Do you have to be dead on with timing belt alignment?

Because modern vehicles use so many electronics to control the engine with things such as crank and camshaft timing sensors, technicians need to be, as we say in the industry, “dead-on” with the timing belt alignment. The cam gear cannot be off by even a tooth, or the engine will set a DTC.

How often do timing belts need to be replaced?

While timing belts have been steadily getting replaced by chains due to their longer service life, belt manufacturers have made strides to improve their belt life to more than 100,000 miles, in some cases. Even though belts will not last as long as a chain, they are quieter and often easier to line up correctly with the cam and crank locked down.

What can cause a tripped cam sensor code?

The most common cause of a tripped cam sensor code, according to a belt manufacturer, is the misalignment between the rear cam gear and timing belt. A DTC can be triggered with the cam gear being one tooth advanced or retarded.

Loosen the middle tensioner cog in the middle of the timing configuration; it’s smaller than the two cams and will have a bolt on it. As you’re loosening the bolt, push down on the spring and move it downwards. Then, tighten the bolt to lock it in place.

Why do you need to lock down the timing belt?

Even though belts will not last as long as a chain, they are quieter and often easier to line up correctly with the cam and crank locked down. Anytime the belt is removed, the cam and crank need to be aligned to TDC No.1, which is where the marks on the crankshaft pulley line up with the pointer on the front cover.

Do you have to torque the idler before replacing a timing belt?

Put a drop of red threadlocker on all the bolts for these parts. Torque the hydraulic tensioner bolts to 100 lbs and the roller tensioner to 35 ft lbs. You do not need to torque the idler until you put the new timing belt.

Can a crank bolt be removed from a Toyota V-8?

An impact gun can usually remove the crank bolt, but the pulley may still need to be held in place. Certain Toyotas and Lexus V-8 engines with overhead cams use a belt that winds all the way around both banks and an idler pulley, tensioner and crank gear, so proper alignment is critical, especially if it’s an interference engine.
