Daihatsu Sirion Q&As

Check out real-world situations relating to the Daihatsu Sirion here, particularly what our experts have to say about them.

• Where is the oil filter in the transmission of a 2004 Daihatsu Sirion?

  Unlike fuel and oil filters which are often located in easily accessible places and are able to be removed and replaced easily, most automatic transmission filters are located inside the actual transmission. Usually, this means removing the transmission's pan which is also usually the way to access the transmission's valve body and other parts that are part of a transmission service.

  The best way to access this area is to have the car on a hoist and work from underneath.

• How to check if my 2000 Daihatsu Sirion's timing is right

  Assuming 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.

• I have a Daihatsu Sirion GTvi with an ABS warning light that continually lights up.

  If the ABS and overall braking system is working properly, then the warning light you’re seeing is probably being caused by a sensor or part of the electrical circuit involved in controlling the ABS. An electronic scan of the car’s on-board computer should give you an insight into what’s wrong and you can work forward from there. Simply replacing bits and pieces in the hope that they fix the problem is often a very time and money consuming way to go about this. Most workshops will be able to scan the car and interpret the fault codes.

• What happened to temperature gauges?

  I think you can safely assume that it's cost cutting, but it's probably a reflection of today's drivers who rarely look at their gauges anyway and wouldn't know what a temperature is trying to tell them. I too prefer a gauge as you see what's happening before it gets to the point of serious damage to the engine, but the red light if observed and acted upon should provide sufficient warning of trouble. Like you I also believe a tachometer is a not needed in most cars.
