How to change the timing chain on a Mazda 6?

1. Disconnect the negative battery cable. 2. Remove the spark plugs. (See SPARK PLUG REMOVAL/INSTALLATION.) 3. Remove the tire (RH). 4. Remove the under cover. 5. Loosen the water pump pulley bolt and removal the drive belt. (See DRIVE BELT REPLACEMENT.) 6. Remove the CKP sensor. (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION.) 7.

How does a crank pulley work on a Mazda 3?

There is a flat metal plate hooked onto the crankshaft pulley that has teeth on it that spins through the crank position sensor to help the ECU in determaining fuel timing and what not. You can’t just remove one and put on the new one.

Is it safe to remove the crank bolt on a Mazda?

Since removing the crank bolt releases the crank gear, allowing it to rotate on the shaft, the only safe way is to install the locking tools. Like any other chain, there can be some teething problems, and Mazda had some when it went to chains.

Why is my timing belt not working on my Mazda?

Or, you may see P0011 or P0012 DTCs, indicating the cam timing is not as expected. This code could be as simple as the oil level being low, but it could also be the result of a worn chain or actuator. We’ll take a look at the nuts and bolts and some of the pitfalls you may encounter on belt replacement for an early 2000 Mazda.

How do you suspend a chain in a Mazda 6?

1. Using a thin screwdriver, hold the chain tensioner ratchet lock mechanism away from the ratchet stem. 2. Slowly compress the tensioner piston. 3. Hold the tensioner piston using a 1.5 mm {0.059 in} wire or paper clip. Suspend the engine using the SSTs .

Can a crank pulley be removed without a timing cover?

Unless the crank pulley is radically different then any other car I have seen you can remove the crank pulley without removing the timing chain, so you don’t have to lock the cams together. The design has a pulley outside of the timing cover and a cogged gear inside of the timing cover on the end of the crank shaft.

Do you need an owner’s manual to change a timing chain?

Locate your owner’s manual. You will most likely need it to disassemble and reassemble various parts. Also verify that your model is equipped with a timing chain and not a timing belt. These two parts perform the same task, but replacing them can be quite different. This procedure is only for replacing a timing chain.

What should I do to tighten my timing chain?

Tighten the chain according to your car manual’s specifications. Some chains are tensioned by adjusting either the crankshaft gear or the camshaft gear, while others have an automatic tensioner. This will vary by make and model of your car. The important thing is to make sure that your timing belt is as tight as it should be.

When to replace timing belt on Mazda 2000?

We’ll take a look at the nuts and bolts and some of the pitfalls you may encounter on belt replacement for an early 2000 Mazda. As always, review your service information before you dive in. It may just save you some valuable time and needless aggravation.

When to replace timing chain on Mazda Speed 3?

Timing chains don’t typically need replacement unless you achieve massively high mileage. Most will be good for the life of the engine. Timing belts are quieter, reduce friction, and don’t stretch like chains, but they need replaced at regular intervals, typically around 100k anymore.

How is the timing belt installed on a Mazda 6?

3) On the six, there’s a suggested procedure for belt installation with the goal being to end with some tension between the crank and cams, with the slack on the tensioner side. 4) With the belt in place, install the tensioner plunger, remove the pin and rotate the engine two revolutions.

Do you have to change timing chain in front wheel drive car?

No such luck if you have a modern front-wheel drive car with a transversely-mounted engine, as the space in the engine compartment could be very tight. To avoid timing chain problems you should maintain your engine properly and have the engine oil changed at recommended intervals. Using premium quality engine oils and oil filters will also help.

Can a timing chain be replaced on a pushrod car?

In old-style pushrod engines, replacing the timing chain is a fairly easy task. No such luck if you have a modern front-wheel drive car with a transversely-mounted engine, as the space in the engine compartment could be very tight.

How is the SST installed on a Mazda 6?

1. Install the SST to the camshaft as shown. 2. Install the M6 x 1.0 bolt in by hand. 3. Turn the crankshaft clockwise the crankshaft is in the No.1 cylinder TDC position. 4. Hold the crankshaft pully by using the SST .

What should I do if my engine timing is wrong?

If the engine runs rough after correcting cam timing, perform a compression test. If compression is low, perform a cylinder leakdown test and determine leakage. Replace the cylinder head if necessary. Follow specific procedures to time LF 2.0L and L3/L3T 2.3L engines.

How to timing a LF 2.0L engine?

Timing the LF / 2.0L engine, the L3 and L3T / 2.3L engines must be done following specific procedures. This Job Aid explains how to verify base engine timing (relation of intake camshaft, exhaust camshaft, crankshaft sprocket and crankshaft pulley) and how to correct timing if it is incorrect.
