Is the timing belt on a Camry 3mzfe interchangeable?
Most engine components in the 1MZFE are interchangeable with the 3MZFE, including the timing belt, tensioner pulley, and guide pulley, although the 3MZFE has a different tensioner configuration. See my other article for replacement of a timing belt on the four-cylinder Camry (the 5SFE engine).
Where is the timing belt on a transverse 4 cylinder engine?
On most transverse four-cylinder engines, you’ll have to remove the passenger-side motor mount in order to gain access to the timing belt. This means the entire powertrain needs to be supported in that area while you’re working. And finally, getting to the lower portion of multipiece timing belt covers usually requires underbody access.
Where are the timing marks on a timing belt?
(2a) Find the timing marks on the flywheel and cam, and set them both to TDC. (2b) The flywheel pulley TDC mark is accessible through a hole in the bellhousing. (2c) The camshaft TDC is easy to find — especially if you add white paint as we did.
Why does my engine have low compression after a timing belt replacement?
If you know that you got low compression after a timing belt replacement, check the timing. Anyways, if you experience low compression on all cylinders, check the timing. These are found between the crankshaft and camshaft. Valves control the outflow of exhaust gases from the combustion chambers.
What happens if you have a broken cam belt?
Broken pistons and valves – a completely broken belt means that the camshaft and the crankshaft will become desynchronised, resulting in the pistons coming into contact with the valves as they open, damaging the valves and pistons. If you know the belt is gone – then this is a very good reason for turning off the engine immediately.
What happens if the timing belt breaks on a Toyota Camry?
In models before the 1999-2003 introduction of VVTI (Variable Valve Timing) technology, the engine’s valve train is “non-interference,” meaning that if the timing belt breaks while the vehicle is operating, it will not necessarily damage the valves or pistons.
Which is more important the camshaft or the timing belt?
Let’s state it plainly – nothing is more important than the timing belt. It drives the camshaft, which is what keeps the valves synchronized, and the crankshaft, which controls the pistons. Your timing belt tells the pistons when to rise and fall, and the valves when to open and close.
What happens if the timing belt snaps on an interference engine?
While it is possible that no damage could occur from a snapped belt on an interference engine, such a case is unlikely. In a non-interference engine, the pistons and valves don’t occupy the same space, so if the timing belt snaps, no valve or cylinder damage occurs.
