Is this the solution for a starter motor that whirs and does not engage?
Coincedentally the bottom water hose of the radiator leaks, so must have been running hot.

I don't believe it has a belt !!!!!!!!!!!!!!!!
The one I have 2003 Toyota Corolla has timing chain.
And I think all 2003 Toyota Corolla have timing chains.
So don't let them ( workshops) lie to you.

SOURCE: my corolla pings alot

Number of possibilities.
One rare situation is that accumulated carbon in the head can increase compression and require a switch to premium gas.
Another is that the compression is supposed to be high but that they count on the EGR to poison the mixture enough to prevent it. So a malfunctioning EGR can cause ping.
Another is that the in some cars, the centrifugal or vacuum advance can be weak and cause timing to be too advanced when reved up.
Most cars also have a knock sensor that is supposed to automatically prevent ignition timing advance if the fuel is not up to it, and it could be bad.

First thing I would try is a tank full of premium, or an octane additive. Then I would try backing off the ignition timing, regardless of what the spec says it is supposed to be. I would also check the timing with all hoses on, with a strobe light, and at high RPM, to check advance.

Husband car slowed down on highway. Wont let him go 60 he has to pull over and park car what's wrong with it? He just had timing belt changed and oil leak sealed.

The first thing I would have checked is the cylinder compression. When things just "happen" it is often related to the most recent maintenance performed. By doing a compression check, if the cylinder compression is low, that would indicate that the timing belt slipped or jumped time, indicating something was installed, adjusted, or tightened correctly. If the compression is good and even on all cylinders, then you need to look for other possible problems.

Speedometer jumping up and down and car will not pick up speed.

Based on your actions, it sounds like a wiring problem.
Could be a weak connection at the cluster, or the speed sensor.

Low compression in all cylinders on a 98 toyota corolla

all 4 cylinders are at 50 psi?did you remove all of the spark plugs to do a compression test?do you have a quality compression gauge ?do you have the right fitting installed in the spark plug hole, and is it tight?
if so. your next step is to preform a cylinder leak down test. you will need an air compressor to so of the best things about your toyota is that it is a non interference engine. which means if the timing belt jumped, you wont damage any valves. be sure to check you timing marks before you decide to just junk the could have some bad valves, or just need new rings!definetly keep searching before you junk the car!start by checking the timing, and then do the leak down test.

Changed serpentine belt still not running, checked timing belt, it looks fine. checked compression, read 20, 20, 40, 20psi, from left to right if looking from front of car.... help.

If the spark plugs were fuel fouled, you could have washed the oil off the cylinder walls causing the low compression.
Or the cam timing could be off because the timing belt jumped a few teeth, or the cam gear broke.
I would pull the fuel pump fuse or relay and try to dry out the cylinders first.
And re-check the timing belt. The serpentine belt would not have any connection to the car not starting.

Loud exhaust

Loud noise from Exhaust means your exhaust system is leaking.
this will make the performance poor on your vehicle.

Get that check and replaced.

Timing on 85 toyot corolla / et up

If you mean how to install timing belt, I'm not sure on your corrolla, but on my old tercel I turned the crank pulley so that cylinder 1 was at its top height (by feeling with a screwdriver in sparkplug hole) then turned valve pulley until first valve was open (with valve cover off) then aligned the timing belt that way. It didn't work. Then I realized that the cylinder has 2 top positions, one for "compress" stroke and one for "push out exhaust", so I turned crank again to bring cylinder one to top height, aligned belt, and it worked, car started.

Then I realized that crankshaft pulley had a ''timing mark'' (a kind of little notch) on it and that it aligned perfectly with a mark on engine, just to prove that I had done it right, "by hand".

Hope the info helps ya !

I have a 2003 Chevy cavalier that will not start or even try. It cranks fine, I have verified it has spark, I replaced the plugs and crank shaft position sensor, timing chain is intact, but I didn't...

you may need to check the compression. if the plugs have fuel on them and you know the spark is good then the only thing missing for the car to run is the compression. if all the cylinders have low compression then the car has jumped time most likely.

Timing settings

my jeep has jumped time and i need to know the exact degrees to set it at please and thank you.


The first thing you need to do is to find out why it jumped time. Jumping time is not normal and shouldn't happen.

Tell me the last repair that was done on the jeep.

When was the timing belt last changed?

Were OEM parts used?

Were tensioners and pulleys changed?

2005 Toyota Corolla with 36,000 miles Transmission now "jumps" into gears

when the check engine light comes on, your car goes into a mode where instead of everything being normal, things are forced, to try and compensate for something else being wrong. It most likely does need a new timing belt, and a complete tuneup INCLUDING plugs and wires. we have a 1984 toyota corolla and it purrs like ground rice, I suggest the tuneup to continue proper rice production.
