How do I know if my 2000 Daihatsu 1.0 Sirion's timing is not right?
Answered by CarsGuide
17 Jan 2024Assuming you mean the Daihatsu's ignition timing, the on-board computer should control the timing. If this is out of whack, you'll find the car could be difficult to start, will idle poorly, use more fuel than it should, be down on power and may even overheat. Or all of those things. For reference, the correct timing for this engine is five degrees before top dead centre (+ or – two degrees) at idle. It can be checked by a workshop to verify whether it's correct or not.
If you're referring to the engine's valve timing, that's a different thing altogether. You need to reset the valve timing whenever you change the rubber toothed timing belt to avoid catastrophic damage to the engine. The valve timing of the car should not change between belt-change intervals, but if it has, then the damage has probably already been done. Again, for reference, the two camshafts need to be lined up with their respective timing marks, along with the crankshaft in its correct position before the new belt is fitted. This is not a simple job for a Saturday morning in the driveway.
