How to replace a timing belt on a Toyota Camry?
Therefore, you can use the instructions below to replace a broken timing belt on a non-VVTI engine. Positioning the camshaft sprockets and the crankshaft pulley alignment marks to Top Dead Center (TDC) is all you need to do before installing the new belt.
What should I do before replacing my timing belt?
Positioning the camshaft sprockets and the crankshaft pulley alignment marks to Top Dead Center (TDC) is all you need to do before installing the new belt. After installing the belt, you can do a compression leakage test to make sure the valves are still okay.
What does it mean to re-install timing chain?
Which means to align the crank timing marks and the cam timing marks to spec, then re-install the timing chain. Before moving the cam or crank, find a copy of the manufacturer’s procedure on how to do this without banging the valves into the piston or the valves into the valves. The method varies engine to engine.
Can you rotate the cam shaft on an OHC engine?
Rotating the camshaft on an OHC engine is easy to do when your pulling the head. And even just changing the chain. If the crankshaft is turned to put the timing mark 90* before top dead center, all 4 pistons will be half way down their bores and you can spin the camshaft with no chance of a piston/valve collision.
What should the cam timing be on a DOHC engine?
If the cam timing was set to this smaller/narrower 110.5 degree lobe separation angle, the engine would behave much differently than the 113.5 degree lobe separation angle.
Where to find the TDC on a DOHC engine?
Finding the REAL TDC is a must A piston stop can be used to find the actual TDC position for the piston in the cylinder when the head(s) are on the engine. Most engines will have timing marks on both cam sprockets. On the RB26DETT engine, the dot on the cam sprocket lines up to a dash mark on the back cover.
What happens if your camshaft timing is not correct?
If you answered “yes” to any of those questions, your camshaft timing may not be what the camshaft manufacturer specified. Improper cam timing can lead to reduced performance, increased fuel consumption and an increased likelihood of detonation.
Is it necessary to degree your DOHC engine?
While taking the time to degree the cam on a SOHC engine may be unnecessary if a chassis dyno will be used in the future for tuning the cam sprocket, taking the time to degree the camshafts on DOHC (double over- head camshaft) engines can avoid some serious potential headaches.
Therefore, you can use the instructions below to replace a broken timing belt on a non-VVTI engine. Positioning the camshaft sprockets and the crankshaft pulley alignment marks to Top Dead Center (TDC) is all you need to do before installing the new belt.
What kind of engine does a Toyota Camry have?
The Toyota MZFE engine is a transversely-mounted, timing-belt driven, 24-valve, dual overhead cam (DOHC) aluminum V6 design.

When to replace timing belt and related parts?
When to Replace the Timing Belt and Related Parts. Toyota recommends belt replacement after 90,000 miles. Other parts are often replaced at the same time. Some shops always replace the water pump with the belt, but in my experience the Aisin water pumps that come with the MZFE Camry are good for at least 200,000 miles.
What causes the timing belt to jump position?
After many tens of thousands of miles, the teeth can wear or break, or the belt can stretch, thus causing the belt to jump position on the crankshaft or camshaft gears. Should the belt jump, the engine will run poorly and perhaps not at all.
How to replace timing belt on Toyota Landcruiser 1HZ?

When to replace timing belt on Toyota 4Runner?
4Runner Owners of V6 4Runners from 1990 to 2002 will need to replace their timing belt every 60k, while owners of V8 engines from 2003 to 2009 need to think about a belt replacement every 90k miles.
