The continual use of a damaged timing chain can prove to be disastrous for your car's engine. By operating the crankshaft and camshaft, the timing chain helps the engine's valves open and close according to proper timing. This directly affects how your car performs on the road.So don't forget to regularly check on parts in the engine bay. When the timing chain's looking a little worse for wear, don't hesitate to get a timing chain kit. The kit contains replacement parts for your car's damaged timing chain, including the sprockets and gears needed to secure the replacement chain.Once installed, the kit's components can offer a more solid grip on the crankshaft and camshaft, allowing your car's engine to work more efficiently. However, make sure you go for a timing chain kit that suits your vehicle best and offers the most benefits.Our timing chain kits here at Carparts come only with the best, highest-quality components.
• Can help the engine's valves work more efficiently
• Comes with OE-fit replacements to damaged timing chain parts
• Made from high-quality materials for longer service life
Four Steps of Proper Timing Chain Kit Installation
Are you having engine problems like rough runs and starting issues? Perhaps your timing chain is already worn out. You should check your engine immediately. If this is the case, you should purchase your new timing chain kit as soon as possible. However, mounting these new engine components can be tedious. Following are the simplified steps on how you can replace your worn out timing chain.
Required skill level: Expert
Needed tools and materials
- Antifreeze mixture
- Car owner's manual
- Drain pan
- Gasket scraper
- Harmonic balancer puller
- Jack stands
- Screwdriver set
- Silicone sealer
- Socket set
- Three-jaw gear puller
- Timing chain kit
- Torque wrench
- Wrench set
Preparing for the actual replacement
The timing chain is located in the engine. Since this is an inner part of the underhood, you would need to remove different components to access the timing chain. This includes disconnecting the battery through the negative cable. You would also need to drain the radiator coolant into a drain pan. After that, you can remove the radiator hoses, fan cutch assembly, water pump brackets, and heater hoses if any.
Disassembling the engine block
To gain complete access to the timing chain, you would also need to remove other engine components. Take out the harmonic balancer with the use of the harmonic balancer puller. After removing the fuel pump, take out the front timing cover. Lastly, rotate the engine using a ratchet and socket until the gears are aligned perpendicularly.
Removing the old timing chain
Once you have complete access of the timing chain and its gears are completely aligned, you can now proceed to taking it out. Remove the bolts on the crankshaft. Pull the timing chain forward and have it removed with the camshaft sprocket. Using the three-jaw gear puller, remove the crankshaft sprocket.
Placing the timing chain kit
The timing chain kit should include new sprockets as these, too, wear out with the chain. With the dots on the gears facing out, slide in the new crankshaft sprocket. Consult the owner's manual and install the new chain and cam sprocket as per the indicated alignment.
Choosing the Right Timing Chain Kit
Although the chain is far more durable than the rubber belt found on a lot of automobiles, it is still one of the vulnerable points in the engine. This guide will help you to pick out the right kit for your ride.
What's in the Kit?
We could cop out and say: "everything you need for a complete installation", but it always pays to know what you are getting when you buy one-after all, you could opt to buy these parts separately. Here is the basic rundown of what you normally get in the kits on-sale in the market:
- Camshaft Sprocket. The camshaft controls the opening and closing of the intake and exhaust valves specifically. This sprocket attaches to one end of the shaft and is the anchoring point of one end of the timing chain.
- Crankshaft Sprocket. The crankshaft controls the upward and downward movement of the pistons within the cylinders in your engine. This is the larger of the two sprockets and is the anchoring point for the other end of the timing chain.
The key thing to look out for when picking out the sprockets is the diameter of the sprockets themselves. Always use your own existing sprockets as a reference and measure out the diameters with a tape measure to be sure. It's always safest to check the diameter you measured against the sprocket you want to get.
- Timing Chain. The chain is the most critical component in the whole kit because it is responsible for making sure that camshaft and the crankshaft moves in perfect tandem-that, in turn, keeps your engine running efficiently.
Proper length and tension are the two important things to look for in a timing chain. Do not use your old chain as a reference point as it might have experienced some distortion or lengthening in its lifetime-even the slightest slackening of tension can be trouble. The best points of reference are your owner's manual or the result of a year-, make-, and model-specific search for a chain on an online retailer's site.
To Kit or Not To Kit
Apart from the three critical components, there are two very big advantages that come with getting a timing chain kit as opposed to purchasing the individual parts:
- You get the right fitting nuts and bolts, among other things, that will save you the hassle of looking for them. This also means that the entire system, when installed, will not be in danger of falling apart due to poorly fit bolts.
- It is a smarter investment in the long run because you not only replace and revitalize on component, you get a brand new set overall. That means that you only have to do a single replacement that can last a very long time.
Changing Out Your Timing Chain
Without a timing chain, you go nowhere. Because of the danger of it snapping while you you're driving at higher speeds, you should start checking up on-consider replacing-your engine's timing chain after a good 50,000 miles. Replacing your own timing chain is very straightforward, and this handy little guide will have you bragging that you handled it yourself!
Time to Complete: 2-3 hours
Stuff You Will Need:
- Timing chain kit
- Combination wrenches & a torque wrench
- Socket set
- Silicon sealant
- Drain pan
- Pullers ? harmonic balancer and three-jaw gear
- Thread-locking compound ? such as Loctite
- Owner's manual
How It's Done:
Phase I: Disassembly
Step 1: Disconnect the battery and allow a half hour to pass before proceeding.
Step 2: Drain the radiator of its coolant.
Step 3: Disengage the upper and lower radiator hoses, all the drive belts, and disassemble the fan and fan clutch assembly.
Step 4: Remove any brackets attached to the water pump at the front timing cover.
Step 5: Detach any hoses that may be attached to the pump and then remove it.
Step 6: With the harmonic balancer puller, remove the harmonic balancer.
Step 7: Detach the fuel pump and any attached lines.
Step 8: Remove the front timing cover.
Step 9: Consult your vehicle's owner's manual to align the timing marks on the gears perpendicularly.
Step 10: Remove any bolts securing the smaller cam sprocket and carefully pull both the sprocket and the chain off.
Step 11: Remove the larger crankshaft sprocket.
*NOTE* On some engines, you might need to use a three-jaw gear puller.
Phase II: Reassembly
Step 1: Put in the new crankshaft sprocket (or the old one if you plan to reuse) and make sure that any markings or dots on the sprocket are facing out.
*NOTE* Never hammer the crankshaft sprocket directly as this can damage it.
Step 2: Install the timing chain then the camshaft sprocket and align properly, referring to your owner's manual as a guide.
Step 3: Secure the camshaft sprocket with the bolts and apply thread-locking compound for reinforcement.
Step 4: Reinstall all removed components from Phase I, taking great care to ensure that all components are where they should be.
Step 5: Reconnect the battery and double-check all connections.
Step 6: Test by restarting the engine, allowing it to reach full operating temperature.
- Be safe! Always wear the minimum in safety gear: goggles, gloves, and closed-toed shoes.
- Always refer to the owner's manual. The steps are general and may require the manual for specifics.
