What happens when you change the timing belt?
He changed the timing belt, drive belts, water pump, pulleys, tensioner and a few hoses, and everything seemed to go off without a hitch. After picking up the car, though, we noticed that the idle seemed much rougher than it had in the past.
What should I do if my timing was not set correctly?
There is a code that should get set if the timing was not set correctly, and it is the type that really should have triggered an engine light within a few hundred miles (I would actually think pretty much immediately).
Can a timing belt go over two pulleys?
If the configuration of the t-belt is that it goes over two camshaft pulleys, well it is very easy to get that wrong. When it goes over only one cam shaft pulley it is smooth sailing, very difficult to get it wrong, but over two, many more ways to get it off a tooth or two. So that’s a possibility.
Can a balance shaft be off timing time?
If you have balance shafts, one of them could be off time. That would be more likely to me because if the cams were off timing, you should get a check engine light and notice a serious drop in power and fuel economy, enough so that you would not have forgotten to mention it in your post.

What happens when the timing belt is worn out?
A worn out timing belt might also impact the engine’s fire rate. The timing belt is attached to pulleys that drive the crank and camshaft as we’ve indicated above. However, sometimes the belt will slip on the camshaft drive and cause one cylinder to open or close earlier than it should.
What should be the distance between timing belt pulleys?
The straightedge should be long enough to span the distance between the two outside edges of the timing belt pulley faces. Lay the ruler across the face of the two timing belt pulleys, if the two timing belt pulley faces are not even with the straightedge than you have parallel misalignment.
What causes angular misalignment on timing belt pulleys?
Angular misalignment is where the driver and driven shafts are not parallel. Resulting in uneven loading of the timing belt tensile cords. The tensile cords on the high tension side are often overloaded which may cause edge cord failure which would be transmitted across the width of the timing belt.
What are the symptoms of a faulty timing belt?
Ticking noise coming from the engine. The timing belt is attached by way of a series of pulleys to the engine’s crank and cam shaft. The crankshaft powers the engine’s connecting rods which are attached to pistons inside the combustion chamber. The camshaft operates the cylinder head valves and rocker arm assembly, which…
What does the pulley on the timing belt do?
The snakelike timing belt on the side of the engine is essential for maintaining your car’s performance. It is controlled by a round pulley called a tensioner that keeps the line taught as it rotates. More often than not, the tensioner goes bad before the timing belt does.
Where to look for a timing belt tensioner?
You will see a smooth belt wrapped around several pulleys. The tensioner can be tricky to spot, so look for a helpful sticker placed in the engine bay. The tensioner positioning varies depending on the vehicle you have. If your car doesn’t have a sticker in the engine bay, look through the owner’s manual for a diagram.
What should I do if my car does not start after replacing the timing chain?
If your car does not start after timing chain or belt replacement, or the car does not start after engine rebuild this video will explain what to do and what to expect. When replacing timing belt or chain or cylinder head often the fuel injectors will need to be removed or the fuel line will need to be disconnected.
What are the symptoms of a bad timing chain?

The first is the two-gear method, which includes 2 2. Metal shavings found in the oil. 3 3. Engine won’t start or fails. 4 4. Check Engine Light is on. 5 5. Engine rattles while idling.
Can a fuel pump belt not be adjusted?
If not the car will probably not start or run roughly. The new timing belts are often shorter than the old one, and your pump mark will not be in the same place as before and your engine will probably not run well. In this case, you have to find a repair manual of how to adjust the fuel pump timing.
Can a leaking timing belt cause an engine to overheat?
Leaking oil from the timing belt cover commonly results in engine overheating as well and can prematurely wear the timing belt. Often, it’s difficult to discover a problem with the timing belt until it’s too late and has broken.

When to go to the Mechanic about a bad timing chain?
If the belt is jumping because it’s gotten loose, it can also flail around and damage other parts of the engine. If your engine won’t start or starts driving rough, indicating it may be on its way to failing, contact a certified mechanic for inspection and repairs. 4. Check Engine Light is on
Leaking oil from the timing belt cover commonly results in engine overheating as well and can prematurely wear the timing belt. Often, it’s difficult to discover a problem with the timing belt until it’s too late and has broken.
Secondly, the timing belt itself may slowly wear away, mainly on the ‘teeth’ of the belt that grip onto the camshaft and crankshaft pulleys. Over time, these points can wear away on the timing belt, leading to slight changes in the engine timing.
Why is the T Belt Light not switching off?
2 days ago the T Belt light came on. No biggie, I thought. Take off the rubber cover on the speedo and press with a thin screwdriver. Problem is it does seem to spring up and down. I checked on my other 80 and it definitely does not move even 1 mm. Any suggestions what I can do?
When did Honda Pilot timing belt come out?
Changed out Honda Pilot Timing Belt at 101000 miles. CEL, VSC, VTM lights all came on as I pulled out of garage. Did battery disconnect reset. Drove 60 miles, CEL and VSC came on. Reset again and drove a bit. Came on again. Then CEL started flashing and car shuddered.
Why did my water pump break while replacing the timing belt?
They admitted that while replacing the timing belt, one of the other belts also being replaced (with the water pump) had broken and damaged the sensor in some way (the mechanic admitted to this, but the front desk guy had led me to believe otherwise).
When to know if your timing belt needs to be replaced?
Between about 60,000 miles and 90,000 miles when your belt might still be good, and it might not still be good. If you notice any of these signs in your car, then you should probably get yourself to a mechanic so they can take a look and see if your belt needs to be replaced.
When to change timing belt on Honda Civic?
I had my timing belt changed for my 2001 Honda Civic on Friday at 110K miles. Before I took the car into the shop, there were no problems. Ten minutes after driving away, the check engine light came on, and the car had trouble running and starting later in the day.
How does the timing belt reset switch work?
The switch connects to a tiny black box (just right of the green wires in the first image) which appears to count revolutions of the 10,000 section of the odometer, via the very top shaft connected to the counters by a cog. The only mechanical part of the Timing Belt reset process appears to be the button.
Can a crank pulley be removed from a timing belt?
The crank pulley is the main pulley at the bottom of the engine. It needs to be removed in order to change the timing belt. However, it’s not easy if you only have hand tools, since the torque on this bolt is often pretty extreme.
What happens when your timing belt gives up the ghost?
Your engine’s timing belt is the most important maintenance item in your car. What happens when this component gives up the ghost, and how hard is it to fix by yourself? What Is A Timing Belt? A timing belt is the ribbed belt that is placed in a specific configuration along one side of your engine to keep the crank and camshafts timed properly.
Can a timing belt change cause rough idle?
Just throwing a possibility out there simply because it has been known to happen before.
When do you change the timing belt on a car?
Last week, we had the timing belt changed by a mechanic I’ve gone to for the past four years and trust a great deal. He changed the timing belt, drive belts, water pump, pulleys, tensioner and a few hoses, and everything seemed to go off without a hitch.
When to replace timing belt on Honda Accord?
Hondas can go as much as 105,000 miles before they need the timing belt replaced. However, some models have a shorter recommended interval. Some need to be replaced at 90,000 miles, so, again, check your owner’s or repair manual.
When to replace timing belt on Acura 3.2 liter?
Acuras have one of the longest intervals for timing belt replacement. Most models, like those with 3.2-liter engines, do not need their timing belt replaced until they hit 92,000 miles or after six years, whichever comes first.

What happens if the timing belt goes on a non interference engine?
Non-interference engines do not risk this contact if the timing belt goes. Nonetheless, a failed timing belt will leave you stranded with either type of engine, so it is important to know the replacement interval for your specific model and have your belt replaced accordingly.
Can a bad timing belt cause an engine to misfire?
Since a bad timing belt can put a damper on the firing rate of the engine, it will likely cause the engine to misfire. This will happen if a worn-out timing belt were to slip off its pulley and fall onto the camshaft drive. Then the timing of when the cylinder opens and closes would be thrown off, which would cause a misfire for sure.
Can a bad timing belt cause oil pressure to drop?
The only thing you can do at this point is to install a new timing belt before the engine gets seriously damaged (if that hasn’t already occurred). As a timing belt starts to get excessive wear, pieces of its teeth will come loose and break off into the oil pan of the vehicle. This will cause a significant drop in the oil pressure of the engine.

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.
