over the cam gears/chains/guides? Seems like this would save several hours of work over disassembling the front of the motor.
2000 dodge dakota timing chain replacement manual#
The Hanes manual was a total POS, told me to remove things that didn't need to be removed and missed other things. I bought a Hanes manual (only thing I could find on short notice) for my 03 Dak while dropping the tranny. There is no water in the intake manifold so no way it is coming from there.Īs far as I know, there is no head gasket issue on the 4.7's.ĭo yourself a favor and buy a Chilton manual for the truck. He (my neighbor) just changed the plugs - I haven't looked at the old ones yet. He's got the excessive white exhaust and low coolant level. Is this (head gasket leak) common for the 4.7? Or is there any way for the burning coolant to be an intake manifold port leak or something else? Just trying to diagnose this before pulling it apart. Do the cams have to come out for access to the head bolts? Head bolts must be replaced? Anything else to change/fix while I'm in there? Thanks for the info,Ĭouple of questions. I will definitely get a book that covers the steps - I don't want to wing it and mess it up. The head gaskets are multi layer metal and come off pretty easy as well. The intake and valve covers come off easy and those gaskets are reusable. You WILL have to pull the timing chain covers and remove the secondary chains to each head. RE: Any tips -changing head gaskets on 4.7 I still have to check into buying a manual or checking online for any specs and/or procedures. Any tips on this job? Any special tools? I just did the heads on my 5.9 Durango so I'm hoping it's not much different. My neighbors 2000 (4.7) with 140k miles just started sputtering and then blowing white smoke. Prices for timing chain replacement may vary anywhere from $370 to $1,500 depending on the vehicle model.Subject: Any tips -changing head gaskets on 4.7 Many cars have two or even three chains in their motors and often your auto repair shop may recommend replacing all the chains at once. If the timing chain is worn, it's usually replaced as a kit with a new tensioner, guides, and other parts of the chain drive mechanism. The timing chain noises can range from rattling to whirring, whining or buzzing. A worn timing chain, chain guides or chain tensioner can also cause a variety of noises originating from the timing chain cover area of the engine. This is because as the chain wears out, it stretches and the ignition and valve timing becomes more retarded. The Check Engine light might come on too. Often, if the timing chain is worn, the engine may feel a bit sluggish, low on power or have trouble starting. How do you know if the timing chain is worn?
See timing chain animation.Ĭhain guides and silencers are used to keep the timing chain from vibrating. Timing chain, tensioner and chain guides. For example, we often see timing chain failures in older Ford trucks, Chevy Ecotec engines and in older Honda and Nissan vehicles. In some cars, the timing chain can last for the lifetime of the vehicle, but in others it is know to wear out sooner. Lack of oil changes, low oil level or poor oil quality can cause the timing chain to wear faster. A timing chain is lubricated by the engine oil. Like any other moving mechanical component inside any engine, a timing chain wears out and stretches. Timing chain problems are not uncommon, especially in high-mileage vehicles. Does it mean that the timing chain immune to mechanical failures? A timing chain doesn't need to be replaced unless there is a problem with it. A timing chain runs inside the engine, as it needs to be lubricated by the engine oil.Ī timing belt typically needs to be replaced between 60,000 and 100,000 miles depending on the vehicle. A timing belt is a toothed belt made of high-quality rubber it runs outside of the engine, covered by a protective cover.Ī timing chain is made of metal, similar to a bicycle chain.
