When does a timing belt go slack after installation?
All timing belts stretch, and most of that stretch occurs about 15 minutes after installation. A spring-loaded tensioner keeps the belt tight, but after a while the tensioner will run out of travel and the belt will go slack.
What are the symptoms of a timing belt jumped?
Lost 40% of power also sounds like your charging system has taken a dump. Not enough current heading to the coils to fire the plugs hot I’ve seen that as well Pull a plug and see if it’s all sooty or clean. If it’s sooty and all plugged with carbon, that plug is firing real weak.
What happens when your timing belt skips a tooth?
It should only take 6 turns or less to get everything to line up like it should. If your CPS (crank position sensor) was covered in oil you might be leaking oil from your OEM CAMSHAFT OIL SEAL : MITSUBISHI ECLIPSE 90-99. As an example, heres what mine looked like when I skipped (2) teeth a few years back…
What should I do if my engine jumped timing?
If you suspect that your engine has jumped timing, don’t just let it go and hope for the best. Once the engine jumps a single tooth, it’s only a matter of time before it does it again and leaves you stranded or worse. At the very least, you’ll want to do some research and find out if your engine is an “interference” design.
What happens when the timing belt breaks on a car?
The level of damage caused by a broken timing belt can depend on the type of engine you have in your car. A non-interference engine provides clearance between the valves and pistons, so if the timing belt breaks, you might end up with bent valves, and you might have to have your cylinder heads rebuilt, but the engine isn’t likely to be destroyed.
How often should a timing belt be replaced?
Manufacturers employ various schedules and measures for timing belt replacement, but the rule of thumb is 60,000 miles, or 5 years, whichever comes first. Is My Engine Safe If My Timing Belt Snaps?
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.
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 should I do if my timing belt jumped?
Just take two pictures, one of your cam gears and one of your crank pulley and where its line up to TDC. It should only take 6 turns or less to get everything to line up like it should. If your CPS (crank position sensor) was covered in oil you might be leaking oil from your OEM CAMSHAFT OIL SEAL : MITSUBISHI ECLIPSE 90-99.
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.
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.
Where is the arrow on the timing belt?
Typically, there is a notch or a raised arrow on the bearing cap so it can be easily confirmed by eye when the two marks line up or, in the case of a stretched belt, do not line up.
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.
