It's not about time. You should change the timing belt every 90k miles.
To set the timing on a 1990 Toyota Camry, first ensure the engine is off and cool. Locate the timing marks on the crankshaft pulley and the timing cover, then use a timing light to check the current timing. Adjust the timing by loosening the distributor clamp bolt and rotating the distributor until the timing mark aligns with the specified degree in the service manual, then retighten the bolt. Finally, recheck the timing to ensure it’s set correctly.
The Echo doesn't have a timing belt. It has a timing chain, and this chain will last a very long time. Toyota doesn't recommend replacing it (as a preventative or maintenance measure) unless or until you have problems.
The cam chain will last the life of the engine and need not be replaced until the engine is overhauled.
5x100 until 1992. 92 on is 5x114.3
R12. I don't think 134a can into use until around 1996.
You suppose to change it on 90000 miles. Now it's like the russion rulet you might get lucky or not.
you don't need to replace the timing chain until it becomes noisy
The Camry could have a vacuum leak. If there is a vacuum leak, then there can be a whistling sound until the vacuum system is full of air.
Drain it out until it is on the full mark of the dipstick
To replace the fuel filter on a 1997 Toyota Camry, first, relieve the fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls. Next, locate the fuel filter, which is typically found along the chassis under the vehicle. Disconnect the fuel lines from the filter using appropriate tools, and then remove the old filter. Install the new filter in the same orientation, reconnect the fuel lines, and replace the fuse before starting the engine to check for leaks.
It is very easy to disable a Toyota Camry's car alarm. There is a toggle switch underneath the dashboard, on the left side of the steering wheel. Flip the switch while starting the car until you hear a beep. This disables the car alarm.
The Toyota Camry was introduced in 1983 as a replacement for the Corona. The initial body style was replaced in 1987 and continued until 1992 , when a more rounded, and slightly larger vehicle was introduced. The next restyling was in 2002 and changed very little until the most recent generation which began with the 2007 model introduction.
